Abstract
An implantable system including an atrial leadless pacemaker (aLP) and a ventricular leadless pacemaker (vLP), and methods for use therewith, are configured or used to terminate a pacemaker mediated tachycardia (PMT). In an embodiment, in response to the aLP detecting a PMT, the aLP initiates a PMT PA interval, and the aLP does not inform the vLP, via an i2i communication, of an atrial sensed event that caused the PMT to be detected, thereby preventing the vLP from initiating a PV interval during the PMT PA interval. The aLP selectively terminates the PMT PA interval. Additionally, the aLP informs the vLP, via an i2i communication, of an intrinsic atrial event being detected during the PMT PA interval, or of an atrial paced event being performed in response to the PMT PA interval expiring without an intrinsic atrial event being detected during the PMT PA interval.
