P-wave dispersion for predicting maintenance of sinus rhythm after cardioversion of atrial fibrillation.
P-wave measurements and left atrial function were investigated to predict the maintenance of sinus rhythm after cardioversion of atrial fibrillation. Left atrial dimension <45 mm (p = 0.02) and P-wave dispersion <46 ms (p <0.001) were independent predictors of sinus rhythm maintenance, with a sensitivity of 89% and 96%, respectively. Duration of atrial fibrillation, maximum P-wave duration, and no spontaneous echocardiographic contrast were also univariate predictors.
