Abstract
For use by an implantable system including a first and second leadless pacemakers (LPs) implanted, respectively, in first and second cardiac chambers, a method comprises storing, within memory of the first LP, a paced activation morphology template corresponding to far-field signal components expected to be present in an EGM sensed by the first LP when a pacing pulse delivered to the second cardiac chamber by the second LP captures the second cardiac chamber. The method also includes the first LP comparing a morphology of a portion of an EGM sensed by the first LP to the paced activation morphology template to determine whether a match therebetween is detected, and determining whether capture of the second cardiac chamber occurred or failed to occur, based on whether the first LP detects a match between the morphology of the portion of the EGM and the paced activation morphology template.
