Abstract
Methods and systems for terminating a pacemaker mediated tachycardia (PMT) are described herein. During a period that a PMT is not detected, an implantable system delivers an atrial pacing pulse to an atrial cardiac chamber in response to a PA interval expiring without an intrinsic atrial event being detected during the PA interval. The systems performs atrial sensing to thereby monitor for intrinsic atrial events in the atrial cardiac chamber, performs ventricular sensing to thereby monitor for intrinsic ventricular events in a ventricular cardiac chamber, and detects the PMT. Additionally, the system, in response to the PMT being detected, initiates a PMT PA interval that is shorter than the PA interval that the system would otherwise use for atrial pacing if the PMT was not detected.
