Heart sound analyzer, heart sounds analytical methods and heart sounds analysis program

摘要

PROBLEM TO BE SOLVED: To provide a cardiac sound analysis device for automatically determining whether cardiac sound is normal or abnormal by analysing the cardiac sound.;SOLUTION: A peak section information generation part generates a binarized signal with a peak section corresponding to a section with cardiac sound and/or cardiac murmur and a 0-value section corresponding to other sections. An evaluation value calculation part calculates one or a plurality of evaluation values obtained by statistically processing a duration of each peak section. A determination part executes cardiac sound abnormality determination based on a variation tendency of evaluation values resulting from the difference between a case of normal cardiac sound and a case of abnormal cardiac sound.;COPYRIGHT: (C)2014,JPO&INPIT
