Is rhythm control better than rate control for new-onset atrial fibrillation in the emergency department?

In patients with new-onset atrial fibrillation and symptom onset within 48 hours, rhythm control is preferred over rate control if the patient is younger than 65 years. For patients with congestive heart failure, valvular heart disease, hypertension, or permanent atrial fibrillation, rate control remains the favored strategy.
