Comparison of beta blocker and digoxin alone and in combination for management of patients with atrial fibrillation and heart failure.

In patients with atrial fibrillation (AF) and heart failure (HF), beta blockers and digoxin reduce the ventricular rate, but controversy exists concerning how these drugs affect prognosis in this setting. This study compared the effects of beta blocker and digoxin on mortality in patients with both AF and HF. In a single-center institution, patients with AF and HF seen between January 2000 and January 2004 were identified and followed until September 2007.
