Study Summary
The purpose of this study is to analyze the effect of left ventricular lead pacing location in the non-left bundle branch block (non-LBBB) heart failure patient population. The left ventricular lead pacing location will be guided by either the pacing site with the largest amount of dyssynchrony as measured by the LV electrical delay (QLV) or the physician's standard of care implant approach.
Primary Outcome
Evaluate the Clinical Composite Score (CCS) at 12 months in NLBBB patients using a standard of care vs. latest electrical delay (QLV) implant strategy. The CCS has 4 components: New York Heart Association (NYHA) functional classification, Patient Global Assessment (PGA), heart failure (HF) events, cardiovascular death. NYHA Class ranges from Class I (least severe) to Class IV (most severe); possible PGA responses are "markedly worse", "moderately worse", "slightly worse", "no change", "slightly
