ABSTRACT:
A miniature tape recorder intended for ambulatory recording of cardiac signals over a twenty-four-hour interval includes a clock with a visual display and an event marking circuit. Cardiac signals are recorded simultaneously on two tracks on the magnetic tape used by the recorder. The event marking circuit, activated by the patient, interrupts briefly the recording of cardiac signals on one of the tracks to record in its place an event marker signal easily recognizable on playback. The event marking circuit includes a clock circuit, a counter, and logic circuits to generate a burst of exactly eight square pulses of predetermined width, the duration of the burst being one second.
