Abstract
This invention concerns a method and system for automatically determining heart rate. The invention can be applied to determining the heart of any animal including humans. The method involves sensing body sounds and transducing them to electrical signals. Digitizing the electrical signals. Emphasizing the heart sound maxima (Sand Ssignals) relative to noise by filtering, decompression and squaring. Detecting local maxima in the signals as likely Ssignals and generating a threshold amplitude. Selecting maxima that exceed the threshold as surviving likely candidate Ssignals. Screening the surviving candidate Sagainst physiologically derived criteria. And, calculating the heart rate from the screened S.
