e0663 Initial experience of synchronised electrical cardioversion for atrial fibrillation after bipolar radiofrequency ablation Maze operation

Initial energy for external electrical cardioversion of atrial fibrillation.

OBJECTIVE To investigate the initial energy level required for electrical cardioversion of atrial fibrillation (AF). METHODS We studied patients undergoing electrical cardioversion in the 1st Multicenter Trial of SOCESP. Patients were divided into 2 groups according to the initial energy level of electrical cardioversion: 100J and >/=150J. We compared the efficacy of the initial and final sho...

surgical radiofrequency maze iii ablation for treatment of atrial fibrillation during open heart surgery

background: atrial fibrillation is a common arrhythmia in patients with rheumatic mitral and other valve diseases who are candidates for valve repair surgeries. conversion of rhythm to sinus has positive effects on quality of life and lower use of medications. the aim of this clinical study was to evaluate the effectiveness of the radiofrequency ablation maze iii procedure in the treatment of a...

Radiofrequency ablation for atrial fibrillation

Electrical and pharmacologic cardioversion for atrial fibrillation.

This article describes electrical and pharmacologic cardioversion for atrial fibrillation and discusses indications for cardioversion and management of pericardioversion anticoagulation. Finally, management strategies are offered for immediate recurrence of atrial fibrillation and cardioversion failure.

Atrial Fibrillation after Radiofrequency Ablation of Type I Atrial Flutter.

Typical atrial flutter (AFL) or type I AFL is the most common type of macroreentrant atrial tachycardia. Its prevalence increases with age and is more common in men. Ablation of the cavo-tricuspid isthmus (CTI), a critical part of the circuit, is safe and highly effective. Despite the long-term efficacy of this therapy, a significant proportion of patients undergoing CTI ablation will develop a...
