Methods The clinical data of 97 pediatrie patients with PSVT, who underwent RFCA in Sichuan Provincial People s Hospital from January 2009 to January 2013, were retrospectively analyzed? 65 male and 32 female were found in 97 pediatrie patients； the average of age and weight were (7. 1±1.8) years and (32. 4±8? 9) kg respectively； and they were followed up for (27±21) months? RFCA surgery treatmen was analyzed. ResuIts In this cohort, 66 cases (68?0%) were diagnosed with atrio-ventricular reentrant tachycardia (AVRT), which included 38 cases (57.6%) with left ventricular outflow and 28 cases (42.4%) with right ventricular outflow； and 31 cases (32. 0%) with atrio-ventricular nodal reentrant tachycardia (AVNRT) . The success of the RFCA was achieved in 95 patients (97.9%)； while recurrence occurred in 6 patients (6.2%) . However, after second ablation, all those 6 patients were not recurrence? In this co
