Non-Invasive Acoustic Screening Device For Coronary Stenosis
US Patent:
6048319, Apr 11, 2000
Filed:
Oct 1, 1998
Appl. No.:
9/164618
Inventors:
Lonnie H. Hudgins - Aliso Viejo CA
Premindra A. Chandraratna - Rancho Palos Verdes CA
Premindra A. Chandraratna - Rancho Palos Verdes CA
Assignee:
Integrated Medical Systems, Inc. - Signal Hill CA
International Classification:
A61B 700
US Classification:
600528
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.
