Radiofrequency Ablation of Atrial Fibrillation and Atrial Flutter: Who and When?

Conference paper


While typical atrial flutter (AFL) is a characteristic macroreentrant atrial tachycardia originating in the right atrium, atrial fibrillation (AF) is triggered in most subjects by arrhythmogenic foci localized in the myocardium around pulmonary veins and maintained by functional reentrant circuits in the left atrial myocardium. However, there is a close relationship between the two arrhythmias. They often coexist in the same patient and may degenerate into each other [1]. The reasons for this coexistence are not clear. It is possible that pulmonary venous triggers also initiate AFL or convert AFL into AF [2].
