A method and apparatus for determining oversensing in an implantable medical device that includes sensing a first cardiac signal and detecting cardiac events via a first electrode configuration, determining the presence of an episode requiring therapy in response to the detected cardiac events, sensing the first cardiac signal via a second electrode configuration, determining a baseline measurement of samples of the first cardiac signal sensed via the second electrode configuration, and determining whether to deliver therapy in response to the baseline measurement.
