SYSTEM AND METHOD FOR CONFIGURING AN IMPLANTABLE MEDICAL DEVICE

摘要

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.

1. A method of providing CRT therapy to a patient with an implanted multi-site pacing medical device, wherein the method comprises:
determining an electrical delay associated with each of two or more left ventricle electrodes; comparing the electrical delay associated with each of the two or more left ventricle electrodes to an electrical delay threshold; if the electrical delay associated with one or fewer left ventricle electrodes is greater than the electrical delay threshold, selecting a left ventricle electrode for use during subsequent CRT therapy; and if the electrical delay associated with more than one left ventricle electrode is greater than the electrical delay threshold, selecting two or more of the left ventricle electrodes for use during subsequent CRT therapy.
