Abstract
Conduction volumetry is used to determine the hemo-dynamic performance of the heart under various pacing protocols to optimize cardiac output as a function of the pacing protocol.
Claims (5)
1. A method, performed once at the time of implantation of one or more pacing leads, of optimizing a pacing site for a heart chamber of a congestive heart failure patient comprising:
pacing the heart a plurality of sites;
measuring a number of partial chamber volumes of the heart chamber over time through out one heartbeat generating a volume/time data set;
constructing a measure that compares the self-similarity of volume/time data set;
selecting the pacing conditions corresponding to the most self-similar volume time data.
