Electrical optimization by RVLV Conduction Time with VectSelect
"VectSelect Quartet multivector testing is a programmer-based feature that provides centralized vector testing and programming with the flexibility to select the appropriate pacing vector to meet individual patient needs.~The Right ventricle - Left Ventricle (RV-LV) conduction time measurement will automatically identify the RV-LV conduction time for each LV electrode ."
Anatomical optimization of device and leads
Patients will be implanted with left ventricular leads which will be positioned most basal, most apical or midway in the left ventricle. This follows the physician's routine clinical practice and judgement.
Implanted device and lead (Cardiac Resynchronization Therapy Defibrillator (CRT-D) device and SJM Quadripolar lead system)
All participants will be implanted with a St Jude Medical (SJM) Cardiac Resynchronization Therapy Defibrillator (CRT-D) device and SJM Quadripolar lead system. Patients who fulfill the criteria for CRT D implant, will be invited to participate in this clinical investigation. Patients implanted with chronic leads requiring device upgrade to CRT-D can also be enrolled in the study, provided they are receiving a CRT-D device for the first time.
