ABSTRACT:
An implantable cardiac pacemaker and a method of its operation. The pacemaker delivers pacing pulses to a first chamber of a patient's heart and senses depolarizations of a second chamber of the patient's heart. The amplifier for sensing depolarizations of the second chamber of the patient's heart defines a base sensing threshold and, responsive to delivery of a pacing pulse to the first chamber of the patient's heart for defines an increased sensing threshold greater than the base sensing threshold. The increased sensing threshold persists for a defined period of time following delivery of a pacing pulse to the first chamber of the patient's heart and thereafter gradually decreases from the increased sensing threshold to the base sensing threshold.
