Why the study?
Does an upgrade to biventricular pacing improve physical performance, symptoms, and cardiac function in patients with conventional pacemakers and severe heart failure?

Supports BVP upgrade in severe HF with dominant RV pacing; extends CRT evidence to paced-rhythm subgroups.
Does an upgrade to biventricular pacing improve physical performance, symptoms, and cardiac function in patients with conventional pacemakers and severe heart failure?
Upgrading to biventricular pacing significantly improves physical performance, symptoms, and pro-BNP levels in heart failure patients with a dominant paced rhythm from a conventional pacemaker.
