INR value achived between 2,5-3,5). We evaluated the results in relation to age, duration of AF, size of left atrial, left ventricular ejection fraction, and Joules delivered. Results: conversion to sinus rhythm occured in 82 pts (87%) with a mean 2,2±1,7 shocks and effective Joules of 180±92. With initial Joules of 50 success was achieved in 28/94 pts. Of 66 pts receiving cumulative energy 150 Joules, CV was successful in 27/66, of 39 pts receiving cumulative energy 350 Joules, CV was

By logistic regression, predictor of success of low-energy shock (50 J) was shorter duration of AF (r=0,51; p<0,01). There were no differences in results related to age, left atrial size and left ventricular ejection fraction. Conclusions: 1. The biphasic shocks for external CV of AF are effective and safe procedure. 2. The energy of 350 J is significantly more effective than 50, and 150 J, and should be considered for CV as the initial energy in pts with longer AF duration. 3. Pts with shorter duration of AF have a higher probability for successful CV with low energy. Introduction: aim of this study was to evaluate the efficacy and the impact on quality of life of a new ablative approach on the right atrium in patients with atrial fibrillation.
