System and method for evaluating and optimizing the contribution of particular heart chambers to the overall efficacy of cardiac pacing therapy
First Claim
1. A method for use in delivering cardiac pacing therapy to the heart of a patient in which an implantable cardiac stimulation device is implanted, the method comprising the steps of:
- delivering cardiac pacing therapy to the heart of a patient using a pacing mode, the pacing mode specifying which chambers of the heart are paced;
temporarily altering the pacing mode with which pacing therapy is delivered;
detecting transient changes in the efficacy of pacing therapy following the alteration in pacing mode;
determining the contribution of particular heart chambers to the overall efficacy of pacing therapy based on the alteration in the pacing mode and on any transient changes in the efficacy of the pacing therapy; and
recording diagnostic information indicative of the contribution of particular heart chambers to the overall efficacy of pacing therapy.

Abstract
Techniques are provided for evaluating and optimizing the contribution of particular heart chambers to pacing efficacy. Briefly, a pacemaker temporarily alters the mode with which pacing therapy is delivered so as to selectively alter the heart chambers that are paced. The pacemaker detects any transient changes in pacing efficacy following the alteration in pacing mode. The pacemaker then assesses the contribution of particular heart chambers to pacing efficacy based on the alteration in the pacing mode and on any transient changes in the pacing efficacy. Additionally, techniques are provided herein for automatically adjusting pacing parameters to optimize the contribution of particular chambers to pacing efficacy.
