ABSTRACT:
An apparatus is disclosed for examining and analyzing cardiac pulses which is capable of determining instantaneous cardiac pulse frequencies, short and long-time averages of the instantaneous frequencies, drifts in the short and long-time averages, average fluctuations of the instantaneous pulse frequencies about the short-time average value, and the average rate of change of the fluctuations. The instantaneous cardiac pulse frequency may be determined from as few as two successive cardiac pulses.
