A method and apparatus delivering therapy 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 a second cardiac signal via a second electrode configuration, comparing, in response to an episode being present, portions of the second cardiac signal corresponding to the detected cardiac events with a predetermined template, and determining whether to deliver therapy in response to the comparing. |
