Objective Identification of patients at risk for atrial fibrillation (AF) recurrence with using simple and objective parameters may be helpful in tailoring the treatment. In this study, we investigated whether E/(Ea×Sa) Ea/(Aa×Sa) could a predictor AF after cardioversion. (E = early diastolic transmitral velocity, Ea mitral annular Aa late Sa systolic velocity). Methods total, 127 persistent were evaluated study 73 included according to criteria. Sinus rhythm (SR) was achieved 70 electrical direct‐current E, Sa, Ea, determined medial lateral site average values obtained. calculated (medial, lateral, average). Heart rate followed an electrocardiography (ECG) monitor 12‐lead ECG first week month. Results At one month, 53 (75.7%) SR, whereas 17 (24.3%) reverted AF. According precardioversion medial, (P ≤ 0.01 all indices), 24‐hour echocardiographic evaluation average, indices significantly higher group than SR group. Furthermore, ROC analysis showed that predict recurrence. The AUC range from 70% 81% parameters). subgroup patients, E/Ea ratio between 8 15, novel 72% 86% 0.02 Conclusions We found are predictors
