摘要
作者采用40MHz的射频对6例预激综合征并阵发性室上性心动过速的患者分别行冠状窦消融和房室结改良术,2例有效。初步认为冠状窦消融有一定局限性。此与射频消融作用局限需精确定位以及旁道远离冠状窦内标测电极有关。用房室结改良术或用吸附电极导管有望提高治疗预激综合征的疗效。
This article reports the results of transcatheter ablation using 40 MHz radiofrequency in six patients with WPW syndrome. Premary success was achieved after catheter ablation of accessory pathway in coronary sinus in one case and after modification of atrioventricular nodal conduction in another. The results showed that transcatheter ablation of accessory pathway in coronary sinus had a limitation. The methodology of catheter ablation of WPW syndrome was discussed in this article. In order to obtain an excellent result, using modification of atrioventricular nodal conduction or suction electrode catheter would improve the therapeutic effect in catheter ablation of WPW syndrome.
