Abstract

An atrial leadless pacemaker (aLP) (102a), of a dual chamber leadless pacemaker system (100) that also includes a ventricular leadless pacemaker (vLP) (102b), senses intrinsic atrial events and for each intrinsic atrial event that is sensed determines a respective atrial-to-atrial interval (AA interval) that corresponds to a duration between the intrinsic atrial event and an immediately preceding intrinsic atrial event. Additionally, the aLP (102a), based on the determined AA intervals, selectively transmits and selectively abstains from transmitting atrial event messages to the vLP (102b). When the aLP (102a) abstains from transmitting atrial event messages to the vLP (102b), the aLP (102a) conserves power thereby increasing its longevity. The aLP (102a) can also be configured to operate in a similar manner for paced atrial events, to further conserve power. The vLP (102b) utilizes its W interval timer to determine when to deliver ventricular stimulation, during those times that the aLP (102a) abstains from transmitting atrial event messages to the vLP (102b).
