Abstract: An intracardiac ventricular pacemaker having a motion sensor is configured to produce a motion signal including an atrial systolic event and at least one ventricular diastolic event. The pacemaker is configured to set an atrial refractory period, detect a change in a ventricular diastolic event metric and adjust the atrial refractory period in response to detecting the change. The pacemaker sets set an atrioventricular pacing interval in response to detecting the atrial systolic event from the motion signal after expiration of the atrial refractory period.

Abstract: A medical device system including at least a first implantable medical device and a second implantable medical device is configured to establish by a control module of the first implantable medical device whether the second implantable medical device is present in a patient and self-configure an operating mode of the control module in response to establishing that the second implantable medical device is present.
