METHOD OF FACILITATING SELECTION OF A VECTOR FOR DELIVERING ELECTRICAL STIMULATION TO A PATIENT

摘要

Method of facilitating selection of a vector for delivering electrical stimulation to a patient's heart via an electro-stimulation device having three or more electro-stimulation electrodes, the method comprising displaying a plurality of vectors on a display screen, wherein each vector represents a different combination of the three or more electro-stimulation electrodes. In one example, an intrinsic electrical delay associated with each of two or more left ventricle electrodes may be determined (400). The intrinsic electrical delay associated with each of the two or more left ventricle electrodes may be compared (402) to an electrical delay threshold. A single left ventricle electrode may be selected (404) or two or more of the left ventricle electrodes may be selected (406) for use during subsequent CRT based on the comparison.
