Description

[Technical Field]

[0001] The present invention relates to an electrocardiogram analyzer and a control method thereof. [Background technology]

[0002] Long-term electrocardiogram measurements using a Holter monitor are performed to detect symptoms such as arrhythmias that are difficult to detect with short-term measurements such as resting electrocardiograms taken during general routine health checkups. The quality of long-term electrocardiograms measured with a Holter monitor is not consistent and includes waveforms from tens of thousands of beats. For this reason, it is common for technicians and doctors to perform various analyses based on the results of automatic analysis by an electrocardiogram analyzer (Patent Documents 1 and 2).

[0003] Before measuring a long-term electrocardiogram, a medical technician uses an electrocardiogram analyzer to perform preparatory work such as recording information about the subject on a recording medium (for example, a memory card) used by a Holter electrocardiograph for electrocardiogram measurement.

[0004] When measuring a long-term electrocardiogram of a subject, it is common for a resting electrocardiogram to be measured before the long-term electrocardiogram. The resting electrocardiogram of the subject is a standard 12-lead electrocardiogram with high resolution, and is therefore thought to be useful, for example, in determining which leads to measure in preparation for the long-term electrocardiogram.

[0011] The present invention will be described in detail below based on exemplary embodiments with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the claimed invention. Furthermore, although multiple features are described in the embodiments, not all of them are necessarily essential to the invention, and multiple features may be combined arbitrarily. Furthermore, in the accompanying drawings, the same reference numerals are used to designate the same or similar components, and redundant explanations will be omitted.

[0012] In the following embodiments, the present invention will be described with reference to a general-purpose computer such as a personal computer or a tablet terminal, but the present invention can also be implemented in any electronic device, such as a media player, a smartphone, or a game console.

[0013] 1 is a block diagram showing an example of the functional configuration of a general-purpose computer 100 capable of functioning as an electrocardiogram analysis device according to this embodiment. A CPU 1 functioning as a control unit implements functions according to the program by, for example, reading a program stored in a storage device 10 into a RAM 3 and executing the program. For example, by executing a specific application program (electrocardiogram analysis application) while the operating system (OS) is running on the general-purpose computer 100, the general-purpose computer 100 functions as the electrocardiogram analysis device according to this embodiment.

[0014] The storage device 10 is, for example, a hard disk drive (HDD) or a solid state drive (SSD), and stores operating system (OS), device drivers, applications, user data, etc. The storage device 10 also stores GUI (Graphical User Interface) data for displaying menu screens, user setting data, initial setting data for applications, etc.

[0015] ROM2 stores programs, firmware, and various setting information required for starting up the computer, such as a bootstrap loader. At least a portion of ROM2 may be rewritable.

[0016] The RAM 3 is used as an area for expanding the programs executed by the CPU 1 and as a temporary storage area for variables, data, etc. Furthermore, part of the RAM 3 may be used as a video memory.

[0017] The memory card 4 is a recording medium that can be inserted into the card slot 5 and removed from the card slot 5. The general-purpose computer 100 can read data from the memory card 4 inserted into the card slot 5 and write data to the memory card 4. In this embodiment, the general-purpose computer 100 acquires data such as a long-term electrocardiogram recorded by a Holter electrocardiograph through the memory card 4. Note that the general-purpose computer 100 may acquire the electrocardiogram data to be automatically analyzed by other methods. For example, the electrocardiogram data to be automatically analyzed may be acquired from the Holter electrocardiograph that performed the measurement or from another external device 200 that stores the measured electrocardiogram data, by communication via a communication interface 20 (described later).

[0018] The display unit 6 includes a display device such as a liquid crystal display (LCD) or an organic EL display, a display control circuit, etc. Although Fig. 1 shows a configuration in which the display unit 6 is built into the general-purpose computer 100, the display unit 6 may be external. Also, both a built-in display unit 6 and an external display unit 6 may be included.

[0019] The operation unit 8 is a device with which the user inputs instructions to the general-purpose computer 100, and is typically one or more input devices such as a keyboard, a pointing device (such as a mouse), or a contact-sensing device (such as a touch panel). The keyboard may be a hardware keyboard or a software keyboard. The touch panel may be provided on the display unit 6, or may be in the form of a touchpad, such as those commonly found on notebook computers.

[0020] The communication interface (I / F) 20 is hardware that enables the general-purpose computer 100 to communicate with the external device 200 in accordance with a predetermined standard. The communication I / F 20 has a configuration according to the communication standard it supports, such as a connector that complies with a wired communication standard and a wireless transmitter / receiver that complies with a wireless communication standard. The communication I / F 20 may support multiple communication standards. There are no particular restrictions on the communication standards that the communication I / F 20 supports, but typical examples of wired communication standards include Ethernet (registered trademark) and USB, and typical examples of wireless communication standards include Bluetooth (registered trademark) and wireless LAN (IEEE802.11x).

[0021] There may be multiple external devices 200 with which the general-purpose computer 100 can communicate, but for convenience in the following description, the external device 200 is assumed to be a test data management device. The test data management device is a device that manages measurement data and analysis results obtained by various testing devices and analysis devices, such as an electrocardiograph (stationary electrocardiograph) that measures a resting electrocardiogram, a blood pressure pulse wave testing device, a respiratory function testing device, and an electrocardiogram analysis device, in association with subject information. The test data management device can manage data related to the same subject in association with the subject's identification information (subject ID), for example.

[0022] 1 shows only an electrocardiogram analyzer (general-purpose computer 100) and one stationary electrocardiograph 210, which are relevant to the description of the present invention, among the devices that can be connected to the external device 200 (test data management device). However, in reality, many more test devices can be connected to the external device 200.

[0023] A user (e.g., a technician) who uses automatic analysis of an electrocardiogram measured by a Holter electrocardiograph starts the automatic analysis application stored in storage device 10 by an operation method corresponding to the OS running on general-purpose computer 100. CPU 1 reads the automatic analysis application from storage device 10 into RAM 3 and executes it, causing general-purpose computer 100 to function as an electrocardiogram analyzer. Hereinafter, general-purpose computer 100 functioning as an electrocardiogram analyzer will be referred to as electrocardiogram analyzer 100.

[0024] Next, among the operations of the electrocardiogram analyzer 100 that are realized by the CPU 1 executing the automatic analysis application, operations related to preparation for long-term electrocardiogram measurement will be described with reference to the flowchart shown in FIG.

[0025] In S201, when the automatic analysis application is launched, the CPU 1 determines whether or not communication with a predetermined external device 200 (here, a test data management device) is possible. The CPU 1 can determine whether or not communication with the predetermined external device 200 is possible by performing a predetermined operation, such as sending a detection command for the predetermined external device 200 via the communication I / F 20. If it is determined that communication with the predetermined external device 200 is possible, the CPU 1 executes S203, and if not, executes S225. The processing from S225 onwards corresponds to the previous pre-registration operation.

[0026] In S203, the CPU 1 displays a pre-registration screen and enables a 12-lead electrocardiograph data reference button (hereinafter simply referred to as a 12-lead reference button) included in the pre-registration screen. An example of the pre-registration screen 300 is shown in FIG.

[0027] The pre-registration screen 300 is a screen on which a pre-registration function to be executed before a Holter electrocardiogram is measured can be executed. For example, the CPU 1 displays the pre-registration screen 300 in response to detecting a predetermined operation while a main screen, which is displayed as an initial screen after a user successfully logs in to an automatic analysis application, is being displayed. The CPU 1 can also display the pre-registration screen 300 in response to any other condition.

[0028] The pre-registration screen 300 has a subject attribute tab 301 and a recorder setting tab 302, and the subject attribute screen and recorder setting screen can be switched between by selecting the tab. Fig. 3 shows the state in which the subject attribute tab 301 is selected. Operations on GUI parts such as tabs and buttons included in the display screen may be performed by, for example, touching the operation unit 8 or clicking the mouse.

[0029] The subject attribute screen allows input of information such as information about the subject, the person in charge at the medical institution, and the purpose of Holter measurement. If communication with the test data management device is possible, inputting a subject ID, which is the subject's identification information, into input field 303 enables subject attribute acquisition button 304. When operation of subject attribute acquisition button 304 is detected, CPU1 transmits an information request including the subject ID to external device 200. CPU1 can automatically input (reflect) the subject information received from external device 200 in response to the request into the subject attribute screen.

[0030] The registration information selection area 305 is an area for selecting the type of information to be pre-registered. Here, subject attributes (subject information) and recorder settings can be selected arbitrarily. However, depending on the model of Holter electrocardiograph, some models can use pre-registered recorder settings and some cannot. Therefore, the default setting is unselected. Furthermore, if the model of recorder to be used for Holter measurement, which is set on the recorder setting screen, cannot use pre-registered recorder settings, the recorder settings cannot be selected. On the other hand, subject attributes are basically pre-registered regardless of the model, so the default setting is selected.

[0031] When CPU 1 detects operation of write button 306, it executes a pre-registration operation. That is, CPU 1 records the information input on pre-registration screen 300 as pre-registration information in memory card 4 or in a recording medium of the Holter electrocardiograph communicably connected via communication I / F 20, depending on the selection state of registration information selection area 305.

[0032] When the CPU 1 detects the operation of the file deletion button 307, it deletes the test data and pre-registration information recorded on the pre-registration destination recording medium. The file deletion button 307 is a button for deleting unnecessary data before pre-registration so that test data for multiple subjects is not mixed together.

[0033] The 12-lead reference button 308 is a button for referencing the standard 12-lead electrocardiogram data measured at rest from the test data registered in the external device 200 in association with the subject ID entered in the input field 303.

[0034] In S205, the CPU 1 determines whether or not operation of the 12-Lead Reference button 308 on the pre-registration screen 300 has been detected. If it is determined that operation of the 12-Lead Reference button has been detected, the CPU 1 executes S207; if not, the CPU 1 executes S225. If operation on another button or menu has been detected, the CPU 1 executes an operation corresponding to the button or menu on which the operation has been detected, and then executes S225. The operations corresponding to operations on GUI elements other than the 12-Lead Reference button 308 on the pre-registration screen 300 are as described above.

[0035] In S207, the CPU 1 transmits a data search request including the subject ID entered in the input field 303 of the pre-registration screen 300 and sender information (such as address and identification information) to the external device 200 via the communication I / F 20. Here, it is assumed that the test data management device, which is the external device 200, determines the type of data to be transmitted and received depending on the type of requesting device. That is, if the requesting device is an electrocardiogram analysis device, the test data management device determines that the long-term electrocardiogram data measured by a Holter electrocardiograph is the data to be transmitted and received. This is because, in general, testing devices cannot correctly handle data measured by other types of testing devices.

[0036] Therefore, in S207, the CPU 1 transmits to the external device 200 a data search request indicating that the requesting device is not an electrocardiogram analyzer but an electrocardiograph (fixed electrocardiograph) for measuring a resting electrocardiogram. For example, if the data search request includes the type of device, the CPU 1 transmits a data search request including the type of fixed electrocardiograph. Alternatively, if the data format of the data search request differs depending on the testing device, the CPU 1 transmits a data search request having a data format transmitted by a fixed electrocardiograph. These are merely examples, and any other method can be used that allows the external device 200 to recognize the data search request transmitted by the electrocardiogram analysis device 100 as a data search request from a fixed electrocardiograph.

[0037] In this way, the electrocardiogram analysis device 100 behaves as a fixed electrocardiograph with respect to the external device 200 as needed, which has the advantage that there is no need to change the processing of the external device 200. On the other hand, if the external device 200 determines the data type specified in the request as the target of transmission and reception, rather than the type of device that sent the request, there is no need for the electrocardiogram analysis device 100 to behave as a fixed electrocardiograph with respect to the external device 200. In this case, the CPU 1 may transmit to the external device 200 a data search request that specifies resting electrocardiogram data as the search target, for example, together with identification information of the device that sent the request.

[0038] When the external device 200 receives a data search request from the electrocardiogram analysis device 100 acting as a stationary electrocardiograph, it searches for test data stored in the internal and / or external storage device using the subject ID included in the data search request. It then determines whether test data measured by the stationary electrocardiograph exists for the subject ID. The external device 200 can determine the type of test data based on, for example, the file name, extension, or information included in the file header, but other methods may also be used.

[0039] The test data measured by the stationary electrocardiograph includes subject information, data from the subject's standard 12-lead electrocardiogram at rest, and parameters obtained by analyzing the data. The subject information may be, for example, the subject's ID, name, age, and gender. The parameters may be, for example, heart rate (HR), RR interval, PR interval, QRS height, QT interval length, and QTS axis deviation (°). The types of parameters may vary depending on the model of the electrocardiograph.

[0040] Stationary electrocardiograms basically measure standard 12-lead electrocardiograms, and because they are designed to be taken while the subject is at rest, the quality of the electrocardiograms is high. Furthermore, because the measurement time is short (about 10 seconds), the sampling frequency is higher than with Holter electrocardiograms, allowing for the capture of finer waveform characteristics. Therefore, not only is the waveform information more detailed, but the number and accuracy of the parameters obtained are also superior to those of long-term electrocardiograms measured with Holter electrocardiograms.

[0041] Although some Holter monitors are capable of recording standard 12-lead ECGs, the reality is that standard 12-lead ECGs, which require a large number of electrodes to be attached for long-term continuous measurement while going about one's daily life, are rarely used. Even if standard 12-lead ECGs are measured with a Holter monitor, the sampling frequency is lower than that of stationary ECGs in order to achieve long-term recording. Furthermore, because they are susceptible to noise and changes in electrode attachment during measurement, it is not possible to obtain the same variety and precision of parameters as stationary ECGs.

[0042] Due to these differences in measurement environment and measurement method, the standard 12-lead electrocardiogram measured with a Holter monitor and the standard 12-lead electrocardiogram at rest measured with a stationary electrocardiogram are completely different in nature, and basically the two cannot be used interchangeably. In view of this technical background, in this embodiment, an operation is performed to obtain a standard 12-lead electrocardiogram measured with a stationary electrocardiogram, rather than a standard 12-lead electrocardiogram measured with a Holter monitor.

[0043] The external device 200 transmits to the electrocardiogram analysis device 100 the search results for test data measured by a stationary electrocardiograph for the subject ID included in the data search request. The search results may be a list of test data recording dates and times (e.g., measurement start dates and times). Note that if the search results in only one relevant test data, the external device 200 may start transmitting the relevant test data as a search result. Note that the operation of the external device 200 in response to the search results is merely an example. As long as the electrocardiogram analysis device 100 can acquire test data of a standard 12-lead electrocardiogram at rest for a specific subject from the external device 200, the details of the interaction with the external device 200 and the operation of the external device 200 do not affect the present invention.

[0044] In S209, when the CPU 1 receives the search results from the external device 200 via the communication I / F 20, it checks the search results. If the list included in the search results does not include information on the test data, the CPU 1 recognizes that the corresponding test data does not exist and executes S225. On the other hand, if the list included in the search results includes information on one or more test data, the CPU 1 executes S211. Note that if there is only one test data corresponding to the subject ID and therefore the corresponding test data has been sent from the external device 200 as a search result, the CPU 1 proceeds to S215.

[0045] In S211, the CPU 1 determines whether the list included in the search result contains information on multiple test data sets. If it is determined that the list contains information on multiple test data sets, the CPU 1 executes S213, and if it is determined that the list contains information on one test data set, the CPU 1 executes S215.

[0046] In S213, the CPU 1 uses the information contained in the list to display a selection screen 500 as shown in FIG. 5 on the display unit 6. The selection screen 500 includes a data number, a subject's ID, and a list 501 of test data found by the search (test data measured with a stationary electrocardiograph). The list 501 is configured to allow selection for each data item. The user (technologist) can select the test data to be acquired by selecting it on the list 501 through operation of the operation unit 8 and operating the OK button 502 to select the desired data. On the other hand, if the user wishes to cancel viewing the test data, he or she operates the cancel button 503. When the cancel button 503 is operated, the CPU 1 closes the selection screen 500 and executes S225.

[0047] When an operation on the OK button 502 on the selection screen 500 is detected, the CPU 1 acquires information on the data selected in the list 501, clears the selection screen 500, and then executes S215.

[0048] In S215, the CPU 1 acquires the test data from the external device 200. The test data can be acquired by any method. For example, the CPU 1 transmits a transmission request to the external device 200, including information that can identify the test data (for example, a data number in a list included in the search results or a recording date and time). When the external device 200 receives the transmission request, it reads out the test data specified in the transmission request and transmits it to the requesting electrocardiogram analysis device 100. This allows the electrocardiogram analysis device 100 to acquire the requested test data. The CPU 1 stores the test data received via the communication I / F 20 in the RAM 3 and / or the storage device 10. Note that if the test data has been received at the stage of S209, the CPU 1 stores the received test data in the RAM 3 and / or the storage device 10 without transmitting a new transmission request to the external device 200 in S215.

[0049] In S219, the CPU 1 uses the measurement data and parameters included in the test data to display a reference screen that displays a 12-lead electrocardiogram, for example, separately from the pre-registration screen 300. An example of the reference screen 400 is shown in FIG.

[0050] The reference screen 400 has a parameter area 401, a waveform area 407, a sensitivity adjustment area 405, and a close button 403. The parameter area 401 is an area that displays the test date and time and various parameters obtained by electrocardiogram analysis included in the test data. The waveform area 407 is an area that displays a standard 12-lead electrocardiogram in a format similar to a printout from a stationary electrocardiograph. The sensitivity adjustment area 405 is an area that sets the sensitivity (magnification) of the standard 12-lead electrocardiogram displayed in the waveform area 407. Here, a radio button is provided for each sensitivity, and the user changes the sensitivity of the electrocardiogram by selecting the radio button corresponding to the desired sensitivity. However, the sensitivity may be selected using any other method, such as a pull-down menu.

[0051] In the initial state, the CPU 1 generates the waveform area 407 at a predetermined sensitivity (here, ×1). When another sensitivity is selected in the sensitivity adjustment area 405, the changed sensitivity is reflected in the waveform area 407. In this embodiment, the test data is acquired from the external device 200, and the CPU 1 generates (draws) the reference screen, so that the sensitivity of the electrocardiogram displayed in the waveform area 407 can be dynamically changed.

[0052] The user (technologist) can obtain useful information for preparing a Holter ECG measurement for the subject from the standard 12-lead ECG measured at rest and parameters based on the analysis.

[0053] For example, when measuring a Holter ECG from a standard 12-lead ECG, the user can accurately determine which lead is appropriate to measure from among the leads commonly measured with a Holter ECG, such as NASA, CM5, CC5, CM1, CM2, and CM3. Furthermore, the user can set the settings of the Holter ECG, such as the time constant and sensitivity used during measurement, and whether pacemaker detection is required, to appropriate values ​​for the subject. The settings of the Holter ECG may be set / changed by the user directly operating the Holter ECG, or, if the Holter ECG can be set using pre-registration information, the pre-registration information may include the setting values.

[0054] If the test data includes comments entered by a medical technician or comments from a doctor who interpreted the electrocardiogram, these comments can be displayed on the reference screen 400 to further improve the conditions and settings for Holter electrocardiogram measurement. The user uses the reference screen 400 to determine the leads to be measured by the Holter electrocardiogram and, if necessary, to determine the settings to be included in the pre-registration.

[0055] In S221, the CPU 1 determines whether the close button 403 on the reference screen 400 has been operated, and if it is determined that it has been operated, executes S223, and if it is not determined that it has been operated, executes S221 repeatedly. Here, it is assumed that the pre-registration screen 300 cannot be operated unless the reference screen 400 is closed.

[0056] In S223, the CPU 1 closes the reference screen 400 and executes S225. In S225, the CPU 1 determines whether or not a pre-registration execution operation (operation of the pre-registration execution button) has been performed on the pre-registration screen 300, and if it is determined that the operation has been performed, it executes S227, and if not, it executes S201.

[0057] In S227, the CPU 1 records the pre-registration information in the memory card 4 or in a recording medium of the Holter electrocardiograph communicably connected via the communication I / F 20, and ends the series of operations shown in FIG.

[0058] In this embodiment, an example has been described in which an electrocardiogram measured at rest is referred to in the preparation operation before measuring a long-term electrocardiogram. However, referring to a resting electrocardiogram is useful not only during the preparation operation. For example, after measuring a long-term electrocardiogram, by referring to the resting electrocardiogram when interpreting the automatic analysis results, information useful for interpreting the long-term electrocardiogram can be obtained.

[0059] As described above, according to this embodiment, an electrocardiogram analyzer for analyzing long-term electrocardiogram data provides a function for acquiring and referencing resting electrocardiogram data previously measured for a subject from an external device connected via communication, thereby enabling a user to make more appropriate decisions regarding settings for measuring a long-term electrocardiogram of the subject and more appropriately evaluate the results of automatic analysis of the measurement data.

[0060] Furthermore, when acquiring resting electrocardiogram data from an external device, the electrocardiogram analysis device of this embodiment can behave as a stationary electrocardiograph with respect to the external device. Therefore, even if the external device is configured to provide measurement data only to the same type of device as the device that measured the data, the resting electrocardiogram data can be acquired. Furthermore, there is no need to change the operation of the external device.

[0061] (Other embodiments) The present invention can also be implemented as a program that causes a computer to function as the electrocardiogram analyzer described in the above embodiment. Furthermore, the present invention is not limited to the content of the above embodiment, and various changes and modifications can be made without departing from the spirit and scope of the invention. Therefore, the following claims are appended to clarify the scope of the invention. [Explanation of symbols]
