1. A method for use by a leadless pacemaker (LP) configured to perform conductive communication with another implantable medical device (IMD), while the LP and the other IMD are implanted in a patient, the method comprising the LP:
storing information that specifies when, within a cardiac cycle of the patient, the LP and the other IMD implanted in the patient are likely oriented relative to one another such that conductive communication between the LP and the other IMD should be successful;
sensing a signal indicative of cardiac activity of the patient over a plurality of cardiac cycles; and
outputting one or more conductive communication pulses, during a portion of at least one of the cardiac cycles, wherein the portion of the at least one of the cardiac cycles is identified based on the signal that is sensed and the information that is stored.
