Filter by:The purpose of this study is to determine whether catheter ablation is more effective than antiarrhythmic drugs in the early stages of paroxysmal atrial fibrillation. In all the patients a subcutaneous loop recorder will be implanted.
The purpose of this study is 3 fold:- 1. To compare the efficacy and complication rates of 2 widely used methods, conventional irrigation tip ablation catheter (LASSO) and Ablation Frontiers ablation technology, of AF ablation for PAF. 2. To evaluate the Reveal XT ILR as a long term accurate AF monitoring device as compared to the 'gold standard' DDD pacemaker Holter. 3. To accurately evaluate, by continuous rhythm monitoring for 1 year, the efficacy of AF ablation therapy for PAF.
The purpose of this study is to accurately investigate the efficacy of dronedarone in maintaining sinus rhythm and decreasing AFB in patients with paroxysmal atrial fibrillation as compared with placebo. This has never previously been performed using pacemaker Holter monitoring which provides detailed information of atrial arrhythmia patterns the entire study period. Additionally detailed patient symptom self assessment and questionnaires will be collected. The study design will be double blinded crossover with each phase lasting 3 months.
Randomized comparison between 2 techniques of circumferential pulmonary vein ablation in paroxysmal atrial fibrillation: Primary anatomical ablation with secondary closure of possible electrical gaps versus primary electrophysiological ablation at the sites of atrio-venous electrical breakthroughs with secondary circumferential ablation around the pulmonary vein orifice
