ABSTRACT:
A fixed interval, variable period technique for measuring pulse rate including defining the start and the end of a fixed measuring interval, counting the pulses whose rate is to be measured beginning in response to the start of the measuring interval and stopping in response to the end of the measuring interval; measuring the period of time between the occurrence of the first counted pulse and the last counted pulse; and dividing the number of pulses counted during a measuring period by the period to determine the pulse rate.
