1. A method of classifying a cardiac response to a pacing pulse, comprising:
- sensing a cardiac response to a pacing pulse via multiple sense channels, each sense channel comprising a distinct combination of sense electrodes and sensing circuitry;
classifying the cardiac response to the pacing pulse based on morphology of cardiac response signals sensed via the multiple sense channels, wherein classifying the cardiac response comprises discriminating between capture, fusion, non-capture, and non-capture with intrinsic activity.

Abstract
Methods and systems involve classifying the cardiac response to pacing using a multi-channel approach. Multiple cardiac response signals are sensed via multiple sense channels. Each sense channel comprises a distinct combination of electrodes and sensing circuitry. The cardiac response to the pacing pulse is classified based on the morphology of the cardiac response signals. Classifying the cardiac response involves discriminating between capture, fusion, non-capture, and non-capture with intrinsic activity.
