(1) Predictors of AF disappearance. The significant predictive factor of AF disappearance was F-wave ≥ 0.1 mV
(2) Predictors of NSR. Significant predictive factors of electrical restoration of AF were F-wave ≥ 0.1 mV + AF history ≤ 3 years
(3) Predictors of NSR with A-wave. The significant predictive factor of mechanical restoration of atrial function was a left atrial diameter ≤ 55 mm. 95% CI, 95% confidence interval; AF, atrial fibrillation; LAD, left atrial diameter
