ABSTRACT:
Method and apparatus for detecting coronary stenosis. The apparatus comprises an acoustic sensor and a microcomputer that identifies the standard S1 and S2 heart sounds, heart rate, and determines the diastolic interval of the subject and thereafter estimates the acoustic energy levels within a 2 octave band around approximately 20 Hz during diastole. Based upon such estimation, a diagnosis can be rendered as to the presence and degree of stenosis from the coronary artery.
