The Selvester QRS (S\u2010QRS) score is an electrocardiogram\u2010based assessment that reportedly reflects myocardial scar\/damage. We evaluated the predictability of S\u2010QRS score for the recovery of left\u2010ventricular ejection fraction (LVEF) in persistent AF (PeAF) patients with LVSD undergoing catheter ablation (CA).<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>CA was performed in 51 PeAF patients with reduced LVEF (&lt;40%); S\u2010QRS scores were measured after restoration of sinus rhythm.

In univariate\/multivariate analyses, S\u2010QRS score was an independent predictor of LVEF normalization. In the receiver operating characteristic curve, the cut\u2010off value of S\u2010QRS score was 2 points for prediction of the LVEF normalization (AUC\u00a0=\u00a00.79).
