Figure 2 Major cardiac events (cardiac death or heart transplantation) according to ventricular dyssynchrony. (Upper) Cardiac events according to interventricular (IV) delay. (Middle) Cardiac events according to left intraventricular dyssynchrony. (Lower) cardiac events according to right intraventricular dyssynchrony. CI = confidence interval; CV = cardiovascular; FU = follow-up; LV = left ventricle; RV = right ventricle; SD = standard deviation.
