Abstract:
1. A method of operating a cardiac device to classify a cardiac response to a pacing pulse, comprising: delivering the pacing pulse to a heart; sensing a cardiac signal following delivery of the pacing pulse; determining if a peak of the cardiac signal falls within one of a plurality of detection windows associated with a non-captured, intrinsic response, each of the intrinsic detection windows finitely bounded in time and amplitude; classifying the cardiac response to the pacing pulse as the non-captured intrinsic response if the cardiac signal peak falls within one of the intrinsic detection windows; determining if the peak of the cardiac signal falls within a capture detection window finitely bounded by time and amplitude and associated with a captured response; classifying the cardiac response to the pacing pulse as the captured response if the peak of the cardiac signal falls within the capture detection window and not within an intrinsic detection window; and delivering pacing therapy based on the cardiac response classification.
