Abstract
Techniques are provided for use with an implantable cardiac stimulation device equipped with a multi-pole left ventricular (LV) lead having a proximal electrode implanted near an atrioventricular (AV) groove of the heart of the patient. A left atrial (LA) cardioelectrical event is sensed using the proximal electrode of the LV lead and a corresponding LA cardiomechanical event is also detected, either using an implantable sensor or an external detection system. The electromechanical activation delay between the LA cardioelectrical event and the corresponding LA cardiomechanical event is determined and then pacing delays are set based on the electromechanical activation delay for use in controlling pacing. The pacing delays can include, e.g., AV delays for use with biventricular cardiac resynchronization therapy (CRT) pacing. Other techniques described herein are directed to exploiting right atrial (RA) cardioelectrical events detected via an RA lead for the purposes of setting pacing delays.
