Techniques to Improve and Confirm Pulmonary Vein Isolation

Atrial fibrillation is the most common acquired arrhythmia and is increasing in frequency as the population ages.

The strategy used to treat atrial fibrillation largely rests on the extent of symptoms in an individual patient. This review will focus on ablation for atrial fibrillation and efforts to improve the success of the procedure.
