Radiofrequency ablation
RF applications were delivered with a maximal temperature of 43°C at the catheter tip (SmartTouch Navistar Thermocool catheter) and at the power between 25-50 watts. The primary end points during RF ablation were either complete elimination of areas with CFAE or conversion of AF to normal sinus rhythm (SR). When areas with CFAE were completely eliminated but the atrial arrhythmias persisted (organized atrial flutter or atrial tachycardia), they were subsequently mapped and ablated (occasionally in conjunction with ibutilide, 1 - 2 mgs intravenously over 10 minutes).
