射频消融治疗室上性心动过速的临床疗效评价

采用射频电流导管消融（ＲＦＣＡ）治疗室上性心动过速（ＳＶＴ）５１９例，总成功率为９５．０％（４９３／５１９）。其中旁道参与的ＳＶＴ３７９例（共３８４条旁道），离断３７５条，成功率（９７．７％）；房室结折返性心动过速１３４例，阻断慢径成功率９４．７％（１２６／１３３）；房性心动过速６例，成功４例，成功率６６．７％。８例患者出现并发症。随访１～５２月，２４例ＳＶＴ复发（４．６％），再次接受ＲＦＣＡ后均获成功。

Evaluation of Effects of Radiofrequency Current Ablation on Treating Supraventricular Tachycardia

Five hundred and nineteen cases of supraventricular tachycardia(SVT )were treated by radiofrequency current ablation(RFCA) with a total success rate of 95.0%,Among them,379 cases of SVT were caused by atri oventricular accessory pathway(AP),375 APs were successfully ablated with the success rate of 97.7%(375/384);In 134 patients with atrioventricular nodal reentrant tachycardia(AVNRT),the solw pathways were successfully abolished in 94.7% of them(126/133 cases);4 out of 6 patients(66.7%)with atrial tachycardia succeeded in RFCA. Complications occured in 8 patients. During 1～52 monthes follow-up period,SVT recured in 24 patients(4.6%)and was permanently eliminated by reapplication of RFCA. It was concluded that RFCA was a highly valuable non-drug threapy for SVT with high success rate,few complications and low recurrency rate.
