Description

[Detailed description of the invention] [Field of industrial application] The present invention is an electrocardiograph that measures the electrocardiogram signal of a subject, and analyzes the measured electrocardiogram signal to identify the corresponding finding among multiple types of findings. The present invention relates to a transmission-type or non-transmission-type electrocardiogram analysis device comprising an electrocardiogram analysis section that sends out analysis result data including the above, and a recording section that records the analysis results on a recording surface.

[Problems that conventional technology and ideas try to solve]

Various methods are well known for the classification of electrocardiograms, and the Minnesota Code in particular has been established as an objective classification standard that applies to any findings (results of knowledge about electrocardiogram waveforms used as diagnostic material), and is currently used as a classification standard. However, it has become the only international common standard. Arrhythmias are classified into a wide variety of findings, including ventricular tachycardia, supraventricular tachycardia, and others, and ventricular conduction disorders are classified into intraventricular block, complete left bundle branch block, and others. However, conventional electrocardiogram analysis devices based on such classification criteria only record findings and the like as text along with the identification data of the subject. Therefore, there was a drawback that it was difficult for non-specialists to understand the contents of the findings in detail.

In view of this point, it is an object of the present invention to provide an electrocardiogram analysis device that can more specifically report analysis results to non-specialist doctors or subjects.

[Means for solving problems]

In order to achieve this purpose, the present invention, as shown in FIG. an electrocardiogram analysis unit 2 that sends analysis result data including the name of the finding that corresponds to the finding;
A recording unit 3 that records analysis results on a recording paper, character data for a recorded sentence on the recording paper, heart pattern data of fewer types than the assumed plurality of types for displaying the heart as a pattern, and the displayed heart pattern. A memory 4 that independently stores mark data indicating the location of findings in the internal memory 4 and a built-in CPU decode the analysis result data, and record characters of the finding name and the combination of the cardiac pattern and mark corresponding to this finding name. The apparatus includes a recording control section 5 that makes a judgment, reads the memory, and causes the recording section to record the finding name and the combination of the heart pattern and the mark at a predetermined position on the recording sheet. In other words, the memory 4 has not only a character data area 4a, but also data areas 4b ₁ to 4b _o of heart patterns and data areas 4c ₁ to 4c _o of marks indicating findings in this heart pattern, and a large number N The number n (n<N) required to mark and indicate the areas of findings across the anterior wall, posterior wall, left and right side walls, etc. of the heart that have been identified among the findings.
It is now possible to send common cardiac pattern data.

[Effect]

The recording control unit 5 uses the CPU to decode the electrocardiogram analysis result data of the subject by the electrocardiograph 1 supplied from the electrocardiogram analysis unit 2, and determines which finding name to record in text or which cardiac pattern and which one. It is determined in what positional relationship the marks should be superimposed, and the memory 4 is read out to instruct the combination of the corresponding cardiac pattern and mark together with the finding name in a predetermined format on the recording paper.

[Example of idea]

Next, an embodiment in which the present invention is applied to a telephone line transmission type electrocardiogram analysis device will be described with reference to FIG. On the center side, there are a telephone 11, an electrocardiogram analysis section 12, and a communication device 13 that sends the analysis result data to the telephone 11. On the terminal side, there are a telephone 14, a communication device 15, a data processing section 16 functioning as an interface, an electrocardiograph 17, and an ID data input device 1 for key-inputting identification data of the subject.
8, a ROM 20, a recording section 30 that prints one line at a time using a thermal head 31, and a recording control section 40. The ID data input device 18 allows the patient's identification number, gender, and age to be input by operating multiple keys, and the data processing unit 16 sends these data together with the electrocardiogram signal in a predetermined order through the communication device 15. The information is then transmitted through the telephone 14 over the telephone line. When the electrocardiogram signal is analyzed and an abnormality is diagnosed, the electrocardiogram analysis unit 12 selects one or more finding names and corresponding cardiac patterns and marks from a table of a predetermined number N, for example, several hundred types of findings. Specify the combination with The data processing unit 16
In addition to the above-mentioned functions, it is equipped with a buffer memory 16a corresponding to several pages of recording paper to temporarily store transmitted analysis result data, and the electrocardiogram analysis section 12 stores ID data, finding names, and their results. To transmit code data related to records of causes, treatments, and prognoses and store them at addresses corresponding to recording positions (rows and columns), and also to determine the types of heart patterns and marks and to combine them by superimposing them in a predetermined positional relationship. Also stores data regarding the matrix of recording start positions.

The ROM 20 stores an area 21 that stores character pattern data in units of 16 x 16 dots for records and marks indicating the site of findings, as well as a heart pattern in a longitudinal section along the front of the human body (see Figure 3).
First area 22 stored as 200 x 200 dot data, cross-sectional heart pattern (Figure 4)
A similar second area 23 storing , and a heart pattern in a longitudinal section along the side of the human body (Figure 5)
It includes a third area 24 storing .
The recording section 30 includes a thermal head 31 and records dot patterns line by line on the recording paper surface.

The recording control unit 40 has one line of character, mark, and heart pattern data read out from the ROM 20 loaded through an OR circuit 42, and a register 41 having a number of stages corresponding to the number of columns. Character data for each line is taken in from the buffer memory 43, which temporarily stores one line of dot data out of one line of dot data, and the buffer memory 16a, and the heart pattern, mark type, and start position data are stored in advance. Import and ROM20 based on the imported data
A control circuit 44 using a CPU that reads out the read data, loads the read data into the relevant stage of the register 41, and sequentially transfers one line of dot data in the loaded one line of data to the buffer memory 43. It is composed of. That is, the control circuit 4
4 performs reading by sequentially addressing each row of the buffer memory 16a in the column direction using the address counter, and reads the data from the ROM 2 at the address obtained by decoding this code data.
Read character pattern data of 0 and register 41
Set the column to which it belongs and load the character pattern data. When the counted value of the number of recording lines matches the recording start line of the cardiac pattern that has been captured in advance, the cardiac pattern area 22 designated by the electrocardiogram analysis unit 12
.about.24 is started, and after being added to the character data already loaded into the relevant stage of the register 41 using the OR circuit 42, the data is loaded into the relevant stage of the register 41 again. Such operations are repeated until all stages are completed. The heart pattern data is read out by the above operations for each line, and when the mark position is reached, the ☆ mark data is read out from the character data area 21, and the character data and heart pattern data loaded as described above are read out through the OR circuit 42. and is loaded into the relevant stage of register 41.

The operation is as follows.

Assume that the electrocardiogram analysis unit 12 diagnoses supraventricular extrasystole as a result of analyzing the electrocardiogram signal transmitted from the terminal side. The electrocardiogram analysis unit 12 stores the ID,
The characters of judgment, finding, cause, treatment, and prognosis as well as the code data of the recorded text of the contents are sent in sequence, and finally the heart pattern data regarding the memory area of the ROM 20 and its recording start position, and the characters ☆ and the position as marks are sent out. Send data. If there are a plurality of findings and two or three cardiac patterns are to be recorded, similar storage is performed in another page of the buffer memory 16a using a page break signal.

When the storage into the buffer memory 16a is completed, the recording control unit 40 sequentially takes in the character code data line by line, and also takes in the heart pattern data and mark data in advance. In Fig. 3, the ROM2
The dot pattern data of the character is read out and loaded into the corresponding stage of the register 41, and then transferred one dot line at a time to the buffer memory 43, and the dots are recorded on the thermal head 31.
Recording is performed horizontally on the recording paper line by line in the right direction, and when the heart pattern start line is reached, reading of that memory area is started, and the heart pattern data is stored in the corresponding column of the register 41 after loading the character pattern data. is also loaded and added. When the mark recording line is reached in this process, the dot pattern data of the ☆ mark is read out from the character data area 21.
It is added to the relevant stage of the register 41 and recorded by the thermal head 31.

In the above-described embodiment, the ID data input device 18 can function as an external operation means for instructing whether or not to record a heart pattern and mark in addition to the recorded text. That is, when these records are required, a predetermined key operation is performed and the electrocardiogram analysis section 1
2 to decode this key code data. If this data is not transmitted, the heart pattern data and mark data are not transmitted. Such an external operation means may be prepared separately from the ID data input device 18, or it may be provided at the center side and set according to a prior meeting. In order to distinguish between infarction, ischemia, etc., a plurality of marks may be recorded using words or ordinary letters. Furthermore, without transmitting the heart pattern and mark data from the electrocardiogram analysis unit 12, the control circuit 44, which is a CPU, can be provided with a function of determining the recording position of the heart pattern and marks based on the finding data. The present invention can also be applied to a non-transmission electrocardiogram analyzer, in which case the part 1 required for transmission is
1, 13-16 become unnecessary. The recording unit 30 is
A Y plotter or a dot printer may be used, and in this case, the recording control section 40 will have a suitable configuration.

[Effects of the invention] As described above, according to the present invention, findings diagnosed as a result of analyzing electrocardiogram signals are indicated not only by the name but also by the location of the finding on a picture of the heart, which makes it easy for non-specialists to understand. It also allows you to understand symptoms concretely and without any doubt. It is also convenient for specialists to provide explanations to patients. Furthermore, by storing in memory a few types of heart patterns that are common to many findings, storing marks indicating the location of findings in memory independently, and combining these data for each finding, it is possible to easily Such a device can be realized with a circuit configuration that saves memory capacity, especially a circuit configuration that saves memory capacity.
