Right ventricular lead adjustment in cardiac resynchronization therapy and acute hemodynamic response: a pilot study.

Purpose: Optimal left ventricular (LV) lead position has emerged as an important determinant of response after cardiac resynchronization therapy (CRT). Comparatively, strategy for right ventricular (RV) lead optimization remains uncertain.

Methods: Three variations of RV lead position (apex, mid-septal, and high septal) were tested in seven consecutive patients.
