What are the three main management strategies described for atrial fibrillation?

• A. Rate control, Anticoagulation, and Rhythm control
• B. Rate control
• C. Anticoagulation
• D. Rhythm control

Answer: (A)

Atrial fibrillation is managed by three main aims: slow the heart rate to prevent tachycardia-related problems, prevent stroke, and restore or maintain normal rhythm when possible. Rate control is achieved with medications like beta-blockers or non-dihydropyridine calcium channel blockers (and sometimes digoxin), which keep the ventricular rate under control and improve symptom burden. Rhythm control focuses on reestablishing and maintaining sinus rhythm through electrical cardioversion or antiarrhythmic drugs, with catheter ablation as an option for some patients. Anticoagulation addresses stroke risk, chosen based on a patient’s stroke risk score (such as CHA2DS2-VASc) and tailored to contraindications, to reduce the chance of embolic events from atrial fibrillation. The other options describe only one aspect of management, whereas the best answer reflects this three-pronged approach.
