[0053] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0054] In the description of this application, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0055] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.

[0056] In clinical practice, in order to meet the needs of health examinations of patients, it is often necessary to collect ECG data, for example, to collect 12-lead ECG data. However, 12-lead ECG data can only cover the anterior and inferior myocardium, and cannot fully cover other parts of the heart.

[0057] In order to obtain more ECG data, multiple leads are added to the 12-lead ECG measurement to obtain 15-lead ECG data or 18-lead ECG data. For example, when posterior wall myocardial infarction is suspected, 3 additional posterior wall leads are required; when right ventricular disease is suspected, 3 additional right chest leads are required.

[0058] Since the commonly used ECG acquisition device on the market is a 12-lead ECG acquisition device, when it is necessary to acquire ECG data of more than 12 leads, it is necessary to reuse some of the lead electrodes in the 12 leads for additional ECG acquisition after completing the 12-lead ECG acquisition, thereby achieving 15-lead ECG data acquisition or 18-lead ECG data acquisition.

[0059] During the reuse of some lead electrodes, in order to accurately obtain the corresponding ECG data, it is necessary to accurately adjust the relative position of the lead electrodes of the predetermined ECG leads on the target object. In the related technology, the instructions for adding leads during the reuse of some lead electrodes are unclear, so that during the execution of the lead-adding operation, the accuracy of the lead-adding operation depends on users with high professional operating skills, which makes the product usage experience have certain defects and is not conducive to product promotion.

[0060] Based on this, the present application provides an ECG acquisition method and device, which aims to assist users to complete the lead addition operation more accurately and efficiently, thereby improving the product user experience of the ECG acquisition device, wherein the ECG acquisition method is applied to the ECG acquisition device.

[0061] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings. In the absence of conflict, the features in the following embodiments and implementation methods can be combined with each other.

I / O interfaces include, but are not limited to, serial interfaces such as USB, IEEE1394, or RS-232C, parallel interfaces such as SCSI, IDE, or IEEE1284, and analog signal interfaces composed of D / A converters and transducers. The I / O interface is connected to an input component, which a user can use to directly input data into controller 30. The input component includes, but is not limited to, a keyboard, a mouse, a touch screen, or control buttons. The display component can communicate with controller 30 via the I / O interface to display relevant information. The communication interface can be an interface using any currently known communication protocol. The communication interface communicates with the outside world via a network. Controller 30 can transmit data between any component connected to the network using a preset communication protocol via the communication interface.

The historical ECG data is the data collected by the lead electrodes of the plurality of ECG leads obtained by the ECG acquisition device in response to the first acquisition instruction; the position correspondence is used to guide the user to move the lead electrode of the predetermined ECG lead from the first position to the second position, and the position correspondence The device comprises at least a first graphic element, a first position icon corresponding to the first position, a second position icon corresponding to the second position, and movement guide information for indicating the movement of the lead electrode of the predetermined ECG lead between the first position and the second position; the first graphic element is used to simulate the target object and / or simulate the area on the target object connected to the lead electrodes of the multiple ECG leads, and the first position icon is located on the first graphic element to indicate the position where the lead electrode of the predetermined ECG lead is connected to the target object during the process of collecting the historical ECG data; the second position icon is located on the first graphic element to indicate the position where the lead electrode of the predetermined ECG lead is to be connected on the target object;

[0094] The second acquisition instruction is received, and in response to the second acquisition instruction, the ECG acquisition host 10 is controlled to acquire the second ECG data acquired by the lead electrodes of the plurality of ECG leads.

[0095] It can be understood that the historical ECG data is conventional ECG data collected historically, and the second ECG data is additional ECG data.

[0096] It can also be understood that, in the process of verifying the historical ECG data of the target subject, the controller 30 executes:

[0097] The device receives a data selection instruction generated by the electrocardiogram acquisition device triggered by a user, and determines the historical electrocardiogram data of the target object according to the data selection instruction.

[0098] It should be noted that technical personnel in the relevant field can clearly understand that for the convenience and conciseness of description, the specific working process of the ECG acquisition method steps implemented by the controller described above can refer to the corresponding working process of the ECG acquisition method, and will not be repeated here.

[0099] See also Figure 2 , Figure 2 This is a flowchart of the steps of an ECG acquisition method provided in the first embodiment of the present application.

[0100] The ECG acquisition method is applied to the aforementioned ECG acquisition device 100 , which includes but is not limited to an electrocardiograph. The ECG acquisition method provided in the embodiment of the present application will be described below in conjunction with the working principle of the ECG acquisition device 100 .

[0101] like Figure 2 As shown, the ECG acquisition method includes steps S101 to S103.

[0102] Step S101: receiving a first acquisition instruction, and acquiring first electrocardiogram data acquired by lead electrodes of a plurality of electrocardiogram leads connected to a target object in response to the first acquisition instruction.

[0103] Step S102: Receive a continued acquisition instruction, and in response to the continued acquisition instruction, display a positional correspondence between a first position and a second position of a predetermined ECG lead among the multiple ECG leads, or display an information entry for viewing the positional correspondence between the first position and the second position, wherein the first position is used to indicate a position where the lead electrode of the predetermined ECG lead is connected to the target object during the process of acquiring the first ECG data, and the second position is used to indicate a position where the lead electrode of the predetermined ECG lead is to be connected on the target object, and the positional correspondence is used to guide a user to move the lead electrode of the predetermined ECG lead from the first position to the second position.

[0104] Step S103: receiving a second acquisition instruction, and acquiring second ECG data acquired by the lead electrodes of the plurality of ECG leads in response to the second acquisition instruction.

[0105] For example, ECG leads include limb leads and chest leads, where limb leads include lead I, lead II, lead III, aVR, aVL, and aVF. Chest leads include the six anterior chest leads and the back leads, including leads V1-V6 on the anterior chest, leads V7, V8, and V9 on the left posterior chest wall, and leads V3R, V4R, and V5R on the right chest.

[0106] ECG data includes 12-lead, 15-lead, and 18-lead lead types. Typically, when performing an ECG test on a target subject (e.g., a patient), medical personnel can first obtain the target subject's 12-lead ECG data and make a preliminary diagnosis based on the 12-lead ECG data.

[0107] When there are suspected diseases in the left ventricle or posterior wall of the heart, such as left ventricular hypertrophy or posterior wall myocardial infarction, it is difficult to confirm the diagnosis through the obtained 12-lead ECG data. It is necessary to add multiple leads on the basis of 12-lead measurement to obtain 15-lead ECG data or 18-lead ECG data. For example, when posterior wall myocardial infarction is suspected, 3 additional posterior wall leads are required; when right ventricular disease is suspected, 3 additional right chest leads are required.

[0108] Among them, the conventional 12 leads include limb leads (lead I, lead II, lead III, aVR lead, aVL lead, aVF lead) and chest leads V1-V6.

[0109] The 15-lead system includes limb leads and V7, V8, and V9 of the left posterior chest wall, or the 15-lead system includes limb leads and V3R, V4R, and V5R of the right chest.

[0110] The 18 leads include limb leads, V7, V8, and V9 leads on the left posterior chest wall, and V3R, V4R, and V5R leads on the right chest.

[0111] The right chest leads V3R, V4R, and V5R are mainly placed symmetrically with the corresponding left chest leads. The left posterior chest wall leads V7, V8, and V9 are usually placed at the posterior axillary line of the fifth intercostal space on the left side of the sternum, as well as the inferior angle of the scapula and the paraspinal line.

[0112] Since most ECG data acquisition devices are not equipped with more lead electrodes than required for conventional lead examinations (such as 12 leads), if left posterior chest or right chest leads are required, the user needs to manually adjust the corresponding lead electrodes and reuse the electrodes corresponding to the conventional lead examination for additional examinations, thereby obtaining 15-lead ECG data or 18-lead ECG data.

[0113] In addition, the reuse of electrodes during the process of adding leads must meet the following requirements: the electrode corresponding to the V1 lead is reused as the electrode of the V3R lead, the electrode corresponding to the V2 lead is reused as the electrode of the V4R lead, the electrode corresponding to the V3 lead is reused as the electrode of the V5R lead, the electrode corresponding to the V4 lead is reused as the electrode of the V9 lead, the electrode corresponding to the V5 lead is reused as the electrode of the V8 lead, and the electrode corresponding to the V6 lead is reused as the electrode of the V7 lead.

[0114] If the multiplexing order corresponding to each lead is wrong, the ECG data obtained by each lead will be wrong, and ultimately the ECG report output based on the ECG data will be wrong. Therefore, the accuracy of the lead addition operation depends on users with high professional operating skills.

[0115] In the embodiment of the present application, the first acquisition instruction is a conventional acquisition instruction, and the first ECG data is conventional ECG data. That is, the conventional acquisition instruction is used to control the ECG acquisition device 100 to acquire conventional ECG data of the target object, such as 12-lead ECG data.

[0116] The second acquisition instruction is an additional acquisition instruction, and the second ECG data is additional ECG data. That is, the additional acquisition instruction is used to control the ECG acquisition device to acquire additional ECG data of the target subject, such as leads V7, V8, and V9 of the left posterior chest wall, and / or leads V3R, V4R, and V5R of the right chest. By acquiring the target conventional ECG data and the additional ECG data, 15-lead ECG data or 18-lead ECG data of the target subject is obtained.

[0117] During the 12-lead ECG data acquisition process, the user selects the 12-lead option to be acquired on the ECG acquisition device 20 and then connects a plurality of lead electrodes 20 to preset positions on the human body.

[0118] The 12 leads include limb leads and 6 chest leads. The limb leads include lead I, lead II, lead III, aVR lead, aVL lead, and aVF lead. The corresponding 4 lead electrodes 20 need to be connected to the preset positions of the limbs of the target object.

[0119] like Figure 3 As shown, the RA electrode among the multiple lead electrodes 20 is connected to the right upper limb of the target object, the LA electrode among the multiple lead electrodes 20 is connected to the left upper limb of the target object, the LL electrode among the multiple lead electrodes 20 is connected to the left lower limb of the target object, and the RL electrode among the multiple lead electrodes 20 is connected to the right lower limb of the target object, and the limb lead data of the target object is obtained through the four lead electrodes.

[0120] The 6 chest leads are V1-V6 leads, which require 6 lead electrodes 20 to be connected to the 6 corresponding preset positions on the chest of the target object. Figure 3 As shown, the electrode corresponding to the V1 lead in the multiple lead electrodes 20 is connected to the V1 position of the 4th intercostal space on the right edge of the human sternum, the electrode corresponding to the V2 lead is connected to the V2 position of the 4th intercostal space on the left side of the human sternum, the electrode corresponding to the V4 lead is connected to the V4 position of the 5th intercostal space on the left side of the human sternum and the clavicle midline, and the electrode corresponding to the V3 lead is set at the V3 position between the V2 and V4 leads, the electrode corresponding to the V5 lead is connected to the V5 position at the intersection of the 5th intercostal space of the human sternum and the anterior axillary line, and the electrode corresponding to the V6 lead is connected to the V6 position at the intersection of the 5th intercostal space of the human sternum and the mid-axillary line.

[0121] After connecting the lead electrodes 20 corresponding to the 12-lead ECG data to be acquired to the corresponding parts of the target subject, the user triggers the first ECG acquisition entry provided by the interaction unit 40 to send a first acquisition instruction to the ECG acquisition device 100, so that the ECG acquisition device 100 responds to the ECG acquisition instruction and acquires the first ECG data of the target subject, that is, acquires the 12-lead ECG data of the target subject, namely, acquires the ECG data corresponding to lead I, lead II, lead III, lead aVR, lead aVL, lead aVF, and leads V1-V6, also known as conventional ECG data or standard 12-lead data.

[0122] After completing the first ECG data acquisition, if it is necessary to further acquire additional lead data of the target subject, a corresponding continued acquisition instruction is sent to the ECG acquisition device 100 by triggering a second ECG acquisition portal provided by the interaction unit 40. In response to the continued acquisition instruction, the ECG acquisition device 100 displays an electrode position adjustment guide that matches the continued acquisition instruction on the display interface of the display unit 101 of the ECG acquisition device 100. The electrode position adjustment guide is a graphical electrode position adjustment guide that includes a positional correspondence between a first position and a second position of a predetermined ECG lead among a plurality of ECG leads, or alternatively, displays an information portal for viewing the positional correspondence between the first position and the second position. The predetermined ECG lead is a lead for which electrode position adjustment is required. The first position indicates a position at which a lead electrode of the predetermined ECG lead is connected to the target subject during the acquisition of the first ECG data, and the second position indicates a position on the target subject at which the lead electrode of the predetermined ECG lead is to be connected. The positional correspondence guide guides a user to move the lead electrode of the predetermined ECG lead from the first position to the second position.

[0123] In the embodiment of the present application, the continuous acquisition instruction is used to trigger the ECG acquisition device 20 to display a graphical electrode position adjustment guide, so that the user can perform the lead addition operation according to the electrode position adjustment guide. Therefore, the continuous acquisition instruction is also called the add instruction. For ease of understanding, the continuous acquisition instruction will be uniformly referred to as the add instruction below. Figure 4 Taking right chest lead addition as an example, if the user wants to perform right chest lead addition on the target subject, the user sends a corresponding first addition instruction (e.g., right chest lead addition instruction) to the ECG acquisition device 100 via the interaction unit 40. After receiving the first addition instruction, the ECG acquisition device 100 displays a first graphical electrode position adjustment guide. The first electrode position adjustment guide shows that the leads requiring electrode position adjustment for right chest lead addition include lead V1, lead V2, and lead V3. The leads requiring electrode position adjustment are referred to as predetermined ECG leads.

[0124] That is, the lead electrodes that need to be adjusted are those corresponding to lead V1, lead V2, and lead V3. Furthermore, the corresponding lead electrodes must be reused in the following manner: the electrode corresponding to lead V1 is reused as the electrode for lead V3R, the electrode corresponding to lead V2 is reused as the electrode for lead V4R, and the electrode corresponding to lead V3 is reused as the electrode for lead V5R.

[0125] Therefore, the ECG acquisition device 100 displays on the corresponding display interface the first positions of the predetermined ECG leads V1, V2, and V3 connected to the target object during routine ECG acquisition, and the second positions of the electrodes corresponding to the predetermined ECG leads connected to the human body when additional lead data needs to be acquired, such as the 3R position corresponding to the right chest lead V3R, the 4R position corresponding to the V4R lead, and the 5R position corresponding to the V5R lead.

[0126] At the same time, it is displayed that the electrode corresponding to the V1 lead needs to be moved to the 3R position corresponding to the V3R lead to be used as the electrode of the V3R lead, the electrode corresponding to the V2 lead needs to be moved to the 4R position corresponding to the V4R lead to be used as the electrode of the V4R lead, and the electrode corresponding to the V3 lead needs to be moved to the 5R position corresponding to the V5R lead to be used as the electrode of the V5R lead, thereby giving the user a clear and precise electrode position adjustment guide, so that the user can accurately and efficiently perform electrode position adjustment according to the displayed electrode position adjustment guide.

[0127] After the user completes the electrode adjustment according to the electrode position adjustment guide, additional ECG data collection can be performed. The user sends a corresponding second collection instruction to the ECG collection device 100 through the interactive unit 40. The second collection instruction can then control the lead electrodes of multiple ECG leads connected to the target object to collect the second ECG data of the target object. That is, in this case, the second ECG data is the 15-lead ECG data of the right chest.

[0128] See also Figure 5 Taking the left posterior chest wall lead addition as an example, if the user wants to perform the left posterior chest wall lead addition on the target subject, the user sends a corresponding second addition instruction (e.g., a right chest lead addition instruction) to the ECG acquisition device 100 through the interaction unit 40. The ECG acquisition device 100 displays a second electrode position adjustment guide based on the received second addition instruction. The second electrode position adjustment guide indicates that the predetermined ECG leads required for electrode position adjustment for the left posterior chest wall lead addition include lead V4, lead V5, and lead V6.

[0129] That is, the lead electrodes that need to be adjusted are: the lead electrodes corresponding to lead V4, lead electrodes corresponding to lead V5, and lead electrodes corresponding to lead V6. Furthermore, the corresponding lead electrodes must be reused in accordance with the following rules: the electrode corresponding to lead V4 is reused as the electrode for lead V9, the electrode corresponding to lead V5 is reused as the electrode for lead V8, and the electrode corresponding to lead V6 is reused as the electrode for lead V7.

[0130] Therefore, the ECG acquisition device 100 displays on the corresponding display interface the first positions of the predetermined ECG leads V4, V5, and V6 connected to the target object during routine ECG acquisition, and the second positions of the electrodes corresponding to the predetermined ECG leads connected to the human body when additional lead data needs to be acquired, such as the V7 position corresponding to the left posterior chest wall lead V7, the V8 position corresponding to the V8 lead, and the V9 position corresponding to the V9 lead.

[0131] At the same time, it is displayed that the electrode corresponding to the V4 lead needs to be moved to the V9 position corresponding to the V9 lead to be used as the electrode of the V9 lead, the electrode corresponding to the V5 lead needs to be moved to the V8 position corresponding to the V8 lead to be used as the electrode of the V8 lead, and the electrode corresponding to the V6 lead needs to be moved to the V7 position corresponding to the V7 lead to be used as the electrode of the V7 lead, thereby giving the user a clear and precise electrode position adjustment guide, so that the user can accurately and efficiently perform electrode position adjustment according to the displayed electrode position adjustment guide.

[0132] After the user completes the electrode adjustment according to the electrode position adjustment guide, additional ECG data collection can be performed. The user sends a corresponding second collection instruction to the ECG collection device 100 through the interactive unit 40. The second collection instruction can then control the lead electrodes of multiple ECG leads connected to the target object to collect the second ECG data of the target object. That is, in this case, the second ECG data is the 15-lead ECG data of the left posterior chest wall.

[0133] See also Figure 6 Similarly, taking the addition of right chest and left posterior chest wall leads as an example, if the user wants to add right chest and left posterior chest wall leads to the target object, the user sends a corresponding third addition instruction (e.g., right chest and left posterior chest wall lead addition instruction) to the ECG acquisition device 100 through the interaction unit 40. The ECG acquisition device 100 displays a third electrode position adjustment guide based on the received third addition instruction. The third electrode position adjustment guide shows that the leads that need to be adjusted for the addition of right chest and left posterior chest wall leads include lead V1, lead V2, lead V3, lead V4, lead V5, and lead V6. The leads that need to be adjusted are called predetermined ECG leads.

[0134] That is, the lead electrodes that need to be adjusted are the lead electrode corresponding to lead V1, the lead electrode corresponding to lead V2, the lead electrode corresponding to lead V3, the lead electrode corresponding to lead V4, the lead electrode corresponding to lead V5, and the lead electrode corresponding to lead V6.

[0135] In addition, the reuse of corresponding lead electrodes must follow the following rules: the electrode corresponding to the V1 lead is reused as the electrode of the V3R lead, the electrode corresponding to the V2 lead is reused as the electrode of the V4R lead, the electrode corresponding to the V3 lead is reused as the electrode of the V5R lead, the electrode corresponding to the V4 lead is reused as the electrode of the V9 lead, the electrode corresponding to the V5 lead is reused as the electrode of the V8 lead, and the electrode corresponding to the V6 lead is reused as the electrode of the V7 lead.

[0136] Therefore, the ECG acquisition device 100 displays on the corresponding display interface the first positions at which the predetermined ECG leads V1, V2, V3, V4, V5, and V6 are connected to the target object during routine ECG acquisition, and the second positions at which the electrodes corresponding to the predetermined ECG leads are connected to the human body when additional lead data needs to be acquired, for example, the 3R, 4R, and 5R positions corresponding to the right chest leads V3R, V4R, and V5R, respectively, and the V7, V8, and V9 positions corresponding to the left posterior chest wall leads V7, V8, and V9, respectively.

[0137] At the same time, it is displayed that the electrode corresponding to the V1 lead needs to be moved to the 3R position corresponding to the V3R lead to be used as the electrode of the V3R lead, the electrode corresponding to the V2 lead needs to be moved to the 4R position corresponding to the V4R lead to be used as the electrode of the V4R lead, the electrode corresponding to the V3 lead needs to be moved to the 5R position corresponding to the V5R lead to be used as the electrode of the V5R lead, the electrode corresponding to the V4 lead needs to be moved to the V9 position corresponding to the V9 lead to be used as the electrode of the V9 lead, the electrode corresponding to the V5 lead needs to be moved to the V8 position corresponding to the V8 lead to be used as the electrode of the V8 lead, and the electrode corresponding to the V6 lead needs to be moved to the V7 position corresponding to the V7 lead to be used as the electrode of the V7 lead, thereby giving the user a clear and precise guide for adjusting the electrode position, so that the user can accurately and efficiently perform the electrode position adjustment according to the displayed electrode position adjustment guide.

[0138] After the user completes the electrode adjustment according to the electrode position adjustment guide, additional ECG data collection can be performed. The user sends a corresponding second collection instruction to the ECG collection device 100 through the interactive unit 40. The second collection instruction can then control the lead electrodes of multiple ECG leads connected to the target object to collect the second ECG data of the target object. That is, the second ECG data at this time is 18-lead ECG data of the right chest and left posterior chest wall.

[0139] In some embodiments, the position correspondence of the predetermined ECG lead includes at least a first graphic element, a first position icon corresponding to the first position, a second position icon corresponding to the second position, and movement guide information for indicating the movement of the lead electrode of the predetermined ECG lead between the first position and the second position; wherein, the first graphic element is used to simulate the target object and / or simulate the area on the target object connected to the lead electrodes of multiple ECG leads, the first position icon is located on the first graphic element to indicate the position where the lead electrode of the predetermined ECG lead is connected to the target object during the process of collecting the first ECG data; the second position icon is located on the first graphic element to indicate the position to be connected of the lead electrode of the predetermined ECG lead on the target object during the process of collecting the second ECG data, wherein the first graphic element can be one or more, optionally, there are 2-3 first graphic elements, and each first graphic element indicates a different part of the target object, for example, one first graphic element indicates the limbs of the target object, one first graphic element indicates the back of the target object, and one first graphic element indicates the chest of the target object.

[0140] Based on the positional correspondence of the predetermined ECG leads, the positional relationship between the lead electrodes of the predetermined ECG leads is indicated by graphic elements. Therefore, the positional correspondence of the predetermined ECG leads is a graphical positional correspondence.

[0141] Optionally, after the user scans the information entry displayed by the ECG acquisition device 100 through an electronic device, a graphical position correspondence between the first position and the second position of the predetermined ECG lead can be displayed on the display interface of the electronic device, where the electronic device includes but is not limited to a smart phone, a tablet computer, and a smart wearable device.

[0142] It can be understood that the position correspondence of the predetermined ECG leads is a position correspondence displayed graphically, which makes it easier for users to more intuitively obtain the position where the lead electrode of the predetermined ECG lead is connected to the target object during the process of obtaining the first ECG data, and the position to be connected with the target object during the process of obtaining the second ECG data.

[0143] It can also be understood that the first position icon and the second position icon are both used to simulate the lead electrodes of predetermined ECG leads. Specifically, the first position icon is used to simulate the lead electrodes of predetermined ECG leads in the process of collecting first ECG data, and the second position icon is used to simulate the lead electrodes of predetermined ECG leads in the process of collecting second ECG data.

[0144] like Figure 4As shown, if it is determined that the predetermined ECG leads for which the electrode positions are to be adjusted include lead V1, lead V2, and lead V3, first position icons corresponding to the initial positions of the electrodes corresponding to lead V1, lead V2, and lead V3 on the target object are displayed on the first graphic element. For example, the first position icons include a V1 icon corresponding to lead V1, a V2 icon corresponding to lead V2, and a V3 icon corresponding to lead V3.

[0145] At the same time, the first graphical element displays second position icons corresponding to the second positions on the target object where the electrodes corresponding to leads V1, V2, and V3 are to be connected, along with connection instructions for moving between the first and second positions. The second position icons include a 3R icon for lead V3R, a 4R icon for lead V4R, and a 5R icon for lead V5R.

[0146] Specifically, the first graphic element includes a limb graphic element for indicating the limbs of the human body and a chest graphic element for indicating the chest of the human body, wherein the position icons of the electrodes corresponding to the limb leads are set on the limb graphic elements to indicate during the electrocardiogram data acquisition process that the Ra electrode corresponding to the limb lead is connected to the right upper limb of the target object, the LA electrode corresponding to the limb lead is connected to the left upper limb of the target object, the LL electrode corresponding to the limb lead is connected to the left lower limb of the target object, and the RL electrode corresponding to the limb lead is connected to the right lower limb of the target object.

[0147] The position icons of the electrodes corresponding to the V1 lead, V2 lead, and V3 lead are set on the chest graphic element to indicate that during the first ECG data acquisition process, the electrode corresponding to the V1 lead is connected to the V1 position of the target object, the electrode corresponding to the V2 lead is connected to the V2 position of the target object, and the electrode corresponding to the V3 lead is connected to the V3 position of the target object.

[0148] During the second ECG data collection process, the electrode corresponding to the V1 lead needs to be connected to the 3R position of the target object, the electrode corresponding to the V2 lead needs to be connected to the 4R position of the target object, and the electrode corresponding to the V3 lead needs to be connected to the 5R position of the target object.

[0149] At the same time, a migration arrow is set between the V1 position and the 3R position to guide the user to move the electrode corresponding to the V1 lead to the 3R position corresponding to the V3R lead, so as to be used as the electrode of the V3R lead.

[0150] A migration arrow is set between the V2 position and the 4R position to guide the user to move the electrode corresponding to the V2 lead to the 4R position corresponding to the V4R lead, so as to be used as the electrode of the V4R lead.

[0151] By setting a migration arrow between the V3 position and the 5R position, the electrode corresponding to the V3 lead is moved to the 5R position corresponding to the V5R lead to be used as the electrode of the V5R lead, thereby achieving precise position adjustment of the predetermined ECG lead.

[0152] like Figure 5 As shown, if it is determined that the predetermined ECG leads for which the electrode positions are to be adjusted include lead V4, lead V5, and lead V6, first position icons corresponding to the initial positions of the electrodes corresponding to lead V4, lead V5, and lead V6 on the target object are displayed on the first graphic element. For example, the first position icons include a V4 icon corresponding to lead V4, a V5 icon corresponding to lead V5, and a V6 icon corresponding to lead V6.

[0153] At the same time, the first graphic element displays second position icons corresponding to the second positions on the target object to which the electrodes corresponding to leads V4, V5, and V6 are to be connected, along with connection instructions for moving between the first and second positions. The second position icons include a V7 icon corresponding to lead V7, a V8 icon corresponding to lead V8, and a V9 icon corresponding to lead V9.

[0154] Specifically, the first graphic elements include a limb graphic element for indicating the limbs of a human body, a chest graphic element for indicating the chest of a human body, and a back graphic element for indicating the back of a human body.

[0155] Among them, the position icons of the electrodes corresponding to the limb leads are set on the limb graphic elements to indicate during the ECG data acquisition process that the Ra electrode corresponding to the limb lead is connected to the right upper limb of the target object, the LA electrode corresponding to the limb lead is connected to the left upper limb of the target object, the LL electrode corresponding to the limb lead is connected to the left lower limb of the target object, and the RL electrode corresponding to the limb lead is connected to the right lower limb of the target object.

[0156] The position icons of the electrodes corresponding to the V4 lead, V5 lead, and V6 lead are set on the chest graphic element to indicate that during the first ECG data acquisition process, the electrode corresponding to the V4 lead is connected to the V4 position of the target object, the electrode corresponding to the V5 lead is connected to the V5 position of the target object, and the electrode corresponding to the V6 lead is connected to the V6 position of the target object.

[0157] During the second ECG data collection process, the electrode corresponding to lead V4 needs to be connected to the V9 position of the target object, the electrode corresponding to lead V5 needs to be connected to the V8 position of the target object, and the electrode corresponding to lead V6 needs to be connected to the V7 position of the target object.

[0158] At the same time, a migration arrow is set between the V4 position and the V9 position to guide the user to move the electrode corresponding to the V4 lead to the V9 position corresponding to the V9 lead, so as to be used as the electrode of the V9 lead.

[0159] A migration arrow is set between the V5 position and the V8 position to guide the user to move the electrode corresponding to the V5 lead to the V8 position corresponding to the V8 lead, so as to be used as the electrode of the V8 lead.

[0160] By setting a migration arrow between the V6 position and the V7 position, the electrode corresponding to the V6 lead is moved to the V7 position corresponding to the V7 lead to be used as the electrode of the V7 lead, thereby achieving precise position adjustment of the predetermined ECG lead.

[0161] like Figure 6 As shown, similarly, if it is determined that the predetermined ECG leads for which the electrode positions are to be adjusted include leads V1 to V6, then first position icons corresponding to the initial positions of the electrodes corresponding to lead V1, lead V2, lead V3, lead V4, lead V5, and lead V6 on the target object are displayed on the first graphic element, such as the first position icons including the V1 icon corresponding to lead V1, the V2 icon corresponding to lead V2, the V3 icon corresponding to lead V3, the V4 icon corresponding to lead V4, the V5 icon corresponding to lead V5, and the V6 icon corresponding to lead V6.

[0162] At the same time, leads V1 to V6 are displayed on the first graphic element, and the second position icons corresponding to the second positions of the corresponding electrodes to be connected on the target object are displayed. For example, the second position icons include a 3R icon corresponding to lead V3R, a 4R icon corresponding to lead V4R, a 5R icon corresponding to lead V5R, a V7 icon corresponding to lead V7, a V8 icon corresponding to lead V8, and a V9 icon corresponding to lead V9.

[0163] Specifically, the first graphic elements include a limb graphic element for indicating the limbs of a human body, a chest graphic element for indicating the chest of a human body, and a back graphic element for indicating the back of a human body.

[0164] Among them, the position icons of the electrodes corresponding to the limb leads are set on the limb graphic elements to indicate during the ECG data acquisition process that the Ra electrode corresponding to the limb lead is connected to the right upper limb of the target object, the LA electrode corresponding to the limb lead is connected to the left upper limb of the target object, the LL electrode corresponding to the limb lead is connected to the left lower limb of the target object, and the RL electrode corresponding to the limb lead is connected to the right lower limb of the target object.

[0165] The position icons of the electrodes corresponding to leads V1 to V6 are set on the chest graphic element to indicate that during the first ECG data acquisition process, the electrode corresponding to lead V1 is connected to the V1 position of the target object, the electrode corresponding to lead V2 is connected to the V2 position of the target object, and the electrode corresponding to lead V3 is connected to the V3 position of the target object; the electrode corresponding to lead V4 is connected to the V4 position of the target object, the electrode corresponding to lead V5 is connected to the V5 position of the target object, and the electrode corresponding to lead V6 is connected to the V6 position of the target object.

[0166] During the second ECG data collection process, the electrode corresponding to the V1 lead needs to be connected to the 3R position of the target object, the electrode corresponding to the V2 lead needs to be connected to the 4R position of the target object, the electrode corresponding to the V3 lead needs to be connected to the 5R position of the target object, the electrode corresponding to the V4 lead needs to be connected to the V9 position of the target object, the electrode corresponding to the V5 lead needs to be connected to the V8 position of the target object, and the electrode corresponding to the V6 lead needs to be connected to the V7 position of the target object.

[0167] At the same time, a migration arrow is set between the V1 position and the 3R position to guide the user to move the electrode corresponding to the V1 lead to the 3R position corresponding to the V3R lead, so as to be used as the electrode of the V3R lead.

[0168] A migration arrow is set between the V2 position and the 4R position to guide the user to move the electrode corresponding to the V2 lead to the 4R position corresponding to the V4R lead, so as to be used as the electrode of the V4R lead.

[0169] By setting a migration arrow between the V3 position and the 5R position, the electrode corresponding to the V3 lead is moved to the 5R position corresponding to the V5R lead to be used as the electrode of the V5R lead, thereby achieving precise position adjustment of the predetermined ECG lead.

[0170] A migration arrow is set between the V4 position and the V9 position to guide the user to move the electrode corresponding to the V4 lead to the V9 position corresponding to the V9 lead, so as to be used as the electrode of the V9 lead.

[0171] A migration arrow is set between the V5 position and the V8 position to guide the user to move the electrode corresponding to the V5 lead to the V8 position corresponding to the V8 lead, so as to be used as the electrode of the V8 lead.

[0172] By setting a migration arrow between the V6 position and the V7 position, the electrode corresponding to the V6 lead is moved to the V7 position corresponding to the V7 lead to be used as the electrode of the V7 lead, thereby achieving precise position adjustment of the predetermined ECG lead.

[0173] Optionally, the movement guidance information includes at least one of a movement guidance text, a movement guidance path, and a movement guidance direction.

[0174] Optionally, at least some of the icons in the first location icon and the second location icon have different icon attributes, and the icon attributes include at least one of icon color, icon shape, and icon size.

[0175] For example, the icon attributes of at least some of the icons in the first location icon are different, or the icon attributes of at least some of the icons in the second location icon are different, or the icon attributes of the first location icon and the second location icon are different, and the icon attributes include at least one of the icon color, icon shape, and icon size. Each location icon is identified by different icon attributes, which is convenient for quickly distinguishing the location icons.

[0176] Optionally, the predetermined position correspondence of the electrocardiogram leads further includes a first position name corresponding to the first position and a second position name corresponding to the second position, and the first position name and the second position name are different.

[0177] For example, if it is necessary to add the right chest lead, that is, the predetermined ECG leads that need to be moved include V1 lead, V2 lead, and V3 lead, then the first position names can be V1 corresponding to V1 lead, V2 corresponding to V2 lead, and V3 corresponding to V3 lead, and the second position names can be 3R corresponding to V3R lead, 4R corresponding to V4R lead, and 5R corresponding to V5R lead.

[0178] Similarly, if it is necessary to perform an additional left posterior chest wall lead, that is, the predetermined ECG leads that need to be moved include V4, V5, and V6, then the first position names can be V4 corresponding to V4 lead, V5 corresponding to V5 lead, and V6 corresponding to V6 lead, and the second position names can be V9 corresponding to V9 lead, V8 corresponding to V8 lead, and V7 corresponding to V7 lead.

[0179] It is understandable that the naming of the position names can be adjusted as needed, as long as it is convenient for the user to know the name information of the electrodes of the predetermined ECG leads before and after the adjustment.

[0180] In some embodiments, the predetermined position correspondence relationship of the ECG leads is displayed in at least one of the following ways: at least through a static image display, at least through a dynamic image display, and at least through a video display.

[0181] Optionally, the method of displaying at least via a static image includes: displaying via a static image in combination with at least one of text and voice. For example, the first graphical element, the first location icon, the second location icon, and the movement guidance information may be displayed via a static image. Alternatively, the first graphical element, the first location icon, and the second location icon may be displayed via a static image, and the movement guidance information may be displayed via text. Alternatively, the first graphical element, the first location icon, and the second location icon may be displayed via a static image, and the movement guidance information may be output via voice announcement.

[0182] Optionally, the at least dynamic image display method includes: combining a dynamic image with at least one of text and voice. For example, the first graphical element, the first location icon, the second location icon, and the movement guidance information are displayed via a dynamic image. Alternatively, the first graphical element, the first location icon, and the second location icon are displayed via a dynamic image, and the movement guidance information is displayed via text. Alternatively, the first graphical element, the first location icon, and the second location icon are displayed via a dynamic image, and the movement guidance information is output via voice broadcast.

[0183] Optionally, at least the method of displaying through video includes: combining video with at least one of text and voice.

[0184] In some embodiments, the information entry includes at least a QR code, and the QR code is configured to display a position correspondence between the first position and the second position on a display interface of the electronic device after being scanned by the electronic device.

[0185] It can be understood that the information entry can also be other forms of coding. After the user scans the information entry through an electronic device, the graphical position correspondence between the first position and the second position can be displayed on the display interface displayed on the display screen of the electronic device. The electronic device includes but is not limited to smart phones, tablet computers, and smart wearable devices.

[0186] In some embodiments, after step S103, the method further includes: outputting a conventional electrocardiogram based on the first electrocardiogram data or the historical electrocardiogram data, and / or outputting an additive electrocardiogram based on the second electrocardiogram data.

[0187] See also Figure 7 and Figure 8 , exemplarily, after acquiring the first electrocardiogram data or the historical electrocardiogram data, a conventional electrocardiogram is output according to the first electrocardiogram data or the historical electrocardiogram data, such as Figure 7 As shown, a conventional electrocardiogram (also called a conventional electrocardiogram report) includes electrocardiogram data (such as electrocardiogram waveforms) corresponding to lead I, lead II, lead III, aVR lead, aVL lead, aVF lead, and leads V1-V6.

[0188] After obtaining the second ECG data, an ECG is generated based on the second ECG data output, such as Figure 8 As shown, the additional electrocardiogram (also called additional electrocardiogram report) is performed by adding the right anterior chest and left posterior chest wall leads, and the electrocardiogram data (such as electrocardiogram waveform) corresponding to lead I, lead II, lead III, aVR lead, aVL lead, aVF lead, V3R lead, V4R lead, V5R lead, V7 lead, V8 lead, and V9 lead are displayed.

[0189] In some embodiments, the conventional electrocardiogram includes a first name corresponding to a predetermined electrocardiogram lead, and the additional electrocardiogram includes a second name corresponding to the predetermined electrocardiogram lead, and the first name and the second name are different.

[0190] Exemplarily, data from the supplementary electrocardiogram is acquired by reusing lead electrodes corresponding to predetermined electrocardiogram leads. In a conventional electrocardiogram, the name of the predetermined electrocardiogram lead is a first name. In the supplementary electrocardiogram, the electrocardiogram acquisition device can determine a second name for the predetermined electrocardiogram lead in the supplementary electrocardiogram based on a received supplementary instruction, and modify the first name of the predetermined electrocardiogram lead to the second name when generating the supplementary electrocardiogram.

[0191] For example, in the case of right chest lead addition, the predefined ECG leads that need to be reused are V1, V2, and V3, and the predefined ECG leads in a conventional ECG are named V1, V2, and V3. In the added ECG, the electrode corresponding to lead V1 is reused as the electrode of lead V3R, the electrode corresponding to lead V2 is reused as the electrode of lead V4R, and the electrode corresponding to lead V3 is reused as the electrode of lead V5R. Therefore, when generating the added ECG, lead V1 is modified to lead V3R, lead V2 is modified to lead V4R, and lead V3 is modified to lead V5R, so that medical staff can easily know that the ECG data obtained by the current added ECG is the ECG data corresponding to the right chest lead addition.

[0192] In some embodiments, after outputting a conventional electrocardiogram based on the first electrocardiogram data or the historical electrocardiogram data and outputting an additive electrocardiogram based on the second electrocardiogram data, the method further includes:

[0193] Display a conventional electrocardiogram, and when a first display switching instruction is received, switch the conventional electrocardiogram to an additional electrocardiogram; or display an additional electrocardiogram, and when a second display switching instruction is received, switch the additional electrocardiogram to a conventional electrocardiogram.

[0194] Exemplarily, the first display switching instruction and the second display switching instruction are instructions generated by the user triggering the interaction unit 40. The interaction unit 40 can be a physical button provided on the ECG acquisition host 10, or a remote control communicatively connected to the ECG acquisition host 10, or a predetermined area on the display unit 101, or a virtual button provided on a display interface corresponding to the display unit 101.

[0195] For example, a virtual button is set on the ECG report preview interface for switching the display of conventional ECG and additional ECG. The user triggers the virtual button by clicking, double-clicking, pressing for a preset time, sliding, etc., thereby switching the display between conventional ECG and additional ECG.

[0196] like Figure 7 As shown, triggering the "General" virtual button under the "View Report" option on the ECG report preview interface will display the target subject's general ECG report on the interface.

[0197] like Figure 8 As shown, triggering the "Add" virtual button under the "View Report" option on the ECG report preview interface will display the target subject's additional ECG report on the interface.

[0198] In some embodiments, the first acquisition instruction is generated by an external object (e.g., a user) triggering a first ECG acquisition portal of the interaction unit 40, and the second acquisition instruction is generated by an external object (e.g., a user) triggering a second ECG acquisition portal of the interaction unit 40; wherein the first ECG acquisition portal includes at least one of a button provided on the ECG acquisition device 100, a touch component provided on the ECG acquisition device 100, and a virtual icon displayed on a display interface of the ECG acquisition device 100, and / or the second ECG acquisition portal includes at least one of a button provided on the ECG acquisition device 100, a touch component provided on the ECG acquisition device 100, and a virtual icon displayed on a display interface of the ECG acquisition device 100.

[0199] In some embodiments, the first ECG acquisition entrance is a first virtual icon displayed on the display interface of the ECG acquisition device 100, and the second ECG acquisition entrance is a second virtual icon displayed on the display interface of the ECG acquisition device 100, wherein the first virtual icon and the second virtual icon can be displayed simultaneously on the same display interface of the ECG acquisition device 100.

[0200] In some embodiments, the display interface of the ECG acquisition device 100 includes a real-time ECG interface for displaying real-time ECG data of the target object, a report preview interface for previewing an ECG report generated based on the real-time ECG data, and a historical ECG interface for displaying historical ECG data; wherein the first virtual icon and the second virtual icon are simultaneously displayed on at least one of the real-time ECG interface, the report preview interface, and the historical ECG interface.

[0201] In some embodiments, the display interface of the ECG acquisition device includes a real-time ECG interface for displaying real-time ECG data acquired by lead electrodes of multiple ECG leads, a report preview interface for previewing an ECG report generated based on the real-time ECG data, and a historical ECG interface for displaying historical ECG data;

[0202] The addition instruction is generated by triggering an addition entry by an external object (e.g., a user), and the addition entry includes at least one of a button provided on the ECG acquisition device 100, a touch component provided on the ECG acquisition device 100, and a virtual icon displayed on a display interface of the ECG acquisition device 100; wherein the addition entry is provided on at least one of a real-time ECG interface, a report preview interface, and a historical ECG interface;

[0203] When the add entry on the report preview interface or the historical ECG interface is triggered, the second ECG data is associated with the first ECG data, so that the ECG corresponding to the first ECG data and the ECG corresponding to the second ECG data are displayed in the same ECG report;

[0204] When the addition entry on the real-time ECG interface is triggered, the ECG corresponding to the first ECG data and the ECG corresponding to the second ECG data are respectively displayed in different ECG reports during the ECG report output process.

[0205] See also Figure 9 For example, during a regular ECG report preview on the report preview interface of the ECG acquisition device 100, if additional ECG data needs to be collected, the additional ECG data to be collected can be selected by triggering an additional entry (such as a "Add" virtual button) set on the report preview interface, thereby generating a corresponding additional instruction, so that the ECG acquisition device 100 responds to the additional instruction and displays an electrode position adjustment guide adapted to the additional instruction.

[0206] The electrode position adjustment guide is used to display the position correspondence between the first position and the second position of a predetermined ECG lead among multiple ECG leads, so that the user can adjust the position of each lead electrode connected to the target object according to the electrode position adjustment guide.

[0207] After the user completes the adjustment of each lead electrode according to the electrode position adjustment guide, a second acquisition instruction can be generated by triggering the second ECG acquisition entrance on the display interface (such as the "Start Acquisition" virtual button) to perform a second ECG data acquisition, that is, additional ECG acquisition.

[0208] At this time, the second ECG data of the target object collected by the ECG acquisition device 100 establishes a data association with the first ECG data that has been collected. After the second ECG data is data associated with the first ECG data, during the ECG report output process, the ECG corresponding to the first ECG data and the ECG corresponding to the second ECG data are displayed in the same ECG report, so that medical staff can obtain more complete ECG data of the target object in the same report.

[0209] See also Figure 10 When an addition entry on the real-time ECG interface (such as the V3R, V4R, V5R, V7, V8, and V9 options under the "12-lead" button, or the V3R, V4R, and V5R options under the "12-lead" button, or the V7, V8, and V9 options under the "12-lead" button) is triggered, a corresponding addition instruction is generated, so that the ECG acquisition device 100 responds to the addition instruction and displays an electrode position adjustment guide adapted to the addition instruction.

[0210] The electrode position adjustment guide is used to display the position correspondence between the first position and the second position of a predetermined ECG lead among multiple ECG leads, so that the user can adjust the position of each lead electrode connected to the target object according to the electrode position adjustment guide.

[0211] After the user completes the adjustment of each lead electrode according to the electrode position adjustment guide, a second acquisition instruction can be generated by triggering the second ECG acquisition entrance on the display interface (such as the "Start Acquisition" virtual button) to perform a second ECG data acquisition.

[0212] After the second ECG data collection is completed, the ECG corresponding to the first ECG data and the ECG corresponding to the second ECG data are respectively displayed in different ECG reports of the target object during the ECG report output process.

[0213] Please refer to Figure 10 When the addition entry on the real-time ECG interface (such as the 12-lead option under the "12-lead" button) is triggered, conventional electrode position guidance corresponding to conventional leads (12 leads) is displayed on the ECG acquisition device 100. The conventional electrode position guidance includes the connection position of the lead electrodes corresponding to the conventional 12 leads and the target object.

[0214] like Figure 3As shown, the conventional electrode position guide displays the connection positions of the four electrodes corresponding to the limb leads on the corresponding display interface, such as connecting the RA electrode of the non-scheduled ECG lead to the right upper limb of the target object, connecting the LA electrode in the non-scheduled ECG lead to the left upper limb of the target object, connecting the LL electrode in the non-scheduled ECG lead to the left lower limb of the target object, and connecting the RL electrode in the multiple lead electrodes 20 in the non-scheduled ECG lead to the right lower limb of the target object, and obtaining the limb lead data of the target object through the four lead electrodes.

[0215] At the same time, leads V1-V6 are displayed and connected to the corresponding 6 preset positions on the chest of the target object. The electrode corresponding to lead V1 in the multiple lead electrodes 20 is connected to the V1 position of the 4th intercostal space on the right edge of the human sternum, the electrode corresponding to lead V2 is connected to the V2 position of the 4th intercostal space on the left side of the human sternum, the electrode corresponding to lead V4 is connected to the V4 position of the 5th intercostal space on the left side of the human sternum and the clavicle midline, and the electrode corresponding to lead V3 is set at the V3 position between leads V2 and V4, the electrode corresponding to lead V5 is connected to the V5 position at the intersection of the 5th intercostal space of the human sternum and the anterior axillary line, and the electrode corresponding to lead V6 is connected to the V6 position at the intersection of the 5th intercostal space of the human sternum and the mid-axillary line.

[0216] After the lead electrodes are connected, the user can trigger the interaction unit 40 or the first ECG acquisition entry to send a first acquisition instruction to the ECG acquisition device 100, so that the ECG acquisition device 100 responds to the ECG acquisition instruction and acquires the first ECG data of the target object.

[0217] Please refer to Figure 10 When the addition entry on the real-time ECG interface (such as the 12-lead + V3R, V4R, V5R, V7, V8, and V9 options under the "12-lead" button) is triggered, the ECG acquisition device 100 determines that the user needs to acquire 18-lead ECG data of the target object by default, and then guides the user to the conventional electrode positions corresponding to the conventional leads (12 leads) on the display interface, so that the user can complete the acquisition of the target object's conventional ECG data (also called the first ECG data).

[0218] After the first ECG data collection is completed, an addition entry is displayed on the corresponding display interface, for example, a virtual icon of "Next" or "Add" is displayed on the corresponding display interface. When the user triggers the addition entry, the ECG acquisition device 100 receives a third addition instruction (for example, an instruction to add right chest and left posterior chest wall leads). The ECG acquisition device 100 displays a third electrode position adjustment guide based on the received third addition instruction. The third electrode position adjustment guide shows that the leads required for electrode position adjustment for adding right chest and left posterior chest wall leads include lead V1, lead V2, lead V3, lead V4, lead V5, and lead V6.

[0219] This helps the user to efficiently and accurately complete the connection between the lead electrodes and the target object, so that the user can efficiently obtain the second ECG data of the target object. Based on the first and second ECG data of the target object, that is, the 18-lead ECG data of the target object is obtained.

[0220] In some embodiments, the method further includes: the ECG acquisition device further displaying, in response to the instruction, a third position icon corresponding to a third position where a non-predetermined ECG lead (also known as a limb lead) among the plurality of ECG leads is connected to the target object, the third position icon being used to indicate a reference connection position between the lead electrode of the non-predetermined ECG lead and the target object;

[0221] When the lead electrode of the predetermined ECG lead is connected to the position indicated by the first position on the target object, and the lead electrode of the non-predetermined ECG lead is connected to the reference connection position of the target object, the ECG acquisition device can acquire the first ECG data of the target object through the lead electrodes of multiple ECG leads.

[0222] Among them, the non-predetermined ECG lead is a lead among the multiple ECG leads connected to the target object, and the electrode position does not need to be adjusted. Therefore, the non-predetermined ECG lead is a fixed ECG lead connected to a fixed position on the target object's body, that is, the non-predetermined ECG lead is a limb lead.

[0223] Exemplarily, after receiving the addition instruction, the ECG acquisition device 100 displays at least one of a position correspondence relationship between a first position and a second position of a predetermined ECG lead among a plurality of ECG leads and an information entry for viewing the position correspondence relationship between the first position and the second position, and a third position of a non-predetermined ECG lead among the plurality of ECG leads in response to the addition instruction; wherein the first position is used to indicate an initial connection position of a lead electrode of a predetermined ECG lead of the ECG acquisition device and a target object, the second position is used to indicate a position of the lead electrode of the predetermined ECG lead on the target object to be connected, and the position correspondence relationship is used to indicate an initial connection position of the lead electrode of the predetermined ECG lead of the ECG acquisition device and a target object, and the second position is used to indicate a position of the lead electrode of the predetermined ECG lead on the target object to be connected, and the position correspondence relationship is used to indicate an initial connection position of the lead electrode of the predetermined ECG lead of the ECG acquisition device and a target object to be connected, and the position correspondence relationship is used to indicate an initial connection ... The user is guided to move the lead electrode of the predetermined ECG lead from the first position to the second position; the third position is used to indicate the reference connection position of the lead electrode of the non-predetermined ECG lead and the target object. When the lead electrode of the predetermined ECG lead is connected to the initial connection position of the target object, and the lead electrode of the non-predetermined ECG lead is connected to the reference connection position of the target object, the ECG acquisition device can acquire the first ECG data of the target object through the lead electrodes of multiple ECG leads, wherein the initial connection position is the position where the lead electrode of the predetermined ECG lead needs to be connected to the target object during routine ECG acquisition.

[0224] like Figures 4 to 6As shown, after receiving the adjustment instruction, the ECG acquisition device 100 displays not only the positional correspondence between the first and second positions of the predetermined ECG lead to be adjusted, but also the third positional relationship of the non-predetermined ECG lead that does not require adjustment. Specifically, the corresponding display interface displays the connection positions of the four electrodes corresponding to the limb leads. For example, the RA electrode of the non-predetermined ECG lead is connected to the right upper limb of the target subject, the LA electrode of the non-predetermined ECG lead is connected to the left upper limb of the target subject, the LL electrode of the non-predetermined ECG lead is connected to the left lower limb of the target subject, and the RL electrode of the multiple lead electrodes 20 of the non-predetermined ECG lead is connected to the right lower limb of the target subject. Limb lead data of the target subject is acquired via these four lead electrodes.

[0225] See also Figure 11 , Figure 11 This is a flowchart of the steps of an ECG acquisition method provided in the second embodiment of the present application.

[0226] like Figure 11 As shown, the ECG acquisition method includes steps S201 to S203.

[0227] Step S201: Verify the historical ECG data of the target subject.

[0228] Step S202: Receive an addition instruction, and in response to the addition instruction, display a position correspondence between a first position and a second position of a predetermined ECG lead among a plurality of ECG leads, or display an information entry for viewing the position correspondence between the first position and the second position, wherein the historical ECG data is data collected by the lead electrodes of the plurality of ECG leads acquired by the ECG acquisition device in response to the first acquisition instruction; the first position is used to indicate a position at which the lead electrode of the predetermined ECG lead is connected to the target object during the process of collecting the historical ECG data, and the second position is used to indicate a position at which the lead electrode of the predetermined ECG lead is to be connected on the target object, and the position correspondence is used to guide a user to move the lead electrode of the predetermined ECG lead from the first position to the second position.

[0229] Step S203: Receive a second acquisition instruction, and in response to the second acquisition instruction, acquire second ECG data acquired by the lead electrodes of the plurality of ECG leads. Exemplarily, unlike the first embodiment, this embodiment determines the target object for additional ECG data acquisition based on historical ECG data.

[0230] The historical data of the target object includes at least identity information and historical ECG data, wherein the historical ECG data includes at least conventional ECG data of the target object collected historically, also referred to as first ECG data of the target object.

[0231] When historical data of the target object is already stored in a database (e.g., an ECG database), if more ECG data of the target object needs to be obtained, the historical data of the target object can be determined from the database to obtain the identity information of the target object. In this way, the user does not need to enter the identity information of the target object again during the additional ECG data collection process.

[0232] After determining the target subject for additional ECG data collection, the user triggers an additional entry (such as a virtual "Add" button) provided on the corresponding display interface of the ECG acquisition device 100 and selects the additional ECG data to be collected, thereby generating a corresponding additional instruction. The ECG acquisition device 100 responds to the additional instruction and displays an electrode position adjustment guide adapted to the additional instruction.

[0233] The electrode position adjustment guide is used to display the position correspondence between the first position and the second position of a predetermined ECG lead among multiple ECG leads, so that the user can adjust the position of each lead electrode connected to the target object according to the electrode position adjustment guide.

[0234] After the user completes the adjustment of each lead electrode according to the electrode position adjustment guide, a second acquisition instruction can be generated by triggering the second ECG acquisition entrance on the display interface (such as the "Start Acquisition" virtual button) to perform a second ECG data acquisition, that is, additional ECG acquisition.

[0235] See also Figure 12 , Figure 12 This is a flowchart of the steps of an ECG acquisition method provided in the third embodiment of the present application.

[0236] like Figure 12 As shown, the ECG acquisition method includes steps S301 to S303.

[0237] Step S301: Acquire the identity information of the target subject to be tested by electrocardiogram.

[0238] Step S302: Receive an add instruction, and in response to the add instruction, display a position correspondence between a first position and a second position of a predetermined ECG lead among a plurality of ECG leads, or display an information entry for viewing the position correspondence between the first position and the second position, wherein the first position is used to indicate an initial connection position of a lead electrode of a predetermined ECG lead of the ECG acquisition device and a target object, and the second position is used to indicate a position on the target object where the lead electrode of the predetermined ECG lead is to be connected, and the position correspondence is used to guide a user to move the lead electrode of the predetermined ECG lead from the first position to the second position, wherein the initial connection position is a position where the lead electrode of the predetermined ECG lead needs to be connected to the target object during a routine ECG acquisition process.

[0239] Step S303: receiving a second acquisition instruction, and acquiring second ECG data acquired by the lead electrodes of the plurality of ECG leads in response to the second acquisition instruction.

[0240] For example, the target subject's identity information can be obtained by a user inputting information into the ECG acquisition device via an input device, including but not limited to at least one of a keyboard, a mouse, a touch panel, and buttons. Alternatively, the user can manipulate the ECG acquisition device to obtain the information from a corresponding database, such as an ECG database, which can be a cloud database or a local database, without limitation.

[0241] What is different from the first embodiment is that in this embodiment, the additional ECG data of the target object is directly collected by obtaining the identity information of the target object without first obtaining the conventional ECG data of the target object.

[0242] The additional ECG data includes lead data such as V3R lead, V4R lead, V5R lead, or lead data such as V7 lead, V8 lead, V9 lead, or at least one of lead data such as V3R lead, V4R lead, V5R lead, V7 lead, V8 lead, V9 lead, etc.

[0243] See also Figure 10 When an addition entry on the real-time ECG interface (such as the V3R, V4R, V5R, V7, V8, and V9 options under the "12-lead" button, or the V3R, V4R, and V5R options under the "12-lead" button, or the V7, V8, and V9 options under the "12-lead" button) is triggered, a corresponding addition instruction is generated, so that the ECG acquisition device 100 responds to the addition instruction and displays an electrode position adjustment guide adapted to the addition instruction.

[0244] The electrode position adjustment guide is used to display the position correspondence between the first position and the second position of a predetermined ECG lead among multiple ECG leads, so that the user can adjust the position of each lead electrode connected to the target object according to the electrode position adjustment guide.

[0245] For example, if the V3R, V4R, and V5R options under the "12 Leads" button are triggered, an additional instruction for collecting lead data such as V3R, V4R, and V5R will be generated, and the following Figure 4 The electrode position adjustment guide is shown to guide the user to adjust each lead electrode.

[0246] Or, if the V7, V8, V9 options under the "12 Leads" button are triggered, then instructions for collecting lead data such as V7, V8, and V9 will be generated, and the following Figure 5 The electrode position adjustment guide is shown to guide the user to adjust each lead electrode.

[0247] Alternatively, if the V3R, V4R, V5R, V7, V8, and V9 options under the "12 Leads" button are triggered, an additional instruction for collecting lead data such as V3R, V4R, V5R, V7, V8, and V9 will be generated, and the following will be generated: Figure 6 The electrode position adjustment guide is shown to guide the user to adjust each lead electrode.

[0248] After the user completes the adjustment of each lead electrode according to the electrode position adjustment guide, a second acquisition instruction can be generated by triggering the second ECG acquisition entrance on the display interface (such as the "Start Acquisition" virtual button) to perform a second ECG data acquisition.

[0249] After the second ECG data collection is completed, the ECG corresponding to the first ECG data and the ECG corresponding to the second ECG data are respectively displayed in different ECG reports of the target object during the ECG report output process.

[0250] See also Figure 13 , Figure 13 This is a flowchart of the steps of an ECG acquisition method provided in the fourth embodiment of the present application.

[0251] like Figure 13 As shown, the ECG acquisition method includes steps S401 to S403.

[0252] Step S401: Acquire the identity information of the target subject to be tested by electrocardiogram;

[0253] Step S402: receiving an addition instruction, and in response to the addition instruction, displaying at least one of a position correspondence relationship between a first position and a second position of a predetermined ECG lead among a plurality of ECG leads and an information entry for viewing the position correspondence relationship between the first position and the second position, and a third position of a non-predetermined ECG lead among the plurality of ECG leads; wherein the first position is used to indicate an initial connection position of a lead electrode of a predetermined ECG lead of the ECG acquisition device and a target object, the second position is used to indicate a position of the lead electrode of the predetermined ECG lead on the target object to be connected, and the position correspondence relationship is used to guide the user to connect the predetermined ECG lead to the target object. The lead electrode of the predetermined ECG lead moves from the first position to the second position; the third position is used to indicate the reference connection position of the lead electrode of the non-predetermined ECG lead and the target object. When the lead electrode of the predetermined ECG lead is connected to the initial connection position of the target object and the lead electrode of the non-predetermined ECG lead is connected to the reference connection position of the target object, the ECG acquisition device can acquire the first ECG data of the target object through the lead electrodes of the multiple ECG leads, wherein the initial connection position is the position where the lead electrode of the predetermined ECG lead needs to be connected to the target object during conventional ECG acquisition.

[0254] Step S403: receiving a second acquisition instruction, and acquiring second ECG data acquired by lead electrodes of a plurality of ECG leads in response to the second acquisition instruction.

[0255] Illustratively, unlike the third embodiment, the data displayed by the ECG acquisition device 100 in response to the addition instruction in this embodiment also includes a third position of a non-predetermined ECG lead among the multiple ECG leads. The non-predetermined ECG lead is a limb lead, i.e., lead I, lead II, lead III, aVR lead, aVL lead, and aVF lead. The limb leads require the corresponding four lead electrodes 20 to be connected to preset positions on the limbs of the target subject.

[0256] like Figure 4 As shown, the Ra electrode among the multiple lead electrodes 20 is connected to the right upper limb of the target object, the La electrode among the multiple lead electrodes 20 is connected to the left upper limb of the target object, the LL electrode among the multiple lead electrodes 20 is connected to the left lower limb of the target object, and the LA electrode among the multiple lead electrodes 20 is connected to the left upper limb of the target object, and the limb lead data of the target object is obtained through these four lead electrodes.

[0257] In the process of directly acquiring additional ECG data of the target object, the specific connection position of each lead and the target object is displayed, so that the user can efficiently and accurately connect the lead electrodes corresponding to each lead to the target object, thereby efficiently and accurately acquiring additional ECG data of the target object.
