Abstract
Conduction volumitry 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.
Claims2
A method 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.
1 more element
A device for carrying out conduction volumetry on the heart comprising:
- a catheter having a blood exclusion volume;
- an array of electrodes on said blood exclusion volume;
- means for measuring the resitance between pairs of electrodes;
- means for computing the partial chamber volume associated with at least some of said electrodes over time generating a volume/time data set;
- means for computing the similarity between differing members of the volume/time data set to create a performance index.
