射频消融治疗快速心律失常428例总结

目的：报告射频消融术（RFCA）治疗快速心律失常的经验。方法：分析本院428例RFCA患者资料，其中房室结折返性心动过速（AVNRT）127例，房室折返性心动过速（AVRT）261例，特发性室性心动过速（IVT）28例，阵发性心房扑动（PAF）9例，房性心动过速（AT）3例。结果：消融总成功率96．9％（其中AVNRT97．6％，AVRT97．4％，IVT82．1％，PAF77．8％，AT100％），总复发率4．6％（其中AVNRT2．4％，AVRT4．3％，IVT 17．4％，PAF 14．3％），并发症发生率o．9％，无致命并发症出现。结论：RFCA治疗快速心律失常成功率高，并发症少，是安全有效的根治方法。

Experience of treating the patients with tachycardia by radio-frequency catheter ablation

To report the experience treating tachyeardia by radio-frequency catheter ablation(RFCA).Meth- ods:The 428 data of patients with tachycardia treating by RFCA were analyzed.Among them atrial-ventricular node reentrant tachycardia(AVNRT)127 was cases,atrial-ventricular reentrant tachycardia(AVRT)was 261 cases,idio- pathic ventrieular tachycardia(IVT)was 28 cases,paroxysmal atrial flutter(PAF)was 9 cases,and atrial tachycardia (AT)was 3 cases.Results:The total successful rate of treating tachycardia by RFCA was 96. 9%.By each sub-group, the successful rate was 97. 6% for AVNRT,97. 4% for AVRT,82. 1% for IVT,77. 8% for PAF,100% for AT. The total recurrence rate was 4. 6%.For each sub-group,the recurrence rate was 2. 4% for AVNRT,4. 3% for AVRT,17. 4% for IVT,14. 3% for PAF.The complication rate was 0. 9%,no fatal complication appeared.Conclu- sion:There are high successful rate,less complications for treating the tachycardia by radio-frequency catheter abla- tion.
