Abstract
A system includes, or is for use with, an atrial leadless pacemaker (aLP) and a ventricular leadless pacemaker (vLP) configured to communicate with one another and collectively provide DDD operation when an a2v message transmitted by the aLP is successfully received by the vLP and a v2a message transmitted by the vLP is successfully received by the aLP, during a cardiac cycle. The aLP and the vLP are also configured to collectively provide VDD operation, DDI operation or VDI operation at least some times when an a2v message transmitted by the aLP is not successfully received by the vLP, and/or a v2a message transmitted by the vLP is not successfully received by the aLP. One or more processors of the system is/are configured to determine an AV synchrony metric for the period of time, and provide one or more responses based thereon. Related methods are also described.
