Claim 9:
10. The method of claim 8, further comprising:
determining a first onset interval corresponding to a length of time between a beginning of the specified window and when the portion of the His IEGM exceeds the specified sense threshold within the specified window;
further pacing the patient's right atrium to thereby cause a further paced atrial event;
determining whether a further portion of the His IEGM exceeds the specified sense threshold within a further specified window that begins at an end of an extended AVD following the further paced atrial event, wherein the extended AVD is equal to the AVD plus an extension interval that is less than the first onset interval;
determining a second onset interval corresponding to a length of time between a beginning of the further specified window and when the further portion of the His IEGM within the further specified window exceeds the specified sense threshold;
determining whether the second onset interval is equal to the first onset interval minus the extension interval; and
detecting the atrial oversensing in response to determining that the second onset interval is equal to the first onset interval minus the extension interval.
