Figure 4

Subgroup analysis of primary composite outcome of time to death or heart failure hospitalizations among patients with left ventricular ejection fraction (LVEF) <50%. Conduction system pacing (CSP) vs conventional pacing (CP) and CSP vs biventricular pacing (BVP). Cox regression survival curves and multivariate analysis demonstrate significant reduction in the primary composite outcome (all-cause mortality or heart failure hospitalization) among patients with LVEF <50% when CSP was compared with CP or BVP.
