Claim 7:
8. A method for use with an implantable medical system configured to selectively perform His capture management, 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;
pacing the patient's right atrium using at least one electrode implanted in the patient's right atrium to thereby cause a paced atrial event;
determining whether a portion of the His IEGM exceeds a specified sense threshold within a specified window that begins at an end of an atrioventricular delay (AVD) following the paced atrial event;
detecting atrial oversensing based on results of the determining whether the portion of the His IEGM exceeds the specified sense threshold within the specified window;
preventing performance of the His capture management in response to detecting the atrial oversensing; and
after detecting the atrial oversensing, at a later point in time that the atrial oversensing is no longer detected, performing the His capture management, which includes pacing of the patient's His bundle, using the at least one electrode implanted in or proximate to the patient's His bundle, and determining a capture threshold associated with the patient's His bundle.
