[0002] Electrocardiography (ECG) has been increasingly widely used in clinical practice, serving as an important clinical basis for diagnosing and differentiating arrhythmias, and also possessing significant clinical value in diagnosing acute myocardial ischemia / infarction. Currently, the Wilson lead system (and additional leads), Frank lead system, and the modified Mason-Likar lead system are commonly used for acquiring surface ECGs. The Wilson lead system provides a standard 12-lead (and additional leads) routine ECG; the Frank lead system provides orthogonal X / Y / Z lead ECGs, facilitating the observation of cardiac vectors; and the Mason-Likar lead system is primarily used for Holter monitoring, cardiac monitoring, and exercise stress testing. While ECGs acquired using these different lead systems and examination modes can all be used for the assessment and auxiliary diagnosis of myocardial ischemia or myocardial infarction, their sensitivity and specificity vary and all require further improvement.

[0011] The process includes evaluating the voltages of the first and second sets of leads to obtain the first ECG detection result, and then displaying the first ECG detection result and the ECG signal on the display interface.

[0012] Wherein, the voltage at the first central terminal is Vo = (VR + VL + VF) / 3; the voltage at the second central terminal is Vo_new = VR; where VR represents the voltage in the electrocardiogram signal corresponding to the right upper limb, VL represents the voltage in the electrocardiogram signal corresponding to the left upper limb, and VF represents the voltage in the electrocardiogram signal corresponding to the left lower limb.

[0013] To address the aforementioned issues, another technical solution adopted in this application is to provide an electrocardiogram (ECG) detection device, which includes a processor and a memory connected to the processor; wherein the memory is used to store program data, and the processor is used to execute the program data to implement the method provided by the above technical solution.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] See Figure 1 , Figure 1 This is a schematic flowchart of the first embodiment of the electrocardiogram (ECG) detection method provided in this application. The method includes:

[0031] Step 11: Obtain the electrocardiogram signal.

[0032] In some embodiments, the electrocardiogram (ECG) signal can be acquired by using an electrocardiograph (ECG) to collect ECG data from the subject. For example, the ECG may be an ECG using any of the Wilson lead system, the Frank lead system, or the modified Mason-Likar lead system.

[0033] In some embodiments, the ECG signal in step 11 can be acquired in real time or it can be historical data. For example, after each ECG signal acquisition of the user to be tested, the acquired ECG signal is stored so that subsequent ECG signal detection and traceability can be performed based on this ECG signal.

[0034] In one application scenario, ECG signal detection is centralized, meaning the detection and acquisition ends are not integrated. The acquisition end collects ECG signals from the user being tested, and then transmits the collected signals to the detection end for processing. This method allows for centralized ECG signal detection and centralized collection of abnormal results, improving the efficiency of handling these anomalies.

[0035] Step 12: Determine the first central terminal voltage using the electrocardiogram (ECG) signal, and determine the first set of lead voltages using the ECG signal and the first central terminal voltage; and determine the second central terminal voltage using the ECG signal, and determine the second set of lead voltages using the ECG signal and the second central terminal voltage; wherein the first central terminal voltage and the second central terminal voltage are different.

[0036] The first central terminal voltage can be any central terminal voltage corresponding to the Wilson lead system, Frank lead system, or the modified Mason-Likar lead system used by the electrocardiograph.

[0037] For example, an electrocardiograph (ECG) using the Wilson lead system can select a standard 12-lead, 15-lead, or 18-lead mode depending on the actual needs. After selecting the corresponding lead mode, electrode pads are placed on the corresponding sites of the user to collect ECG signals. After acquiring the ECG signals, the first central terminal voltage is determined using the ECG signals. The first central terminal voltage can be expressed as Vo = (VR + VL + VF) / 3, where VR represents the voltage corresponding to the right upper limb, VL represents the voltage corresponding to the left upper limb, and VF represents the voltage corresponding to the left lower limb. After obtaining the first central terminal voltage, the corresponding first set of lead voltages can be obtained based on the selected lead mode and the ECG signal. Taking a 12-lead system as an example, the first set of lead voltages includes: standard lead voltages (I, II, III), voltages of the compressed limb leads (aVR, aVL, aVF), and precordial lead voltages (V1-V6).

[0038] The second central terminal voltage can be expressed as Vo_new = VR; the corresponding second set of lead voltages can be obtained using the second central terminal voltage and the electrocardiogram signal. Taking twelve leads as an example, the second set of lead voltages can be obtained including: standard lead voltages (I′, II′, III′), pressure limb lead voltages (aV′R, aV′L, aV′F), and precordial lead voltages (V′1-V′6).

[0039] It can be understood that the second center terminal voltage can also be expressed as Vo_new = VL or Vo_new = VF. The corresponding second set of lead voltages can be calculated based on different second center terminal voltages.

[0040] Step 13: Evaluate the voltage of the first set of leads and the voltage of the second set of leads to obtain the first ECG test result.

[0041] In one application scenario, if an abnormality is found in the voltage of the first set of leads, the ECG signal corresponding to the voltage of the second set of leads can be detected to further confirm the abnormality and obtain the first ECG detection result.

[0042] In another application scenario, if no abnormality is found in the first set of lead voltages, the ECG signal corresponding to the second set of lead voltages can be detected to further determine if there is any abnormality, thus obtaining the first ECG detection result.

[0043] In another application scenario, the voltages of the first set of leads and the voltages of the second set of leads can be evaluated simultaneously to obtain the first ECG detection result.

[0044] In this embodiment, an electrocardiogram (ECG) signal is acquired; a first central terminal voltage is determined using the ECG signal; and a first set of lead voltages is determined using the ECG signal and the first central terminal voltage; a second central terminal voltage is determined using the ECG signal; and a second set of lead voltages is determined using the ECG signal and the second central terminal voltage; wherein the first central terminal voltage and the second central terminal voltage are different; the first set of lead voltages and the second set of lead voltages are evaluated to obtain a first ECG detection result. By providing two sets of lead voltages with different central terminal voltages, more useful ECG signals can be evaluated, improving the sensitivity and specificity of ECG signal diagnosis, and thus improving the accuracy of ECG detection.

[0045] See Figure 2 , Figure 2 This is a schematic flowchart of the second embodiment of the electrocardiogram (ECG) detection method provided in this application. The method includes:

[0046] Step 21: Obtain electrocardiogram (ECG) signal.

[0047] Step 22: Determine the first central terminal voltage using the electrocardiogram (ECG) signal, and determine the first set of lead voltages using the ECG signal and the first central terminal voltage.

[0048] Step 23: Evaluate the voltage of the first set of leads to obtain the second ECG test results.

[0049] In some embodiments, the second electrocardiogram (ECG) test results may include sinus rhythm, junctional rhythm, atrial premature contractions, ventricular premature contractions, sinus tachycardia, sinus bradycardia, atrial fibrillation, right atrial hypertrophy, left ventricular hypertrophy, myocardial ischemia, and acute phase of myocardial infarction.

[0050] Step 24: When the second ECG test result is abnormal, determine the second central terminal voltage using the ECG signal, and determine the second set of lead voltages using the ECG signal and the second central terminal voltage.

[0051] It is understandable that when the second ECG test result is abnormal, the voltage of the second set of leads can be determined based on the second terminal voltage to further confirm the abnormality and improve the accuracy of the test results.

[0052] Abnormal results include at least one of inferior wall and / or right ventricular ischemia / myocardial infarction, and ST-T changes in corresponding or adjacent leads.

[0053] See Figure 3 Step 24 can be specifically described as follows:

[0054] Step 241: Provide a display interface.

[0055] This display interface is understood to be a human-computer interaction interface, where users can make settings. For example, when setting the lead mode, users can select the standard 12-lead mode, the standard 15-lead mode, or the standard 18-lead mode. Users can also set the specific lead voltage in the second set of lead voltages.

[0056] Step 242: When the second ECG test result is abnormal, display the second central terminal voltage and the second set of lead voltages associated with the abnormal result on the display interface, and display a function button.

[0057] See Figure 4 When the second ECG test result is abnormal, the second central terminal voltage and the second set of lead voltages associated with the abnormal result will be displayed on the screen, along with a function button. The user can click this function button to proceed to step 243.

[0058] In other embodiments, the function button can be either a confirmation button or a cancel button. When the user clicks the confirmation button, step 243 is executed; when the user clicks the cancel button, the remaining steps are not executed, and an error result is directly output on the display interface.

[0059] In other embodiments, the user can also set the second central terminal voltage and the second set of lead voltages, and then click the function button. In response to the setting of the second central terminal voltage and / or the second set of lead voltages, and the clicking of the function button, the second central terminal voltage is determined using the ECG signal, and the second set of lead voltages are determined using the ECG signal and the second central terminal voltage. In this way, the second central terminal voltage and the second set of lead voltages are more correlated with abnormal results, and the detected ECG results are more accurate.

[0060] Step 243: In response to the function button being clicked, determine the second central terminal voltage using the ECG signal, and determine the second set of lead voltages using the ECG signal and the second central terminal voltage.

[0061] Step 25: Evaluate the voltage of the first set of leads and the voltage of the second set of leads to obtain the first ECG test result.

[0062] In this embodiment, by providing two sets of lead voltages with different central terminal voltages, more useful ECG signals can be evaluated, improving the sensitivity and specificity of ECG signal diagnosis, and thus enhancing the accuracy of ECG detection. Specifically, it can improve the sensitivity and specificity of ECG-based diagnosis of acute myocardial ischemia / myocardial infarction, especially by better utilizing ST segment changes as a diagnostic criterion for right ventricular ischemia / infarction, thereby improving its diagnostic sensitivity and accuracy. Furthermore, the interactive display interface enhances practical work efficiency, providing fast and efficient support for clinical diagnosis and treatment activities.

[0063] See Figure 5 , Figure 5 This is a schematic flowchart of the third embodiment of the electrocardiogram (ECG) detection method provided in this application. The method includes:

[0064] Step 51: Provide a display interface on which the second center terminal voltage and the second set of lead voltages can be set.

[0065] In other embodiments, the display interface can also set the lead mode corresponding to the first center terminal voltage.

[0066] Step 52: Obtain the electrocardiogram signal.

[0067] After setting the lead mode, the user places electrode pads on the body parts of the user to be tested in accordance with the method corresponding to the lead mode to obtain electrocardiogram signals.

[0068] Step 53: Determine the first central terminal voltage using the electrocardiogram (ECG) signal, and determine the first set of lead voltages using the ECG signal and the first central terminal voltage; obtain the setting parameters for the second central terminal voltage and at least one target lead voltage in the set second set of lead voltages; determine the second central terminal voltage using the setting parameters and the ECG signal, and determine at least one target lead voltage using the ECG signal and the second central terminal voltage.

[0069] In some embodiments, the second center terminal voltage can be expressed as Vo_new = VL or Vo_new = VF, or the second center terminal voltage can be expressed as Vo_new = VR. Corresponding options can then be set in the display interface, such as... Figure 6 As shown, the second center terminal voltage Vo_new = VL is displayed as second center terminal voltage A on the display interface, the second center terminal voltage Vo_new = VF is displayed as second center terminal voltage B, and the second center terminal voltage Vo_new = VR is displayed as second center terminal voltage C. The user can select from second center terminal voltages A, B, and C. After selection, another selection interface pops up, displaying the specific lead voltage in the second group of lead voltages. This allows for the selection of a target lead voltage. Figure 6 If the second center terminal voltage A is selected, a selection interface for the corresponding second center terminal voltage A will pop up. This selection interface displays the specific lead voltage in the second group of lead voltages associated with the second center terminal voltage A.

[0070] When determining the second center terminal voltage and the second set of lead voltages, the settings on the display interface are used as previously configured.

[0071] Step 54: Evaluate the voltage of the first set of leads and the voltage of the second set of leads to obtain the first ECG test result.

[0072] Step 55: Display the first ECG test result and ECG signal on the display interface.

[0073] In this embodiment, by providing two sets of lead voltages with different central terminal voltages, more useful ECG signals can be evaluated, improving the sensitivity and specificity of ECG signal diagnosis, and thus enhancing the accuracy of ECG detection. Specifically, it can improve the sensitivity and specificity of ECG-based diagnosis of acute myocardial ischemia / myocardial infarction, especially by better utilizing ST segment changes as a diagnostic criterion for right ventricular ischemia / infarction, thereby improving its diagnostic sensitivity and accuracy. Furthermore, the interactive display interface enhances practical work efficiency, providing fast and efficient support for clinical diagnosis and treatment activities.

[0074] See Figure 7 , Figure 7This is a schematic diagram of an embodiment of the electrocardiogram (ECG) detection device provided in this application. The ECG detection device 70 includes a sampling unit 71, a first lead processing unit 72, a second lead processing unit 73, and an analysis unit 74.

[0075] The sampling unit 71 is connected to the first lead processing unit 72 and the second lead processing unit 73 to acquire electrocardiogram signals.

[0076] The first lead processing unit 72 is used to determine the first central terminal voltage using the electrocardiogram signal, and to determine the first set of lead voltages using the electrocardiogram signal and the first central terminal voltage.

[0077] The second lead processing unit 73 is used to determine the second central terminal voltage using the electrocardiogram signal, and to determine the second set of lead voltages using the electrocardiogram signal and the second central terminal voltage.

[0078] The analysis unit 74 is connected to the first lead processing unit 72 and the second lead processing unit 73, and is used to evaluate the voltage of the first group of leads and the voltage of the second group of leads to obtain the first electrocardiogram detection result.

[0079] Among them, sampling unit 71 is for A / D sampling.

[0080] In one application scenario, the ECG electrodes are connected according to a commonly used clinical Wilson lead system, with one end connected to the human body and the other end connected to the sampling unit 71. The sampling unit 71 has a total of N input terminals, of which the limb leads are R for the right upper limb, L for the left upper limb, N for the right lower limb, and F for the left lower limb, with corresponding electrode recording voltages VR, VL, VN, and VF; the chest leads are Ci, and if there is an additional right chest lead, it is recorded as CiR, with corresponding electrode recording voltages V′i and V′iR.

[0081] The first lead processing unit 72 obtains the first central terminal voltage based on the electrocardiogram signal as Vo = (VR + VL + VF) / 3. The voltage of the first set of leads can be determined according to the corresponding electrocardiogram signal and the first central terminal voltage.

[0082] The second lead processing unit 73 obtains the second central terminal voltage, Vo_new = VR, based on the electrocardiogram signal. The voltages of the second set of leads can be determined according to the corresponding electrocardiogram signal and the second central terminal voltage.

[0083] In this embodiment, by providing two sets of lead voltages with different center terminal voltages, more useful ECG signals can be evaluated, which can improve the sensitivity and specificity of ECG signal diagnosis, thereby improving the accuracy of ECG detection.

[0084] In other embodiments, the first lead processing unit 72 is further configured to evaluate the voltage of the first group of leads to obtain the second ECG detection result; the second lead processing unit 73 is further configured to determine the second central terminal voltage using the ECG signal when the second ECG detection result is an abnormal result, and to determine the second group of lead voltages using the ECG signal and the second central terminal voltage.

[0085] In other embodiments, see Figure 8 The electrocardiogram (ECG) detection device 70 includes a sampling unit 71, a first lead processing unit 72, a second lead processing unit 73, an analysis unit 74, and a display screen 75.

[0086] The display screen 75 is used to display the second central terminal voltage and the second set of lead voltages associated with the abnormal result on the display interface when the second ECG test result is abnormal, and also displays a function button.

[0087] The second lead processing unit 73 is also used to determine the second central terminal voltage using the electrocardiogram signal in response to the function button being clicked, and to determine the second set of lead voltages using the electrocardiogram signal and the second central terminal voltage.

[0088] The second lead processing unit 73 is also configured to, in response to the setting of the second central terminal voltage and / or the second set of lead voltages and the clicking of the function button, determine the second central terminal voltage using the electrocardiogram signal, and determine the second set of lead voltages using the electrocardiogram signal and the second central terminal voltage.

[0089] The display screen 75 is also used to provide settings for the second center terminal voltage and the second set of lead voltages.

[0090] In one application scenario, the display screen provides a human-computer interaction interface for users to configure sampling settings, such as the examination type (resting ECG, monitoring ECG, etc.), lead mode (standard 12-lead, 15-lead, 18-lead, etc.), and whether to simultaneously output modified chest leads. After the settings are completed, the sampling unit 71 is used to acquire the human ECG signal.

[0091] The second lead processing unit 73 can be configured via a human-computer interface according to different lead modes and clinical needs, such as all chest leads, or some chest leads (e.g., additional right chest leads, V1-V3 leads), or turned off. It can also be set to default settings via software, such as all chest leads. If turned off, the second lead processing unit 73 will not be used in subsequent work.

[0092] The first lead processing unit 72 outputs the first set of lead voltages to the analysis unit 74. The analysis unit 74 uses a preset analysis algorithm to analyze the first set of lead voltages. If an abnormality is detected based on the analysis results of the first set of lead voltages, including characteristic abnormalities such as inferior wall and / or right ventricular (suspected) ischemia / myocardial infarction, and ST-T changes in the corresponding or adjacent leads, an abnormality prompt is displayed on the display screen 75; otherwise, the analysis results are output directly.

[0093] The analysis unit provides a recommended second central terminal voltage and second set of lead voltages based on the analysis results, and displays the new values ​​on the display screen 75. The user can modify, edit, or close the display screen via its human-computer interface. If closed, the analysis results are output directly; otherwise, the second lead processing unit 73 determines the second central terminal voltage using the ECG signal, and then determines the second set of lead voltages using both the ECG signal and the second central terminal voltage, outputting the second set of lead voltages to the analysis unit 74. The analysis unit 74 combines the first set of lead voltages and the second set of lead voltages for evaluation, obtaining the first ECG detection result.

[0094] The display screen 75 displays and stores the first ECG detection result and ECG signal, and provides a printing function.
