Abstract
Apparatus for discriminating between heartbeat and artifact information contained in an ECG signal includes a pair of difference amplifiers, level-detecting circuitry and a coincidence detector. ECG waveforms are obtained from a number of heartbeat-sensing transducers attached to a person. The waveforms are individually applied to a pair of difference amplifiers to produce difference signals containing heartbeat information. The difference signals are applied to level-detecting circuits and compared to predetermined voltage levels to identify particular peaks indicative of a heartbeat. The result of the level-detecting circuits are compared for time coincidence to produce an output pulse indicative of a heartbeat.
