Claim:
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 measuring activation times at a plurality of the left ventricular electrodes; b) 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; c) computing a first degree of resynchronization based on a sum of differences of activation times in step a) and corresponding activation times in step b); d) 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; e) computing a second degree of resynchronization based on the sum of differences of activation times in step a) and corresponding activation times in step d); and f) selecting one of the left ventricular electrodes for delivery of subsequent pacing pulses based on the computed degrees of resynchronization in steps c and e.
