System and method for assessing and selecting stimulation vectors in an implantable cardiac resynchronization therapy device
First Claim
1. A method of selecting stimulation vectors for a multi-site pacing medical device, the method comprising:
- determining a pacing parameter associated with each of two or more left ventricle (LV) electrodes;
andselecting a number of LV electrodes for use during subsequent CRT therapy, wherein the selecting includes determining whether the subsequent CRT therapy is single-site LV pacing stimulation or multi-site LV pacing stimulation using the determined pacing parameters and spacing information of the two or more LV electrodes.

Abstract
Systems and methods for providing CRT therapy to a patient with an implanted multi-site pacing medical device. In one example, an intrinsic electrical delay associated with each of two or more left ventricle electrodes may be determined. The intrinsic electrical delay associated with each of the two or more left ventricle electrodes may be compared to an electrical delay threshold. If the electrical delay associated with one or fewer left ventricle electrodes is greater than the electrical delay threshold, a single left ventricle electrode may be selected for use during subsequent CRT therapy. If the electrical delay associated with more than one left ventricle electrode is greater than the electrical delay threshold, two or more of the left ventricle electrodes may be selected for use during subsequent CRT therapy.
