ABSTRACT:
A medical device system and associated method sample an EGM signal over a processing window having a predetermined time duration. A number of morphology metrics are determined from the sampled EGM signal, and a heart rhythm is detected in response to the morphology metrics without determining depolarization intervals. The morphology metrics include metrics determined from a slope signal derived from the EGM signal in one embodiment.
