Choosing the Right Pacing Mode in Heart Failure - The CHOICE Trial (CHOICE)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

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.
