Classification: CPC A | IPC A

Claim 11:
12. A method for use with an implantable medical system, the method comprising:
obtaining a His intracardiac electrogram (His IEGM) sensed using at least one electrode implanted in or proximate to a patient's His bundle;
sensing or pacing a right atrium of the patient to thereby sense or pace an atrial event;
determining whether a portion of the His IEGM exceeds a specified sense threshold within a specified window within an atrioventricular delay (AVD) following the sensed or paced atrial event; and
detecting an atrial signal component within the His IEGM based on results of the determining whether the portion of the His IEGM exceeds the specified sense threshold within the specified window within the AVD, wherein the detecting the atrial signal component within the His IEGM is indicative of potential atrial oversensing; and
triggering ventricular pacing in response to detecting the portion of the His IEGM exceeding the specified sense threshold within the AVD;
wherein the method is performed while the implantable medical system is in one of DDT or DDD mode.
