NCT01035489
First received: December 17, 2009

Last verified: May 2011
  Purpose

In heart failure patients we hypothesised that right ventricular high posterior septum is superior to right ventricular apex in CRT and DDD pacemaker. In two separate trials we prospectively randomized the right ventricular lead placement to find evidence of differences in heart failure symptoms (NYHA-class), 6 minute hall walk and echocardiographic measurements of reverse remodelling and dyssynchrony.
