Abstract

PROBLEM TO BE SOLVED: To complement a weak point of automatic analysis of a cardiogram by a computer. SOLUTION: An inner program for recording result of diagnosis in a recorder is provided by analyzing plural representative heartbeats in order, and separately recording results of these with waveforms to provide such a recording form that diagnosis about which result is adopted can be entrusted to a doctor. Even where artifacts, etc., are mixed in part of plural representative heartbeats, when they are not mixed in the other representative heartbeats, result of analysis for the representative heartbeats can be finally adopted. Even in the case where difference is generated for results of analysis for plural representative heartbeats by little difference in waveforms, result for that of the highest reliability under doctor's determination can be finally adopted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrocardiogram analyzer, and more particularly to an electrocardiogram analyzer which outputs the contents of diagnosis by analyzing an electrocardiogram and a heartbeat.

[0002]

2. Description of the Related Art An electrocardiogram analyzing apparatus according to the prior art selects a specific heartbeat from a continuous waveform of an electrocardiogram for a predetermined time (for example, within 5 seconds), sets the selected heartbeat as a representative heartbeat, and then selects a representative heartbeat.
Waveform measurement was performed using the representative heartbeat for the lead, and the findings of the electrocardiogram were analyzed based on the measurement results.

[0003]

A problem with the prior art is that, when an artifact or the like is mixed in one heartbeat as a representative heartbeat, an incorrect finding is analyzed. The reason is that the artefact or the like is mixed in the representative heartbeat, thereby failing to recognize the segmentation point of the electrocardiogram waveform, and as a result, the measured values of the time width and amplitude of each spike wave become erroneous values.

[0004] An object of the present invention is to provide an automatic analysis of an electrocardiogram, even if an artifact or the like is mixed, by making a selection based on diagnosis of a plurality of heartbeats. The purpose is to supplement the weakness of the automatic ECG analysis by the computer.

[0005]

Means for Solving the Problems A first invention of the present invention is:
An electrocardiogram analyzer, comprising: means for storing measured values of a plurality of heartbeats and a diagnosis name; and means for performing waveform measurement and waveform analysis on the plurality of heartbeats.

According to a second aspect of the present invention, there is provided an electrocardiogram analyzing apparatus according to the first aspect, further comprising means for displaying, on an LCD screen, a measured value of a waveform measurement result for a plurality of heartbeats and a diagnosis name of the waveform analysis together with the waveform. apparatus.

According to a third aspect of the present invention, there is provided an electrocardiogram analyzing apparatus according to the first aspect, further comprising means for recording, on a recording paper, all measured values of waveform measurement results for a plurality of heartbeats and a diagnosis name of the waveform analysis together with the waveform. apparatus.

[0008] A fourth invention of the present invention is characterized in that a means is provided for an operator to select a measurement value of a result of waveform measurement for a plurality of heartbeats and a diagnosis name of waveform analysis, and to make the result of the test a result. An electrocardiogram analyzer according to the second aspect.

According to a fifth aspect of the present invention, an operator selects a measurement value of a waveform measurement result and a diagnosis name of a waveform analysis result for a total of three heartbeats, that is, a representative heartbeat and one heartbeat before and after the representative heartbeat. The electrocardiogram analyzing apparatus according to the second invention, characterized by comprising means for:

According to a sixth aspect of the present invention, there is provided an electrocardiogram analyzing apparatus for performing automatic analysis of an electrocardiogram, sequentially analyzing a plurality of heartbeats, and recording a plurality of diagnostic results in a single analysis process.

[Action] A diagnosis result based on a plurality of heartbeats is
Since each is recorded on a recorder such as a recorder, a physician who examines it verifies the waveform against an analysis target waveform. If the waveform to be analyzed has any abnormality (artifacts, etc.), the analysis result is ignored, and the analysis result that is considered to be the most plausible among the remaining diagnosis results is used. The results are used as the final ECG findings of the ECG test.

To record on the recording paper.

Next, the operation of the electrocardiogram analyzer of this embodiment will be described with reference to the flowchart shown in FIG.

The waveform of the electrocardiogram signal digitized by the AD converter 3 is analyzed according to the following procedure. The representative heartbeat is determined in step S1. Then, step S
In step 2, for one heartbeat of the representative heartbeat, the section point recognition of each spike is performed. Then, in step S3, the time width and amplitude of each spike are measured. In step S4, a finding is determined based on the measurement value obtained in step S3.

Then, in step S5, the next representative heartbeat is selected, and in step S6, the same processing as in steps S2 to S4 is performed. Further, the next representative heartbeat is selected in step S7, and the same processing as steps S2 to S4 is performed in step S8. Then, in step S9, step S3,
The three types of finding names obtained in S6 and S7 are recorded in the recorder together with the waveform of each representative heartbeat.

[0017]

The first effect of the present invention is that even if an artifact or the like is mixed in a part of a plurality of representative heartbeats, if it is not mixed in the remaining representative heartbeats, the analysis result for the representative heartbeat is finalized. This has the effect of being able to be adopted on a regular basis.

The second effect of the present invention is to use one result which has the highest credibility in the judgment of the doctor even if there are differences in analysis results due to a plurality of representative heartbeats due to slight differences in waveform. The effect is that you can do it.
