Claim 0:
1. A method for use with an implantable system including at least an atrial leadless pacemaker (aLP) configured to be implanted in or on an atrial chamber of a patient's heart and configured to selectively deliver a pacing pulse to the atrial chamber, the method comprising:
the aLP sensing a signal from which cardiac activity associated with a ventricular chamber of the patient's heart can be detected by the aLP itself based on one or more features of the sensed signal;
the aLP specifying a ventricular event monitor window;
the aLP monitoring the sensed signal for a ventricular activation within the ventricular event monitor window; and
in response to the aLP detecting said ventricular activation itself from the sensed signal within the ventricular event monitor window, the aLP resetting an atrial escape interval timer that is used by the aLP to time delivery of an atrial pacing pulse if an intrinsic atrial activation is not detected by the aLP within an atrial escape interval.
