Lenient Rate Control Versus Strict Rate Control for Atrial Fibrillation. The Danish Atrial Fibrillation Randomised Clinical Trial

Treatment will be provided according to current guidelines and as such the algorithm for treatment will be differentiated based on the status of left ventricular ejection fraction. For participants with reduced left ventricular ejection fraction, beta-blockers (metoprolol and bisoprolol) will be the primary therapy. Secondary therapies may include digoxin or amiodarone. For participants with preserved left ventricular ejection fraction, the primary therapy will be beta-blockers (metoprolol and bisoprolol) or non-dihydropyridine calcium-channel blockers (verapamil) with secondary therapy consisting of digoxin or amiodarone. Pacing therapies, alone or with atrioventricular node ablation, are utilised as indicated in the view of the treating physician.
