Data are shown as mean±standard deviation or number (%) not otherwise specified.
AF = atrial fibrillation; AFL = atrial flutter; AT = atrial tachycardia; BMI = body mass index; DM = diabetes mellitus; IVSd = interventricular septal thickness at diastole; LA = left atrium; LVEDD = left ventricular end-diastolic dimension; LVEF = left ventricular ejection fraction.
*The blanking period is within 90 days after catheter ablation.
