[Predictors of efficacy initial low energy of external rectilinear biphasic cardioversion in persistent atrial fibrillation].

Unlabelled: Rectilinear biphasic cardioversion (Bi-DC) has been shown to be very effective for restoration of sinus rhythm in patients with persistent atrial fibrillation (AF). There is, however, limited information on factors influencing effectiveness of the initial energy of 50 J for Bi-DC of atrial fibrillation.

Aim Of The Study: Evaluation of efficacy of 50 J shock of Bi-DC for restoration sinus rhythm and development of point score system to predict high conversion rate of 50 J shock in persistent atrial fibrillation.
