ABSTRACT:
Apparatus for monitoring the heartbeat of a person by screening the occurrence of a heartbeat from artifact to produce a signal indicative of the heartbeat occurrence. Screening circuitry detects the R-wave and S-wave peaks of an ECG signal, delays the R-wave peak detection and compares the delayed R-wave peak detection to the S-wave peak detection for coincidence to determine a heartbeat occurrence. Binary counting circuits compare the elapsed time between any two immediately successive heartbeat occurrence indications to determine heartbeat rate. Display apparatus, operably coupled to the counting circuits, provides indicia of the relative heartbeat rate.
