Pacing interval adjustment for cardiac pacing response determination
First Claim
1. A method of determining a cardiac pacing response, comprising:
- adjusting one or more pacing intervals to achieve at least one cardiac pacing response waveform morphology that enhances determination of the cardiac pacing response;
pacing a heart using the one or more adjusted pacing intervals; and
determining the cardiac response to the pacing.

Abstract
The waveform morphology of a propagated pacing response signal may be adjusted to achieve a waveform morphology that enhances cardiac pacing response determination. One or more pacing intervals may be adjusted to achieve at least one cardiac pacing response waveform morphology that enhances determination of the cardiac pacing response. The heart is paced using the one or more adjusted pacing intervals and the cardiac response to the pacing is determined. The one or more adjusted pacing intervals may include an atrioventricular pacing delay, an interatrial pacing delay, an interventricular pacing delay, or other inter-chamber or inter-site pacing delays. Adjusting the one or more pacing intervals may be used to increase a difference between a first waveform morphology associated with multi-chamber capture and a second waveform morphology associated with single chamber capture.
