Patent ID: 8583230

Claim:
A method for use with an implantable cardiac stimulation device equipped for multi-site left ventricular (MSLV) pacing using a multi-pole LV lead in combination with an RV lead, the method comprising: detecting intraventricular and interventricular conduction delays for paced cardiac events; determining maximum pacing time delays for use with MSLV pacing, wherein the maximum pacing time delays are set, based on the conduction delays, to values sufficient to avoid capture problems due to wavefront propagation; setting MSLV pacing time delays to values no greater than the maximum pacing delays; and controlling the delivery of ventricular pacing to deliver a set of pulses using the MSLV pacing delays; wherein the device accommodates two programmable MSLV delays (IED# 1 and IED# 2 ); wherein the device is programmed to apply a first MSLV pacing sequence (Seq#1) wherein an RV pulse is followed by an LV 1 pacing pulse and then by an LV 2 pacing pulse, wherein LV 1 represents a first LV pacing site, LV 2 represents a second LV pacing site, and a first pacing delay (IED# 1 ) is applied between the RV and LV 1 pulses and a second pacing delay (IED# 2 ) is applied between the LV 1 and LV 2 pulses.
