This study was designed to compare the rotation of the left ventricular (LV) apex and base, LV synchrony between LV apical and basal rotation, and LV twist, changing from intrinsic atrioventricular conduction to right ventricular apical (RVA) pacing. Thirty consecutive patients with sick sinus syndr...
