The risk of stroke is increased fivefold in individuals with atrial fibrillation. The degree of increased risk may be substantial, depending on the presence of additional risk factors. Atrial fibrillation is often treated with medications to slow the heart rate to a normal range or to correct the heart rhythm to normal sinus rhythm. Synchronized electrical cardioversion can also be used to convert AF to a normal heart rhythm. Surgical and catheter-based ablation may be used to prevent recurrence of atrial fibrillation in some individuals.
