First Claim
Patent Images
1. A method of determining a cardiac response to a pacing pulse, comprising:
- providing a plurality of electrodes electrically coupled to a heart;
delivering the pacing pulse to the heart using a first electrode combination;
sensing a single cardiac signal for cardiac response classification following the pacing pulse using a second electrode combination; and
classifying the cardiac response to the pacing pulse as one of a captured response, a non-captured response, and a fusion/pseudofusion response by distinguishing between each of the captured, non-captured, and fusion/pseudofusion responses using the single cardiac signal without using any other cardiac signal sensed following the pacing pulse.

Abstract
Methods and devices for classifying a cardiac pacing response involve using a first electrode combination for pacing and a second electrode combination for sensing a cardiac signal following pacing. The cardiac response to pacing may be classified using the sensed cardiac signal. One process involves using the sensed cardiac signal to detect the cardiac response as a fusion/pseudofusion beat. Another process involves using the sensed cardiac signal to classify the cardiac response to pacing as one of at least three cardiac response types.
