Abstract: A signal processing circuit for use in a digital memory-type EKG display system wherein analog EKG signals are periodically sampled and converted to a digital signal for processing and display comprises an amplitude hold circuit which maintains the instantaneous amplitude of pacemaker pulses contained in the analog EKG signal constant for a sufficient period of time to insure recognition of the pulses in the next sampling. Because no access is required to the sampling or conversion circuits of the system, the processing circuit can be readily added to an existing system.
