Figure 3 Functional and Mechanical Response to Various Modes of CRT in RBBB-HF
Effect of cardiac resynchronization therapy (CRT) in right bundle branch block (RBBB) + heart failure (HF) for all pacing combinations expressed as a percent change from right-atrial-paced baseline. *p < 0.007 compared with baseline; 
p < 0.047 compared with baseline; 
p < 0.005 compared with left ventricular (LV)-only pacing; 
p = 0.015 compared with LV-only pacing. BiV = biventricular; CURE = circumferential uniformity ratio estimate; dP/dtmax = maximum time derivative of left ventricular pressure; RV = right ventricular.
