Catheter ablation for paroxysmal atrial fibrillation

Atrial fibrillation (AF) is the most commonly occurring arrhythmia, with a characterised pattern of progression. The many different presentations of AF and approaches to its management refect the complex nature of this condition. This article describes the overall management of a patient with lone paroxysmal AF, with a focus on pharmacological therapy and catheter ablation. In order to understand the therapeutic strategies employed, an appreciation of the pathophysiological processes involved in the development and perpetuation of AF is required. Ultimately, the driving force for any management strategy adopted should be determined by the symptoms experienced by the patient, and the effect that the arrhythmia has on their quality of life.
