In this paper, Singh and his colleagues from the MADIT-CRT study looked at the influence of left ventricular lead position on responses to therapy in that trial. MADIT-CRT was a randomized clinical trial of patients with indications for an ICD New York Heart Association (NYHA) class I or II heart failure and a QRS duration > 130 msec.
