Abstract:
1. A method of cardiac pacing employing a right ventricular electrode and a plurality of left ventricular electrodes, comprising: a) pacing using the right ventricular electrode and a first one of the left ventricular electrodes and measuring activation times at other ones of the left ventricular electrodes; b) pacing using the right ventricular electrode and a second one of the ventricular electrodes and measuring activation times at other ones of the left ventricular electrodes; and c) employing sums of the measured activation times to select one of the left ventricular electrodes for delivery of subsequent pacing pulses, d) wherein selection of the one of the left ventricular electrodes for delivery of subsequent pacing pulses is determined through a weighted electrical dyssynchrony equation (“(ED (j, A, D)”) defined as: wherein factor w(i, j) is a distance of a sensing electrode i from a pacing electrode j, n is a total number of left ventricular electrodes, A is atrio-ventricular delay, and D is time delay between pacing pulses in a right ventricle and a left ventricle.
