Paroxysmal atrial fibrillation. A common but neglected entity.

Paroxysmal atrial fibrillation is an extremely common form of atrial fibrillation seen by most physicians. Despite making up more than 40% of the cases of atrial fibrillation, its management continues to be neglected in the medical literature. Many of the recent large-scale prospective trials have excluded these patients. Limited data suggest that paroxysmal atrial fibrillation should be treated in a similar fashion as chronic atrial fibrillation.
