摘要：The present invention provides systems and methods for performingautomated auscultation and diagnosis of conditions of the cardiovascular system. Theinvention acquires an acoustic signal emanating from the cardiovascular system via an

sensor. In addition, in certain embodiments of the invention an electrical signal, e.g., anelectrocardiogram (EKG) is simultaneously acquired. The signals are digitized, and,optionally, filtered to remove noise. The invention then processes and analyses thesignal(s) so as to provide a clinically relevant conclusion or recommendation such as adiagnosis or suggested additional tests or therapy. In preferred embodiments thesystem comprises: (1) a beat selection component that selects a plurality of beats foranalysis, wherein each beat comprises an acoustic signal emanating from the

cardiovascular system; (2) a time-frequency analysis component that performs a time-frequency decomposition of beats selected for analysis so as to identify or extractphysiologically relevant features; and (3) a processing component that processes theinformation so at to provide a clinically relevant conclusion or recommendation. Inpreferred embodiments of the invention the system further includes an aggregationcomponent that combines information obtained from a plurality of the beats selectedfor analysis. In one embodiment, the system diagnoses mitral valve prolapse.
