Model Details: A total of 100 patients with persistent，in whom successful RF ablation of slow pathway or accessory pathway was performed. Patients with atrial fibrillation, structural heart disease, ventricular arrhythmias, impaired left ventricular systolic function or on antiarrhythmics were excluded. All the patients had echocardiographic study before ablation 、1 day and 1 months after ablation.
