Our goal was to determine what drugs are most efficacious for controlling the ventricular rate in patients with atrial fibrillation. ⋯ The calcium-channel blockers verapamil or diltiazem, or select beta-blockers are efficacious for heart rate control at rest and during exercise for patients with atrial fibrillation without a clinically important decrease in exercise tolerance. Digoxin is useful when rate control during exercise is less a concern.
