Abstract
There is provided a system and method applicable for use with a dual chamber pacemaker for determining whether long atrial intervals are due to atrial undersensing or to sick sinus syndrome. The determination of undersensing is based upon an algorithm which statistically analyzes a long atrial interval in terms of the patient's prior atrial rate history, and compares a calculated statistical probability measure with an empirically determined undersense threshold factor. The pacemaker can respond to a determination of undersensing by correcting already collected diagnostic data, adjusting one or more pacemaker operating parameters, adjusting synchronous tracking and/or providing an annotated marker channel for indicating undersense events.
