Abstract

Dual chamber leadless pacemaker systems comprising an atrial leadless pacemaker (aLP) (102) and a ventricular leadless pacemaker (vLP) (104) are disclosed. Such systems can detect and terminate pacemaker mediated tachycardia (PMT) even when the implant-to-implant (i2i) communication from the vLP (104) to aLP (102) (V2A) is compromised. The vLP (104) monitors for PMT in response to reception of an i2i communication from the aLP (102) indicating compromised V2A i2i communication and initiates, following detection of a PMT, initiate a PMT PV interval in response to reception of an i2i communication from the aLP (102) indicating an atrial sensed event. The PMT PV interval is shorter than a PV interval that the vLP (104) would otherwise use for ventricular pacing if PMT was not detected. The vLP (104) also delivers a ventricular pacing pulse to the ventricular cardiac chamber in response to the PMT PV interval expiring without an intrinsic ventricular event being detected during the PMT PV interval.
