Recovery of Left Ventricular Systolic Function and Atrial Fibrillation Recurrence after Restoration of Sinus Rhythm in Patients with Atrial Fibrillation

Overview

About this study

The objectives of this study are: (1) to analyze beat-to-beat variability and the variations of R-R interval to pre-preceding R-R interval (RRp/RRpp) ratio of left ventricular (LV) function by strain imaging (2D speckle tracking echocardiography) in patients with atrial fibrillation (AF) undergoing electrical cardioversion(ECV) or radiofrequency catheter ablation (RFCA) as a predictor of a recovery of LV function and volume after restoration of sinus rhythm , (2) to evaluate left atrial mechanics as a predictor of for AF recurrence after electrical cardioversion (ECV) or radiofrequency catheter ablation (RFCA)
