The aim of the study is to see if biventricular pacemakers offer any advantage over conventional pacemakers in patients with heart failure who require pacemakers. The endpoints will be the 6 minute walking distance along with markers of cardiovascular function.

The investigators' hypothesis is that biventricular pacing is preferable to conventional pacing in these heart failure patients.
