Atrial fibrillation ablation: State of the art

Atrial fibrillation ablation: State of the art: "Atrial fibrillation (AF) is a common and recurrent arrhythmia that can result in significant morbidity and mortality [1]. Pharmacological therapy used to control rate or to achieve and maintain normal sinus rhythm is of limited efficacy, and can result in serious side effects including proarrhythmia and death [2-4]. Although ablation of the AV node and implantation of a permanent pacemaker can provide effective rate control, this loss of atrioventricular synchrony renders the patient dependent on the pacemaker and will require lifelong anticoagulation therapy.
