Values are % () for categorical and mean ± standard deviation or median (25th–75th percentile) for continuous variables. EP: electrophysiology; RV: right ventricle; RVOT: RV outflow tract; LV: left ventricle; CRT-P: cardiac resynchronization therapy pacemaker system; CRT-D: cardiac resynchronization therapy cardioverter-defibrillator system.
