Purpose of study: The main goal of the study was to determine the effectiveness of biphasic rectilinear shock during external cardioversion in patients with persistent atrial fibrillation (AF). An additional goal was to assess the factors which influence cardioversion success rate, in particular chest impedance.

Method: From a cohort of 244 patients, in whom a total of 439 external electrical cardioversions was performed using the Biphasic Defibrillator, data on the procedures performed between July 2001 and October 2005 were collected both retrospectively and prospectively and further statistically processed. Both individual and cumulative effectiveness of the shocks delivered in version to sinus rhythm (SR), the relation between impedance and success rate of version to SR, and the actual energy and current levels delivered by the defibrillator were studied.

Keywords: atrial fibrillation, biphasic cardioversion, chest impedance
