Abstract
Heartbeat data is measured and converted into a series of electrical output pulses, the frequency of which is related to the heartbeat pulse rate. The output pulses trigger 'on' and 'off' a timing device, and the average time of a heartbeat cycle is then converted into a heartbeat pulse rate and displayed. The timing device includes a means for delaying a first specified number of output pulses before beginning the sampling period and registering a count of clock pulses which represents the time period of a second specified number of the output pulses occurring subsequently to the first specified number of output pulses.
