Abstract
A method and apparatus for determining oversensing in a medical device that includes sensing cardiac signals and detecting cardiac events via a first electrode configuration, determining the presence of an episode event in response to the detected cardiac events, and sensing the cardiac signals via a second electrode configuration. Amplitudes associated with a predetermined number of cardiac signals sensed via the second electrode configuration corresponding to the event episode are determined, and delivery of therapy is controlled in response to the determined amplitudes.
