Risk of Arrhythmia Recurrence After Successful Ablation of Lone Atrial Fibrillation.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is difficult to treat.1 It may present with a variety of symptoms ranging in severity from mild to disabling.2 While some patients get diagnosed at the time of a routine visit and are not aware of their arrhythmia, others may present with palpitations, chest discomfort, dyspnea and syncope. Atrial fibrillation is commonly associated with cardiac and extra cardiac conditions such as valve disease, left ventricular dysfunction, hypertension, diabetes, pulmonary and thyroid disease.3
