1. A method of operating a cardiac rhythm management device for classifying a cardiac response to a pacing pulse, comprising:

  • timing a plurality of cardiac pacing response classification intervals following delivery of the pacing pulse;

    sensing a cardiac signal in at least two classification intervals of the plurality of classification intervals;

    detecting at least one cardiac signal feature that occurs within a boundary region, the boundary region at least partially overlapping the at least two classification intervals;

    classifying the cardiac response to the pacing pulse based on the detected cardiac signal feature; and

    delivering pacing therapy based at least in part on classification of the cardiac response to the pacing pulse.
