| 摘 要： | 为探讨心内结构异常合并房室旁道患者射频消蚀的难易程度，对射频消蚀８例先天性心脏病Ｅｂｓｔｅｉｎ畸形（Ⅰ组）与２０例合并右侧房室旁道心内结构正常者（Ⅱ组）进行观察。结果显示：两组心动过速的心室率、旁道的前传和逆传不应期均相近，差异无显著性；两组消蚀导管的选择与操作过程无不同之处，其总操作时间、Ｘ线投照时间和放电次数分别为：１１０±６３ｍｉｎＶＳ１０３±５５ｍｉｎ、４５±２１ｍｉｎＶＳ３９±１７ｍｉｎ、６±４次ＶＳ６±３次，Ｐ均＞０．０５。且两组病例均一次消蚀成功。结果说明Ｅｂｓｔｅｉｎ畸形合并房室旁道的射频消蚀同样较易成功。手术操作需轻柔，对合并右心功能不全者应避免心动过速的诱发；倒“Ｕ”形导管塑形，可加强导管的稳定性。

| Abstract: | The comparison of radiofrequency catheter ablation(RFCA)of right-sided accessory pathways(APs)in patients with Ebstein's anomaly(group I)to normal heart(group II)was studied.The results showed there were not significantly difference in heart rate of tachycardia,anterograde and retrograde refractory period between group I and group II.APs all located in right posteroseptal and right posterolateral wall;RFGA was successfully performed in patients.There were not also difference in procedure time,fluoroscopy time and total energy application between two groups;no complication occured.These demonstrated it was not difficulity to perform RFCA in patients with Ebstein's anomaly and the characteristic of RFCA in Ebstein's anomly was disscussed. |
