ABSTRACT:
A heart pacemaker normally operates at a basic pacing rate having a basic escape interval between pacing pulses associated therewith, so that the pulses are delivered at the basic rate in the absence of a sensed, pacer inhibiting heart event. The pacemaker includes circuitry for setting a hysteresis interval, added to the basic escape interval, to form an extended escape interval in response to the sensed, pacer inhibiting heart event, with the hysteresis interval being a function of the basic escape interval length.
