In the present embodiment, it is assumed that the physician or the like on the receiving side can quickly and easily grasp the condition of the patient from the analysis data. The contents of such analysis data will be exemplified below. 5. Specific examples of analysis data

 Hereinafter, an example of the analysis data as the feature amount data according to the present invention will be described. The following information (1) to (3) can be used as the contents of the analysis data.

(1) Recognition value

 These are the extreme points of the waveforms such as the P, Q, R, S, T, and U waves, which are the components of the electrocardiogram waveform, as well as the waveform start and end points. In addition, ST points (for example, STj, ST1, ST2, etc.) can also be used as analysis data. Note that all of the recognition values may be used as analysis data. However, in consideration of traffic during communication, only part of the recognition values may be used as analysis data, or some of the recognition values may be used instead of some. The extracted data or the data obtained by averaging the recognition values for a certain period of time may be used as the analysis data.

 Here, FIG. 11 shows an example of an electrocardiogram used by the CPU 10 of the electrocardiogram data measuring and transmitting apparatus 100 when calculating these recognition values. As shown in FIG. 11, specifically, the CPU 10 performs R (R potential or R wave height) based on any of the P wave, Q wave, R wave, S wave, ST part, and T wave of the electrocardiogram. , T (T potential or T wave height), Q (Q potential or Q wave height), ST (ST level), QT (QT interval), RR (RR interval).

 (2) Analysis value

 An interval value or the like calculated from the position of the recognition value. Specifically, PR interval values, QRS interval values, QT interval values, QTc values obtained by correcting the QT interval values, and the like can also be used as analysis data.

 (3) Arrhythmia information

It is arrhythmia information estimated from the recognition value, analysis value, and the like. This arrhythmia information can generally be obtained by measuring the electrocardiogram with 12 leads. The specific example of the content of the analysis data has been described above. In the present embodiment, the ST point will be described as an example from the illustrated examples. Here, FIG. 10 shows a conceptual diagram of the relationship between the original waveform data recorded in the memory and the analysis data. The upper part of Fig. 10 shows the original waveform data, and the lower part shows the calculated and analyzed data (ST points) in a graph. As described above, in the present embodiment, both the original waveform data and the analysis data are stored in the ECG data. The evening measurement transmitting device 100 or the electrocardiogram data receiving device 300 will be associated and recorded in the memory.

 Note that the analysis data is not limited to the ST point, and other information described above may be used.Other information may be used if it is useful for diagnosing a patient's condition. it can. Further, the analysis data is not limited to a single piece of information, and may use a plurality of pieces of information described above.

 Depending on the patient's motion during the measurement of the original waveform data, noise having an abnormal period may be generated in the electrocardiogram waveform, and accurate analysis data that can be used for diagnosing a disease state may not be obtained in many cases. As a method of obtaining accurate analysis data by excluding such noises, for example, a technique disclosed in Japanese Patent Application Laid-Open No. 6-261871 may be used.

 The embodiments described below enable effective and efficient transmission and reception of electrocardiogram data for diagnosis of a disease state in emergency medicine. The requirement for such efficient transmission and reception of ECG data is mainly based on the technical premise that there is a certain limit on the transmission capacity used when transmitting and receiving ECG data. That is the reason. Therefore, in the embodiment, the total transmission capacity is divided into a transmission capacity for transmitting and receiving the original waveform data and a transmission capacity for transmitting and receiving the analysis data in order to transmit and receive necessary data preferentially. Is one of the technical features.

 6. Explanation of ECG data transmission / reception processing according to the first embodiment

In the first embodiment, analysis data is transmitted and received between the electrocardiogram data measurement and transmission device 100 and the electrocardiogram data reception device 300, and a transmission request of the original waveform data at a specified time during the transmission and reception is performed. An example of transmitting and receiving the original waveform data will be described. In emergency care, in order to make effective use of ECG data for diagnosis of pathological conditions, it is necessary to prioritize transmission and reception of necessary data. In the present embodiment, the analysis data is selected as the data to be transmitted / received with priority, thereby enabling the transmission / reception of the electrocardiogram data capable of promptly responding to emergency medical care requiring urgency. Communication between the electrocardiogram data transmission apparatus 100 and the electrocardiogram data reception apparatus 300 is via a telephone line. Hereinafter, the outline of the electrocardiogram data transmission / reception processing will be described with reference to FIG. 5, and then, the contents of the processing of each device will be described with reference to the flowchart of FIG.

 As shown in FIG. 5, the electrocardiogram data measuring and transmitting apparatus 100 generates the measured cardiac current as original waveform data packetized every 1 second (symbol 1), and analyzes the original waveform (symbol 1). In the embodiment, an ST point) is generated (symbol 2). The electrocardiogram data measurement and transmission device 100 transmits the generated analysis data in chronological order (symbol 3). The electrocardiogram data receiving device 300 records the received analysis data in order and displays it on the display 36 (symbol 4). If a doctor or the like who diagnoses the patient's condition while looking at the display 36 determines that he / she wants to check the original waveform data for a more detailed diagnosis of the condition, the user specifies the measurement time and requests transmission of the original waveform data. Yes (symbol 5). The electrocardiogram data measurement transmitter 100 transmits the original waveform data at the requested time.

(Symbol 6), the electrocardiogram data receiving apparatus 300 records the original waveform data and displays it on the display 36 (symbol 7).

 As described above, in this system, by displaying the analysis data to a doctor or the like in advance, it is possible to quickly diagnose a disease state, and further, it is possible to transmit and receive data at a time requested by the receiving side.

 Next, processing of each device according to the first embodiment will be described based on the flowchart of FIG. Here, electrocardiogram data is transmitted and received between the ECG data measurement and transmission device 100 provided in the ambulance carrying the patient and the ECG data reception device 300 provided in the ICU of the destination hospital. Here is an example. ECG data measurement transmitter 1

The CPUs 10 and 20 of the EC 0 perform measurement processing and transmission processing of the electrocardiogram data according to the flowchart of FIG. 6, and the CPU 30 of the electrocardiogram data receiving apparatus 300 transmits the electrocardiogram data according to the flowchart of FIG. Perform reception processing. The CPU 10 of the electrocardiogram data measurement and transmission device 100 measures the cardiac current via the ECG electrode 12 and the amplifier 13 attached to the patient's body (step S602). The CPU 10 automatically sets conditions for cardiac current measurement, for example, by judging the condition of the patient. As an automatic setting, for example, when the absolute value (that is, the measured value) of the data output from the AZD conversion 14 is small, the CPU 10 performs a predetermined operation (for example, n times) on the data value. To get a given absolute value, or E When the polarity of the output waveform is inverted because the CG electrode 12 is attached incorrectly, the process of the CPU 10 inverting the output waveform data corresponds to the case.

 The CPU 10 generates the original waveform data by packetizing the measured cardiac current as data for every one second of the measurement time (step S604), and furthermore, analyzes the generated original waveform-analysis data for each beat (this embodiment). Then, an ST point is generated (step S606). The CPU 10 converts the original waveform data into a bucket as data information for each measurement time of 1 second, and packetizes the analysis data for each original waveform-beat (step S608). In each packet, a transmission code, an ID for identifying a patient, etc., and measurement time data are recorded (see Fig. 4).

 The CPU 20 of the transmitting unit 4 records the ECG data transferred to the transmitting unit 4 via the communication device 17 in the memory 26, and transmits the untransmitted analysis data to the ECG data receiving apparatus 300 by the telephone line. Are transmitted in the order of measurement time series (step S610).

 The CPU 30 of the electrocardiogram data receiving apparatus 300 determines whether or not to receive the analysis data (step S650). If it is determined that the analysis data has been received, the CPU 30 records the received analysis data to the hard disk 34 or the memory 38. (Step S652). CPU 30 displays the received analysis data on display 36 (step S654). The CPU 30 determines via the keyboard 35 whether or not an operator (for example, a physician who will perform a treatment for a patient) inputs a request for original waveform data (step S656). When determining that there is no input request, the CPU 30 determines whether or not all the analysis data has been received (step S666), and if not, repeats the processing from step S650. Here, whether or not all ECG data has been received is determined by transmitting the final data as information when transmitting the final data to be transmitted from the transmitting side. What should I do?

If the CPU 30 determines in step S656 that a request for the original waveform data has been input, the CPU 30 transmits information on the requested time to the electrocardiogram data measurement and transmission device 100 as request information (step S658 ). The CPU 20 of the electrocardiogram data measuring and transmitting apparatus 100 determines whether or not the request information has been received (step S612). If it is determined that the request information has been received, the original waveform data at the requested time is output to the electrocardiogram data. It transmits to overnight receiver 300 (step S614). The CPU 30 determines whether or not to receive the original waveform data (step S660). If it is determined that the original waveform data has been received, the CPU 30 records the original waveform data (step S662), and displays the original waveform data on the display 36. (Step S664).

 Note that the CPU 30 receives both the analysis data and the original waveform data via the communication circuit 32, and it is necessary to identify both of them and record them on the hard disk 34 or the memory 38. As shown in FIG. 4, the CPU 30 discriminates the both based on the transmission code recorded in the header information of each bucket. Specifically, if the transmission code is "10", the CPU 30 recognizes that it is the original waveform data, while if the return code is "20", it recognizes the analysis data.

 In addition, since the CPU 30 needs to display both the analysis data and the original waveform data as a waveform screen (such as a graph) corresponding to the elapse of the measurement time, each data is a data corresponding to which measurement time. Need to be identified. The identification of the measurement time by the CPU 30 is also performed based on the “measurement date and time” recorded in the header information of each packet, as shown in FIG.

 The CPU 20 and the CPU 30 repeat the above processing until transmission / reception of all analysis data to be transmitted ends. If the CPU 30 of the electrocardiogram data receiving apparatus 300 determines that all the electrocardiogram data has been received (step S666), it transmits a reception completion signal to the electrocardiogram data measurement transmitting apparatus 100 (step S668), and The evening reception process ends. If the CPU 20 of the electrocardiogram data measurement / transmission device 100 determines in step S616 that the reception completion signal has been received, the CPU 20 ends the analysis data transmission process.

 Before starting the above transmission / reception processing, the capacity of the ECG data receiver 300 or the hard disk 34 or the memory 38 is determined to determine whether or not reception is possible. May be transmitted overnight.

Here, an example of a screen displayed on the display 36 of the electrocardiogram data receiving apparatus 300 is shown in FIG. Figure 7A is an example of the screen before the request for the original waveform data. Figure 7B shows It is an example of a screen after acquisition of the original waveform data at the requested time. In Fig. 7A, the upper and lower waveform diagrams are displayed. The upper waveform diagram shows the analysis waveforms (transition of ST points) in chronological order based on the received analysis data. The lower waveform diagram shows the electrocardiogram in chronological order based on the original waveform data. In the waveform diagram, the vertical axis represents the electrocardiogram (mV), and the horizontal axis represents time (minutes or seconds). In addition, the screen displays “ID” for identifying the patient, “Start time” indicating the time when the measurement was started, “Selection time” indicating the measurement time of the original waveform data requested by the operator, etc. ing. As shown in FIG. 7A, in this example, the operator has selected that time to request the original waveform data corresponding to the analysis data near “10 min” (see FIG. 6A). Corresponding to S656). Then, as shown in FIG. 7B, the original waveform data at that time is obtained (corresponding to steps S626 and S664 in FIG. 6). Note that the specification of the original waveform data is not limited to the case where the pointer is input at the selected time, as shown in Fig. 7, but it is possible to click a part of the analysis waveform or input the time in the column of the selected time. You may make it.

 7. Effects of the first embodiment

 According to the present embodiment, the operator of the electrocardiogram data receiving apparatus 300 can obtain analysis data (ST points) based on the feature amounts extracted by analyzing the original waveform data (step S in FIG. 6). 6 52). Here, the original waveform data includes information other than the minimum information for diagnosing a patient's condition, but the analysis data on the other hand extracts only the ST points of the waveform and obtains the status of the ST section. The information is limited to information that is effective for the judgment. Therefore, the data receiving side can easily diagnose a patient's condition based on, for example, a change in ST level.

The operator of the electrocardiogram data receiving apparatus 300 can grasp the ST point at a glance by displaying the analysis data on the display (see FIG. 6, step S654, FIG. 7A). While receiving the analysis data, it is possible to acquire any original waveform data that was the source of the analysis data (see steps S666 and Fig. 7B in Fig. 6). Therefore, the data receiving side can easily make a diagnosis of the patient's condition based on the ST point in advance, but if the diagnosis requires a more accurate diagnosis, the ST point can be used. An accurate diagnosis of the disease state is obtained by acquiring the original waveform data I can.

 Here, as a pathological diagnosis based on the ST point, for example, if the ST point is elevated, it can be determined that there is a possibility of myocardial infarction, pericarditis, myocarditis, dilated cardiomyopathy, etc.

If the ST point decreases, it can be determined that there is a possibility of ischemic heart disease, hypertension, valvular disease, congenital heart disease, cardiomyopathy, myocardial degeneration, cardiac hypertrophy, and the like. Taking the example of FIG. 7A described in the first embodiment as an example, the ST point, which is the analysis data, rises from around 1 O min, and the doctor who sees this changes the disease state around 1 O min. By presuming that there was a problem, and acquiring the original waveform data (see FIG. 7B, step S6664 in FIG. 6), it is possible to make a more accurate judgment of the pathological condition diagnosis.

 8. Explanation of ECG data overnight transmission / reception processing according to the second embodiment

 The second embodiment exemplifies a process of transmitting the original waveform data and the analysis data in parallel, whereby it is possible to preferentially transmit data necessary for emergency medical care determination. There is a difference between the second embodiment and the first embodiment in the method of data transmission processing by the electrocardiogram data measurement transmission device 100. However, the data reception processing by the electrocardiogram data receiving apparatus 300 is the same as that of the first embodiment. In addition, the electrocardiogram data receiving apparatus 300 receives the original waveform data during the analysis data receiving. If the request is made, the transmission and reception processing of the original waveform data is performed as in the first embodiment. Therefore, in the following description, only a process of transmitting original waveform data and analysis data in parallel, which is a difference between the second embodiment and the first embodiment, will be described as an example.

 Hereinafter, as a second embodiment, an outline of electrocardiogram data transmission / reception processing will be described with reference to FIG. 8, and then, the contents of processing of each device will be described with reference to the flowchart of FIG.

 In the electrocardiogram data transmission / reception processing of the second embodiment, for the electrocardiogram data currently being measured, while transmitting the original waveform data and the analysis data, in parallel with the transmission thereof, for the past electrocardiogram data, The content of the analysis data is to be transmitted preferentially so that changes in the disease state after the start of measurement can be determined quickly.

As shown in FIG. 8, the electrocardiogram data measuring and transmitting apparatus 100 first measures (A) the latest original waveform data and (B) analysis data corresponding to the original waveform while measuring the patient's cardiac current. , (C) The analysis data not yet transmitted from the start of measurement to the start of transmission Transmit each packet at the same time (symbol 1). That is, for the latest measured ECG data, both packets of the original waveform data and the analysis data are transmitted in chronological order after the transmission start time, and for the past ECG data, The packets of the analysis data are transmitted in chronological order. On the other hand, when receiving the data, the electrocardiogram data receiving apparatus 300 continuously displays the data on the display 36 as shown in FIG. On the display 36, the upper waveform diagram is a display based on the analysis data, and the lower waveform diagram is a display based on the original waveform data. The graphs indicated by A to C are based on the above data.

 After completion of transmission of all the packets in (C) above, that is, after completion of transmission of the analysis data until the start of transmission, the electrocardiogram data measurement and transmission apparatus 100 (A), (B), and (D) ) Simultaneously transmit each packet with the original waveform data that has not been transmitted from the start of measurement to the start of transmission (symbol 2). At this time, as shown on the display 36, all of the analysis data from the start of the measurement to the latest analysis data has been received.

 After the completion of transmission of all the packets in (D) above, that is, after the transmission of the original waveform data until the start of transmission, the electrocardiogram data measurement and transmission apparatus 100 simultaneously transmits the packets (A) and (B). Send (symbol 3). At this time, as shown on the display 36, all of the original waveform data has been received from the start of the measurement to the latest one. After that, the original waveform data and analysis data that have been measured and generated are continuously sent for 1 s and fec b.

 Thus, this system enables real-time pathological diagnosis by transmitting the latest electrocardiogram data (original waveform data and analysis data), and by prioritizing transmission of past analysis data, This makes it possible to quickly determine changes in the disease state after the start of measurement.

In the second embodiment, a maximum of three types of data are transmitted in parallel. However, in the present embodiment, this is because the electrocardiogram data overnight measurement transmitting device 100 and the electrocardiogram data overnight receiving device 300 This takes into account the transmission capacity of the communication between them. However, depending on the type of communication line, an embodiment in which four or more types of data are transmitted in parallel or only two types of data are transmitted in parallel can be adopted. In this embodiment, the order of parallel transmission is also described. The order is not limited to the example, and another order may be adopted. In any case,

In the second embodiment, as an example, a description will be given assuming that up to three types of packets can be transmitted in parallel under a general technical assumption that there is a certain limit on a transmission capacity used when transmitting and receiving electrocardiogram data. .

 Next, transmission processing according to the second embodiment will be described with reference to the flowchart in FIG. Here, only the process of transmitting the original waveform data and the analysis data in parallel, which is the difference between the second embodiment and the first embodiment, will be described as an example. The CPU 20 of the ECG measurement / transmission apparatus 100 performs the ECG data transmission process according to the flowchart of FIG. The transmission process is performed by a telephone line. The processing from generation of the original waveform data and generation of the analysis data to the packetization of each data is the same as that shown in steps S602, S604, S606, and S608 in FIG. The CPU 10 of the electrocardiogram data measurement and transmission device 100 measures the cardiac current, buckets the measured cardiac current as data for each measurement time of one second, generates original waveform data, and further generates the generated original waveform-beat. The analysis data (ST point in this embodiment) is generated for each time. The CPU 10 packetizes the original waveform data as data information for each measurement time of 1 second, and packetizes the analysis data for each original waveform-beat. Each bucket records a transmission code, an ID for identifying a patient, and measurement time data (see Fig. 4). After this processing, the CPU 10 continuously generates the original waveform data and the analysis data, and the electrocardiogram data is continuously transmitted to the transmission unit 4 via the communication devices 17 and 24 until the measurement is completed. Will be transferred. Then, the CPU 20 of the transmitting unit 4 transmits the continuously transferred electrocardiogram data by the following processing.

The CPU 20 of the transmission unit 4 records the ECG data transferred to the transmission unit 4 via the communication device 17 in the memory 26, and also stores the latest original waveform data and the latest original waveform data corresponding to the original waveform data. The analysis data and the untransmitted analysis data from the start of measurement to the start of transmission are transmitted in parallel in chronological order (step S910 in FIG. 9). The CPU 20 determines whether or not all of the analysis data up to the start of transmission has been transmitted (step S912), and if not all have been transmitted, repeats the processing from step S910 again. If the CPU 20 determines in step S912 that all of the analysis data up to the start of transmission has been transmitted, that is, it has determined that all analysis data buckets before the latest analysis data currently being transmitted have been transmitted. Then, the process of step S914 is performed. In step S914, the CPU 20 chronologically compares the latest original waveform data, the latest analysis data corresponding to the original waveform data, and the untransmitted original waveform data from the measurement start to the transmission start. They are transmitted in parallel in order (step S914).

The CPU 20 determines whether or not transmission of all of the original waveform data up to the start of transmission has been completed (step S916), and if not all have been transmitted, repeats the processing from step S914 again.

 If the CPU 20 determines in step S916 that all of the original waveform data up to the start of transmission has been transmitted, that is, all the original waveform data packets before the latest original waveform data currently being transmitted have been transmitted. If so, the processing of step 918 is performed. In step S918, the CPU 20 transmits the latest original waveform data and the latest analysis data corresponding to the original waveform data in parallel in chronological order. The CPU 20 determines whether all of the original waveform data and all of the analysis data in the memory 26 have been transmitted (step S920). If it is determined that all of the data has been transmitted, the transmission process ends.

 9. Effect of the second embodiment

 According to the present embodiment, the electrocardiogram data receiving apparatus 300 can simultaneously acquire not only the original waveform data but also the analysis data (ST point) extracted by analyzing the waveform (step S910 in FIG. 9). S 914, S 918). Therefore, the receiving side of the data can easily diagnose a patient's condition based on the analysis data, while a more detailed condition can be obtained based on the original waveform data based on the analysis data. Diagnosis can be made.

While the electrocardiogram data receiver 300 can acquire the analysis data in chronological order, it can acquire the original waveform or the analysis data currently being measured in real time (step S910 in FIG. 9). Therefore, the data receiving side can easily diagnose the patient's condition based on the analysis data, but can always perform the patient's condition diagnosis in real time. A transmission code for identifying both the original waveform data and the analysis data is recorded (see Fig. 4). Therefore, even when receiving the original waveform data and the analysis data in parallel, the electrocardiogram data receiving apparatus 300 identifies them based on the respective transmission codes, and separates them into the hard disk 34 or the memory as separate data. It can be recorded on 38 and played on the display 36.

 Time information indicating the measurement date and time is recorded in each of the original waveform data and the analysis data (see Fig. 4). Therefore, even when the electrocardiogram data receiving apparatus 300 receives the original waveform data or the analysis data irrespective of the time-series order, the electrocardiogram data receiving apparatus 300 converts the original waveform data or the analysis data into the time-series based on the respective time information. The data can be reproduced on the display 36 in order or recorded on the hard disk 34 or the memory 38 so that the data can be reproduced in chronological order. As a result, the electrocardiogram data measurement and transmission device 100 can transmit data in any order regardless of the data measurement order.

 10. Other Embodiments

As another embodiment, the CPU 20 of the electrocardiogram data measuring and transmitting apparatus 100 may transmit only analysis data indicating an abnormal value. At this time, as a method of determining that the analysis data is an abnormal value, for example, when an ST point is used as analysis data, an abnormal value is set when the variation width of the ST point is XmV or more. What should I do?

 In the first and second embodiments, as illustrated in FIG. 4, the ID, the measurement date and time, the data length, and the measurement data are packetized as electrocardiogram data, but other information may be recorded together. Good. For example, an “attribute code” may be added as information indicating the attribute of the electrocardiogram data to be transmitted. This attribute code records whether the electrocardiogram data is the latest data, past data, or data at a specified time when a transmission request is made. This allows the receiving side to quickly determine the attributes of the received ECG data.
