Abstract
An electronic heart sound detector in which a transducer detects the two primary heart beats of the heart cycle to produce a signal which is converted to a digital signal, filtered and the intervals between adjacent transitions determined and stored. The intervals are compared with previous values, successive values added if found substantially different and the stored or added values displayed if substantially the same as a previous correct value. The functions may be carried out by a microprocessor.
