Claim 22:
23. A method for use by a medical device or system implanted within a patient, the method comprising:
sensing an intracardiac electrogram (IEGM) using at least one electrode implanted in an atrium of the patient;
based on the IEGM, measuring intervals between a plurality of intrinsic atrial depolarizations that occur during a specified period and determining that the patient is experiencing an atrial tachycardia or atrial fibrillation (AF) while an intrinsic atrial rate of the patient is within a specified range;
calculating a mean and a standard deviation of at least a subset of the plurality of intrinsic atrial intervals; and
determining, based on the mean and the standard deviation, whether to perform atrial overdrive pacing while the patient is experiencing the atrial tachycardia or AF and the intrinsic atrial rate of the patient is within the specified range.
