Techniques are provided for use with an implantable cardiac stimulation device equipped for multi-site left ventricular (MSLV) pacing using a multi-pole LV lead. In one example, MSLV interelectrode conduction delays are determined among the electrodes of the multi-pole LV lead. MSLV interelectrode pacing delays are then set based on the MSLV interelectrode conduction delays for use in delivering MSLV pacing. To this end, various criteria are exploited for determining optimal values for the pacing delays based on the interelectrode conduction delays. MSLV pacing is then controlled using the specified MSLV interelectrode pacing delays. In some examples, the optimization procedure is performed by the implantable device itself. In other examples, the procedure is performed by an external programmer device. In such an embodiment, the external device determines optimal MSLV interelectrode pacing delays and then transmits programming commands to the implantable device to program the device to use the pacing delays.
