[Effectiveness of D,L-sotalol in post-ablative atrial arrhythmias in patients with atrial fibrillation treated with radiofrequency ablation].

Unlabelled: Left atrial tachycardia is the most common arrhythmia developing after pulmonary vein (PV) isolation in patients with atrial fibrillation.

Aim: To compare the clinical effectiveness of class Ic propafenone and class III D,L sotalol in antiarrhythmic treatment of post-ablation left atrial tachycardias.

Methods And Results: A total of 75 consecutive patients with an age of 55.

Pulmonary vein isolation without left atrial mapping.

Background: One of the crucial points during in most approaches developed for ablation of atrial fibrillation (AF) is the ability to identify the pulmonary vein (PVs) and to accurately locate their ostia.

Objectives: The purpose of this case series was to investigate a simplified method for fusion of the multislice computer tomography (CT) derived 3D dataset with the electroanatomical map in order to facilitate the mapping procedure.

Methods: In 5 consecutive patients (4 male) referred for catheter ablation of symptomatic drug-refractory paroxysmal atrial fibrillation contrast enhanced computer tomography was performed before the procedure and imported into an electroanatomical mapping system (Carto XP) using CartoMerge Image Integration Module.
