Problems solved by technology

[0026] However, in the synthetic electrocardiogram generation system of JP-A-2012-029904, in order to calculate the individual coefficients for synthesizing the required leads, it is necessary to measure the leads of any part of the subject itself in advance, so there is a problem that the system is cumbersome and cumbersome

Embodiment Construction

[0040] In the embodiment, it is assumed that the individual coefficient of a specific subject to be subjected to electrocardiogram measurement is correlated with the population coefficient of a population including a predetermined number of individuals, and the specific subject is synthesized from measured leads obtained by measuring the electrocardiogram of the specific subject additional leads. The synthetic lead waveform is then added to the measured lead waveform to generate a synthetic electrocardiogram. The term "patient" is used as a specific example of a subject whose electrocardiogram measurement is to be performed. The subject means not only a patient examined at a hospital but also a facility other than a hospital such as a testing center or a clinic that performs a physical examination or a user at an ordinary home.

[0041] Of course, the electrocardiogram measurement device and synthetic electrocardiogram generation method and program of the embodiment can be ap...

Abstract

An electrocardiogram measuring apparatus includes: a population coefficient calculating unit which calculates: first population coefficients; and second population coefficients; a personal coefficient calculating unit which calculates: first personal coefficients; and second personal coefficients; and a lead deriving unit which: calculates first personal coefficients of a specific subject based on: a relationship between a magnitude of a ratio of the first population coefficients to the second population coefficients, and a magnitude of a ratio of the first personal coefficients to the second personal coefficients; and second personal coefficients of the specific subject which are calculated based on A leads of the specific subject, the A leads being acquired by electrocardiogram measurement; and synthesizes B leads of the specific subject by using the first personal coefficients of the specific subject.

Description

technical field [0001] The invention relates to an electrocardiogram measuring device and a synthetic electrocardiogram generating method. Background technique [0002] In the case of obtaining a standard 12-lead ECG from a patient, 10 electrodes connected to an electrocardiograph as an ECG measurement device are used, and they are respectively attached to 6 positions for measuring the chest leads and for Measure the 4 positions of the limb leads. Then, at the heart potential detected from the 10 electrodes, the electrocardiograph calculates and outputs the standard 12-lead 6 limb lead waveforms (I, II, III, aVR, aVL, and aVF) and the standard 12-lead 6 Chest lead waveforms (V1, V2, V3, V4, V5, and V6). [0003] Typically, the relationship between the lead waveforms used to obtain a standard 12-lead ECG and the cardiac potential in the measurement site is as follows: [0004] Lead I: vL-vR [0005] Lead II: vF-vR [0006] Lead III: vF-vL [0007] Lead aVR: vR-(vL+vF) / 2...
