Key result
Rhythm control shows no benefit over rate control as primary therapy for persistent AF.
Why the study?
Although rhythm-control strategies for atrial fibrillation have plausible benefits, recent randomized trials have not shown their superiority over rate-control strategies.

Rate control acceptable as primary strategy in persistent AF; reinforces trial data but leaves optimal patient selection open.
Lim et al. (2004) conducted a review in Atrial fibrillation. Rate control vs. Rhythm control was evaluated. Recent randomized trials have failed to demonstrate the superiority of rhythm control over rate control, establishing rate control as an acceptable primary approach for persistent atrial fibrillation.
