Description

  The present invention relates to a biological waveform display system, a biological waveform display method, and a display device, and more particularly to a method for efficiently displaying a biological waveform during diagnosis.

  There is an electrocardiogram examination as a representative example of a method of using a subject's biological waveform. The electrocardiogram examination is used for diagnosis of arrhythmia and ischemic heart diseases such as angina pectoris and myocardial infarction. The ECG test includes a test (typically a 12-lead ECG test) that is performed in a hospital or the like within a short period of time, and a test that continuously measures the ECG waveform while conducting daily life ( A typical example is Holter ECG).

  By the way, when an electrocardiographic waveform of an arrhythmia with low occurrence frequency is to be measured, it may not be measured by any of the above examinations. In such a case, it has been proposed that an event-type electrocardiogram is useful.

  Event-type electrocardiogram is a test subject who carries a small measurement device and lives daily for a longer period (for example, about 2 weeks to 1 month) than Holter electrocardiogram. The electrocardiographic waveform is measured by the subject's own operation at a predetermined timing (for example, after getting up or before going to bed). Each of the ECG waveforms measured by the event-type ECG test is several tens of seconds to several minutes, but the total number of ECG waveforms measured during the test period is often several hundred. Absent. Therefore, it is not realistic for a doctor to check all the electrocardiogram waveforms measured at the time of diagnosis.

  On the other hand, a considerable number of electrocardiographic waveforms measured are irrelevant to arrhythmia and do not require confirmation by a doctor. In addition, the subject may measure the electrocardiographic waveform a plurality of times within the same arrhythmia period. In such a case, the measured electrocardiographic waveform becomes redundant.

Therefore, Japanese Patent Application Laid-Open No. 2007-20799 (Patent Document 1) is an analysis report that presents an analysis result of an electrocardiogram, and is an area that presents information on an abnormal state estimated from the analysis result. What has the area | region with which the position in the inside and severity were associated is disclosed.

  FIG. 9 is a diagram showing a display example after completion of measurement on display unit 148 of portable electrocardiograph 100 according to the present embodiment.

  Referring to FIG. 9, when the measurement of the electrocardiogram waveform is completed, CPU 154 displays “Yes” selection area 170 a and “No” selection area 170 b together with a message “Is there a subjective symptom?”. The selection areas 170a and 170b are configured to be selectable by the subject operating the operation unit 140 (FIG. 6). Here, when the subject selects the “Yes” selection region 170a and operates the determination button 144, the CPU 154 functioning as the input unit 154a accepts “the subject has a subjective symptom” as the state value of the subject. On the other hand, when the subject selects the “No” selection area 170b and operates the determination button 144, the CPU 154 functioning as the input unit 154a receives “no subjective symptom” as the state value of the subject.

Instead of the display example shown in FIG. 9, subjective symptoms may be selected in more detail.
FIG. 10 is a diagram showing another form of the display example after completion of measurement in display unit 148 of portable electrocardiograph 100 according to the present embodiment. Referring to FIG. 10, when the measurement of the electrocardiogram waveform is completed, CPU 154 indicates “please hurt”, “pounding”, “others”, “none” along with the message “Please select the current subjective symptom”. The selection areas 172a to 172d are displayed so that any one of the four items can be selected. The selection regions 172a to 172d are configured to be selectable by the subject operating the operation unit 140 (FIG. 6).

  Here, when the subject selects any of the selection regions 172a to 172c, the CPU 154 functioning as the input unit 154a accepts “with subjective symptom” as the state value of the subject, and sets the type of subjective symptom corresponding to each selection. Accept. On the other hand, when the subject selects the selection region 172d, the CPU 154 functioning as the input unit 154a accepts “no subjective symptom” as the state value of the subject.

More specifically, the CPU 154 functioning as the type discriminating unit 154b discriminates the type information of the electrocardiographic waveform data by extracting characteristic time changes appearing in the electrocardiographic waveform data stored in the RAM 155b.

  FIG. 11 is a diagram for describing classification processing of electrocardiographic waveform data type information in portable electrocardiograph 100 according to the present embodiment. 11A shows the waveform of the biological signal (electric signal) detected by the electrode unit 120, and FIG. 11B shows the waveform after the biological signal shown in FIG. 11A is filtered. .

  Referring to FIG. 11, the CPU 154 functioning as the type determination unit 154 b corresponds to a kind of low-pass filter (LPF) with respect to the biological signal detected by the electrode unit 120 as shown in FIG. The low frequency component is extracted by performing filtering processing. Then, a time waveform as shown in FIG. Furthermore, the CPU 154 extracts a component exceeding a predetermined threshold level Th from the time waveform shown in FIG. 11B as an “R wave” component. As described above, the CPU 154 functioning as the type determination unit 154 b extracts a characteristic temporal change that appears in the biological signal detected by the electrode unit 120.

  Further, based on the R-wave component, the CPU 154, for example, includes five types of abnormal items such as “tachycardia”, “bradycardia”, “RR interval irregularity”, “cardiac pause”, and “ventricular premature contraction”. Determine the information. The type information is not limited to these, and other items may be added. If none of the types is applicable, it is determined that the corresponding electrocardiographic waveform is normal.

  Here, the types of the five items will be briefly described. In general, “tachycardia” means that the heart rate is 100 times or more per minute, and “bradycardia” means that the heart rate is 50 times or less per minute. This “tachycardia” or “bradycardia” is determined based on the wave interval 180 of the R wave shown in FIG. “RR interval irregularity” means that the R wave interval is irregular, for example, the rhythm of the R wave is lost or one beat is lost. This “RR interval irregularity” is determined based on the R wave interval 180 shown in FIG. “Cardiac pause”, also referred to as “pause”, means that the heart is temporarily inactive. This “cardiac pause” is determined based on the length of the period 182 in which the R wave shown in FIG. 11B is not detected. “Ventricular extrasystole” is also referred to as “VPC (Ventricular Premature Contraction)” and refers to ectopic excitation generated from the ventricle of the heart. This “ventricular premature contraction” is determined based on the size of the width (QRS width) 184 of the triangle forming the R wave peak shown in FIG.

  The CPU 154 functioning as the type discriminating unit 154b discriminates the type information for each measurement of the electrocardiogram waveform by the type information discriminating process as described above.

  Note that the processes of steps S104 and S106 described above and the process of step S108 may be performed in parallel or in series. In the case of serial processing, the execution order is not limited.

  Referring to FIGS. 6 and 7 again, when the state value from the subject and the type information of the electrocardiogram waveform data are acquired, the CPU 154 functioning as the attribute information adding unit 154c stores these information as attribute information in the RAM 155b. After being added to the stored electrocardiographic waveform data (step S110), it is stored in the nonvolatile memory 155c (step S112). More specifically, this attribute information is added to the electrocardiographic waveform data as header information. Then, the measurement process of the electrocardiographic waveform in the portable electrocardiograph 100 ends.

  The extraction unit 211a and the alignment unit 211d determine the electrocardiographic waveform data to be displayed on the monitor unit 220 from the electrocardiographic waveform data 280A stored in the fixed disk 213 according to the conditions set by the user. .

  More specifically, the extraction unit 211a refers to the electrocardiographic waveform data 280A stored in the fixed disk 213, and extracts the attribute information that satisfies the predetermined extraction condition to be a display target. ECG waveform data is determined. In addition, the extraction unit 211a displays an extraction condition setting screen on which at least one extraction condition can be set on the monitor unit 220, and among the attribute information added to the electrocardiogram waveform data 280A, via the extraction condition setting screen. It is determined whether or not there is one that satisfies the extraction condition set by the user. When attribute information satisfying the set extraction condition is found, electrocardiographic waveform data corresponding to the attribute information is extracted. Then, the extraction unit 211a outputs a command for displaying the extracted electrocardiographic waveform data on the monitor unit 220 to the display data generation unit 211c.

  On the other hand, the alignment unit 211d refers to the electrocardiogram waveform data 280A stored in the fixed disk 213, and sorts the electrocardiogram waveform data 280A according to the alignment condition based on the added attribute information. Determine ECG waveform data. In addition, the alignment unit 211d displays an alignment condition setting screen on which at least one alignment condition can be set on the monitor unit 220, and displays on the monitor unit 220 according to the alignment condition set by the user via the alignment condition setting screen. A rearrangement process is performed on the electrocardiogram waveform.

  The extraction unit 211a and the alignment unit 211d may cooperate to determine electrocardiographic waveform data to be displayed on the monitor unit 220. In this case, for example, the alignment unit 211d may perform the sorting process only on the electrocardiographic waveform data extracted by the extraction unit 211a.

  The read information adding unit 211b adds read information indicating read / unread to each of the electrocardiographic waveform data 280A stored in the fixed disk 213 in response to a user operation. Specifically, the already-read information adding unit 211b indicates that “read” is performed on the electrocardiogram waveform data that matches the extraction condition set by the user or the electrocardiogram waveform data displayed to the user. The read information shown is added. The read information of the electrocardiographic waveform data 280A immediately after being acquired from the nonvolatile memory 155c is “unread”.

  As will be described later, the extraction unit 211a changes the display mode of the electrocardiographic waveform displayed on the monitor unit 220 based on the already-read information.

  The display data generation unit 211c generates data for displaying a predetermined image on the monitor unit 220 in accordance with instructions from the extraction unit 211a, the alignment unit 211d, and the read information addition unit 211b, and outputs the data to the monitor unit 220 To do. The display data generation unit 211c may be configured with a graphic card that is dedicated hardware.

  FIG. 14 is a diagram showing a data structure of electrocardiographic waveform data in portable electrocardiograph 100 and display device 200 according to the present embodiment.

  14A shows the data structure of the electrocardiogram waveform data 280 stored in the portable electrocardiograph 100, and FIG. 14B shows the data structure of the electrocardiogram waveform data 280A stored in the display device 200. Indicates.

  Referring to FIG. 14A, each of the electrocardiographic waveform data 280 stored in the nonvolatile memory 155c includes, for example, “ID information”, “recording date / time”, “subjective symptoms”, “normal / abnormal information”. , Five fields 281 to 285 of “waveform data”. The contents of each field are outlined. The “ID information” field 281 stores an identification number for specifying each electrocardiographic waveform data, and the “recording date” field 282 contains the measurement start date and time of each electrocardiographic waveform data. And information such as the measurement period. The “subjective symptom” field 283 shows information on the presence or absence of the subjective symptom (“with subjective symptom” or “no subjective symptom”) input by the subject according to the screen shown in FIG. 9, or in addition to that shown in FIG. According to the screen, the “type of subjective symptom” input by the subject is stored. The “normal / abnormal information” field 284 stores the type information determined by the determination processing as shown in FIG.

  On the other hand, for the electrocardiogram waveform data 280A stored in the fixed disk 213, as shown in FIG. 14B, the “read flag” and “ Two fields 286 and 287 of “display attributes” are further added. The “read flag” field 286 stores the read information added by the read information adding unit 211b. Further, the “display attribute” field 287 stores information on a display method and the like when displaying the electrocardiogram waveform data on the monitor unit 220.

(Extraction process and display process)
Next, with reference to FIG. 15, a processing procedure in the case of extracting and displaying electrocardiographic waveform data satisfying a predetermined extraction condition in display device 200 according to the present embodiment will be described.

  FIG. 15 is a flowchart showing a processing procedure related to extraction and display of an electrocardiographic waveform in display device 200 according to the present embodiment.

  Referring to FIGS. 13 and 15, first, when the nonvolatile memory 155c is attached, the interface unit 216 reads the electrocardiographic waveform data 280 from the non-volatile memory 155c and stores the electrocardiographic waveform data 280A on the fixed disk 213. (Step S200). Subsequently, the CPU 211 functioning as the extraction unit 211a causes the monitor unit 220 to display an extraction condition setting screen on which at least one extraction condition can be set (step S202). The CPU 211 receives the extraction condition set by the user via the extraction condition setting screen (step S204), and the attribute satisfying the set extraction condition in the electrocardiogram waveform data 280A stored in the fixed disk 213. ECG waveform data corresponding to the information is extracted (step S206).

  FIG. 16 is a diagram showing a display example of the extraction condition setting screen 250 displayed on the monitor unit 220 of the display device 200 according to the present embodiment.

  Referring to FIG. 16, as an example, CPU 211 has six items of “with subjective symptoms”, “tachycardia”, “bradycardia”, “irregular RR interval”, “cardiac pause”, and “ventricular premature contraction”. Is displayed on the monitor unit 220. On this extraction condition setting screen 250, the user selects at least one of the check boxes 251 to 256 corresponding to the desired extraction condition, and selects the execution button 257. Then, the extraction condition setting through the extraction condition setting screen 250 by the user is completed. When the user selects the cancel button 258, the extraction condition setting process is interrupted.

  Referring to FIGS. 13 and 15 again, CPU 211 functioning as extraction unit 211a displays an electrocardiogram waveform on monitor unit 220 based on the extracted electrocardiogram waveform data (step S208). At this time, the CPU 211 displays at least one electrocardiographic waveform data on the same screen, and performs cardiac processing according to the value of the “read flag” field 286 (FIG. 14) corresponding to each of the extracted electrocardiographic waveform data. The display form of the radio wave type is changed.

  FIG. 17 is a diagram showing a display example of the electrocardiogram waveform display screen 260 displayed on the monitor unit 220 of the display device 200 according to the present embodiment.

  Referring to FIG. 17, CPU 211 causes monitor unit 220 to display an electrocardiogram waveform display screen 260 including four electrocardiogram waveforms 261 to 264 extracted as an example. These electrocardiographic waveforms 261 to 264 are drawn by plotting data stored in the “waveform data” field 285 (FIG. 14) of the corresponding electrocardiographic waveform data 280. The time axes of the electrocardiographic waveforms 261 to 264 are preferably the same scale.

  In addition, the CPU 211 displays measurement information 265 and 266 in correspondence with the electrocardiographic waveforms 261 to 264. The measurement information 265 and 266 is displayed based on data stored in the “recorded date” field 282 and the “read flag” field 286 of the corresponding electrocardiogram waveform data 280. In particular, the CPU 211 changes the display mode according to the value (“read” or “unread”) stored in the “read flag” field 286 (FIG. 14). Specifically, when a value indicating “read” is stored in the “read flag” field 286, the CPU 211 displays the font using a relatively thin font as shown in the measurement information 266. On the other hand, when a value indicating “unread” is stored in the “read flag” field 286, the display is performed using a relatively thick font as shown in the measurement information 265. Thereby, the user can grasp at a glance whether or not the displayed electrocardiogram has been confirmed in the past. Therefore, since it is possible to avoid checking the electrocardiogram waveform in duplicate, diagnosis can be performed more efficiently.

  Instead of changing the font type according to “read” and “unread”, the font color (for example, “black” and “red”) may be changed. Further, switching between “always display” and “blinking display (blink)”, presence / absence of “underline”, and the like may be changed.

  The electrocardiogram waveform display screen 260 is provided with a check box (Selected) 267 in association with each electrocardiogram waveform. The check box 267 is configured such that the user can arbitrarily check the operation by operating the keyboard 230, the mouse 240, or the like. Then, as described later, the CPU 211 changes the value of the “read flag” field 286 of the electrocardiogram waveform data 280A corresponding to the checked check box 267 to a value indicating “read”. When the electrocardiogram waveform subjected to this operation is displayed after this operation, it is handled as an “read” electrocardiogram waveform.

  The display color of each of the electrocardiogram waveforms 261 to 264 displayed on the electrocardiogram waveform display screen 260 can be changed, and the setting value such as the display color is set in the “display attribute” of the electrocardiogram waveform data 280A. "Field 287 (FIG. 14).

  Referring to FIGS. 13 and 15 again, the CPU 211 functioning as the already-read information adding unit 211b sets the value of the “read flag” field 286 corresponding to the electrocardiogram waveform data that can be determined to be confirmed by the user as “read”. “Read” is set (step S210). Here, “the user confirms” corresponds to the case where the user checks the check box 267 (FIG. 17) as described above. Furthermore, regarding the electrocardiogram waveform that is extracted as an electrocardiogram waveform that satisfies the extraction condition specified by the user on the extraction condition setting screen 250 (FIG. 16) and displayed on the electrocardiogram waveform display screen 260, the “user confirms” You may treat it as a thing. Thereafter, the display processing of the electrocardiogram waveform in the display device 200 is terminated by the user operation.

  As described above, in addition to extracting those satisfying the extraction condition, the displayed electrocardiographic waveform may be changed according to a predetermined alignment condition.

(Alignment processing and display processing)
Next, with reference to FIG. 18, description will be given of a processing procedure in the case where display device 200 according to the present embodiment arranges ECG waveform data according to the alignment conditions and displays the ECG waveforms in the alignment order.

  FIG. 18 is a flowchart showing a processing procedure related to alignment and display of electrocardiographic waveforms in display device 200 according to the present embodiment.

  Referring to FIG. 13 and FIG. 18, first, when the nonvolatile memory 155c is attached, the interface unit 216 reads the electrocardiographic waveform data 280 from the nonvolatile memory 155c and stores the electrocardiographic waveform data 280A on the fixed disk 213. (Step S300). Subsequently, the CPU 211 functioning as the alignment unit 211d causes the monitor unit 220 to display an alignment condition setting screen in which alignment conditions can be set (step S302). Then, the CPU 211 receives the alignment conditions set by the user via the alignment condition setting screen (step S304), and aligns the electrocardiographic waveform data 280A stored in the fixed disk 213 according to the set alignment conditions (step). S306).

  FIG. 19 is a diagram showing a display example of the alignment condition setting screen 270 displayed on the monitor unit 220 of the display device 200 according to the present embodiment.

  Referring to FIG. 19, CPU 211 causes monitor unit 220 to display an alignment condition setting screen 270 that can arbitrarily select a key with a plurality of priorities defined. That is, on the alignment condition setting screen 270, a first priority key selection field 271, a second priority key selection field 273, and a third priority key selection field 275 are arranged. An alignment condition key for performing processing (sort processing) can be selected from a pull-down menu. This alignment condition key specifies an item used for the alignment process among the data included in the attribute information added to each ECG waveform data.

  More specifically, the user operates the keyboard 230 and the mouse 240 to set items to be set in each field (for example, “abnormal item”, “subjective symptom”, “recording date”, etc.). At this time, the user also selects toggle buttons 272, 274, 276 corresponding to each field. The toggle buttons 272, 274, and 276 perform the alignment process on the corresponding field items in “ascending order” or “descending order”. Here, “ascending order” means sorting in order from small value to large value, aiueo order, alphabetical order, etc. “descending order” means sorting in the reverse order of “ascending order”. To do.

  As described above, when the user sets desired conditions for the priority key selection fields 271, 273, 275 and the toggle buttons 272, 274, 276 and then selects the execution button 277, the CPU 211 performs the alignment process as the alignment unit 211d (step S306). Execute. When the user selects the cancel button 278, the alignment process is interrupted.

  As an example, an alignment process when an alignment condition as shown in FIG. 19 is set will be described. First, an alignment process focusing on “abnormal items” set in the first priority key selection field 271 is executed. That is, when the “abnormal item” includes five types of information such as “tachycardia”, “bradycardia”, “RR interval irregularity”, “cardiac pause”, and “ventricular extrasystole”. The electrocardiographic waveform data is sorted so that the identification information is “in ascending order”. As a result, the ECG waveform data having the same identification information is rearranged so as to be continuous.

  Next, an alignment process focusing on “subject symptoms” set in the second priority key selection field 273 is executed. That is, when the “subjective symptoms” include four items “chest pain”, “pounding”, “other”, and “none”, the subjective symptoms are set to “ascending order”. Rearranged. As a result, the ECG waveform data having the same items are rearranged so that the ECG waveform data groups having the same identification information are continuous.

  As a result of such sort processing, the monitor unit 220 displays an electrocardiogram waveform corresponding to electrocardiogram waveform data in which both “abnormal item” and “subjective symptom” have the same value. That is, in the monitor unit 220, for example, “tachycardia” is stored as “abnormal item”, and the electrocardiogram waveform corresponding to the electrocardiogram waveform data in which “chest is painful” is stored as “subjective symptom”. Will be displayed continuously.

  Referring to FIGS. 13 and 18 again, CPU 211 functioning as aligning unit 211d displays electrocardiographic waveforms on monitor unit 220 in the order of the aligned electrocardiographic waveform data (step S308). That is, the CPU 211 functioning as the aligning unit 211d outputs a command for displaying the electrocardiographic waveform data on the monitor unit 220 in the display order after sorting to the display data generating unit 211c. Further, the CPU 211 functioning as the read information adding unit 211b sets the value of the “read flag” field 286 corresponding to the electrocardiogram waveform data that can be determined to be confirmed by the user to “read” (step S310). Thereafter, the display processing of the electrocardiogram waveform in the display device 200 is terminated by the user operation.

  Since the processing and screen display in steps S308 and S310 are the same as those in steps S208 and S210 in FIG. 15 and FIG. 17, detailed description thereof will not be repeated.

  Furthermore, as an example of the processing procedure in the case where the extraction process of the electrocardiogram waveform data and the alignment process are performed on the electrocardiogram waveform after the extraction process are performed, in the flowchart shown in FIG. This corresponds to a flowchart in which steps S302 to S306 in FIG. 18 are inserted between step S206 and step S208.

  In the above-described embodiment, the case where an electrocardiogram waveform is measured is exemplified as a representative example of a biological waveform. However, the present invention is not particularly limited to an electrocardiographic waveform, and is a portable measurement that measures other biological signals. It is also applicable to the device.

  In the above-described embodiment, the electrocardiographic waveform display system SYS including the portable electrocardiograph 100 and the display device 200 has been described. However, all the functions of the electrocardiographic waveform system are performed by one portable heart. You may put together in the electrometer 100A.

  FIG. 19 is a functional block diagram showing a functional configuration of a portable electrocardiograph 100A (electrocardiographic waveform system) according to a modification of the embodiment of the present invention. As shown in FIG. 19, the functions of the extraction unit 211a, the read information addition unit 211b, the display data generation unit 211c, and the alignment unit 211d shown in FIG. 13 are added to the CPU 154 of the portable electrocardiograph 100A. Thus, one portable electrocardiograph 100A can function as an electrocardiographic waveform system.

  The program executed in each of the portable electrocardiograph 100 and the display device 200 is a program module provided as a part of a computer operating system (OS). It may be called at a timing to execute processing. In that case, the program itself does not include the module, and the process is executed in cooperation with the OS. A program that does not include such a module can also be included in the program according to the present invention.

  The program according to the present invention may be provided by being incorporated in a part of another program. Even in this case, the program itself does not include the module included in the other program, and the process is executed in cooperation with the other program. Such a program incorporated in another program can also be included in the program according to the present invention.

  The provided program product is installed in a program storage unit such as a hard disk and executed. Note that the program product includes the program itself and a storage medium in which the program is stored.

  According to the present embodiment, when the electrocardiographic waveform is detected by the portable electrocardiograph 100 and the electrocardiographic waveform is stored as electrocardiographic waveform data, a subjective state value (typical) input from the subject is used. Is added with attribute information including the presence or absence of subjective symptoms. On the other hand, on the display device 200 side, based on the attribute information added to the electrocardiogram waveform data, an electrocardiogram waveform that satisfies a predetermined extraction condition (for example, presence or absence of subjective symptoms) desired by a doctor who is a diagnostician or the like. Data can be easily extracted. Based on the electrocardiographic waveform data satisfying the predetermined extraction condition, the necessary electrocardiographic waveform is efficiently displayed. By such efficient extraction (selection) and display of an electrocardiographic waveform, diagnosis by a doctor or the like can be performed efficiently.

  Further, according to the present embodiment, since information indicating “read” or “unread” is added to each electrocardiogram waveform data, the display device 200 displays “read” or “read” for each electrocardiogram waveform. "Unread" can be displayed. As a result, a doctor who is a diagnostician can grasp at a glance whether or not the electrocardiogram waveform has already been confirmed, so the same electrocardiogram waveform is erroneously confirmed multiple times. You can avoid that. Therefore, even when a large number of electrocardiogram waveforms are measured, a diagnosis by a doctor or the like can be performed efficiently.
