Original research article: Increased baseline ECG R-R dispersion predicts improvement in systolic function after atrial fibrillation ablationDOI: 10.1136/openhrt-2018-000958 Keywords: atrial fibrillation, cardiomyopathy, left ventricular function, R-R dispersion Abstract: Atrial fibrillation (AF) is associated with left ventricular (LV) systolic dysfunction which may improve after AF ablation. We hypothesised that increased ventricular irregularity, as measured by R-R dispersion on the baseline ECG, would predict improvement in the left ventricular ejection fraction (LVEF) after AF ablation
