Abstract
A medical device is configured to deliver a high-energy electrical stimulation pulse to a patient that produces a post-stimulation polarization signal. A cardiac signal analyzer of the medical device is configured to detect a cardiac electrical signal superimposed on the post-stimulation polarization signal, determine at least one feature of the detected cardiac electrical signal, compare the feature to criteria that differentiate an intrinsic cardiac event during the post-stimulation polarization signal from an evoked response signal and identify the detected cardiac electrical signal as the intrinsic cardiac event if the feature meets the criteria.
