Heart disease diagnostic device, heart disease diagnostic program and medium

摘要

PROBLEM TO BE SOLVED: To provide a cardiac disease diagnostic apparatus for determining the presence or absence of a cardiac disease on the basis of cardiac sound data in a systole.SOLUTION: A cardiac disease diagnostic apparatus 1 comprises: a cardiac sound detection unit 11 for detecting electric signals based on cardiac sound of a living body; an input signal processing unit 12 for applying prescribed signal processing to the electric signals and outputting cardiac sound data; a cardiac sound analysis unit 13 for extracting at least either sound signal among a I sound signal and a II sound signal from the cardiac sound data, and diagnosing a cardiac disease of the living body by comparing at least either amplitude or power of a first frequency band between a first frequency and a second frequency higher than the first frequency in the sound signal with a first reference value.SELECTED DRAWING: Figure 3
