Study Summary
The objective of this study is to demonstrate that frequent atrio-ventricular (AV/PV) and inter-ventricular (V-V) delay optimization using QuickOpt in patients with cardiac resynchronization therapy device results in improved clinical response over standard of care (i.e. empiric programming or one-time optimization using any non-intracardiac electrogram optimization methods).
Primary Outcome
The clinical composite score classifies each randomized patient as improved, unchanged, or worse depending on the clinical response during and the clinical status at the end of the trial. Patients are considered improved if at the final visit they experienced a favorable change in NYHA functional class or in the patient global assessment (or both) but did not experience any major adverse clinical events during the course of the trial. Patients are considered worse if they experienced a major cli
