目的 探讨射频消融 (RFCA)对儿童阵发性室上性心动过速 (PSVT)的治疗价值。方法 连续收集 13例PSVT患者 ,通过标准 12导联体表ECG和心内电生理检查确定PSVT类型和标测消融靶点 ,然后施行RFCA。结果 房室折返型心动过速 (AVRT) 10例 ,房室结折返型心动过速 (AVNRT) 3例 ,其中左侧游离壁旁道 8例 ,右侧游离壁旁道 2例 ,房室结双径路 3例。RFCA成功率 10 0 %。 1例AVNRT患者发生一过性I度AVB ,1例AVRT 3个月时复发再次消融成功 ,未再复发。结论 RFCA治疗儿童PSVT安全、有效、成功率高 ,并发症少、复发率低。
Objective To investigate the therapeutic value of radio frequency ablation (RFCA) in children with paroxysmal supraventricular tachycardia (PSVT). Methods Thirteen patients with PSVT were consecutively collected. PSVT type and target of ablation were determined by standard 12-lead surface ECG and intracardiac electrophysiological examination. RFCA was then performed. Results There were 10 cases of atrioventricular reentrant tachycardia (AVRT) and 3 cases of atrioventricular nodal reentrant tachyarrhythmias (AVNRT), including 8 cases of the left aortic wall and 2 cases of the aortic wall in 2 cases, Double path in 3 cases. RFCA success rate 100%. One case of AVNRT patients with transient I degree AVB, 1 case of AVRT 3 months after recurrence again ablation success, no recurrence. Conclusion PSCA is safe and effective in treating pediatric patients with RFCA, with high success rate, fewer complications and low recurrence rate.
