Atrial fibrillation is the commonest cardiac arrhythmia. While a number of established drug therapies are often successful in achieving satisfactory control, more recently radiofrequency catheter ablation has emerged as an effective therapy for patients with paroxysmal AF. ¬†However, the place of catheter ablation remains unclear with limited data comparing ablation with antiarrhythmic drug therapy as […]

A return to rhythm? PVI proves superior in low EF CHF

Atrio-ventricular node ablation has been used to treat symptomatic atrial fibrillation with poor rate control although these studies have contained few subjects with low ejection fractions. Biventricular pacing has recently been shown to be superior to right ventricular pacing following atrio-ventricular node ablation. […]
