导管射频消融治疗特发性室性心动过速的体会

Experience in Treatment of Idiopathic Ventricular Tachycardia by Radiofrequency Catheter Ablation

目的探讨应用导管射频消融（ＲＦＣＡ）治疗特发性室性心动过速的疗效。方法经皮穿刺左右侧股静脉右侧股动脉（起源于左室时），将多根６Ｆ或７Ｆ４极导管送至高位右房（ＨＲＡ）、房束（ＨＢＥ）、右室心尖（ＲＶＡ）、右室流出道（ＲＶＯＴ）或左室（ＬＶ），作短阵快速和程序刺激心室诱发ＶＴ，同步记录１２导联及心腔内各部位电图。结果除１例不能坚持ＲＦＣＡ外，成功１１例（９１．７％），另１例因疗效不满意改用导管心内膜直流电消融而获成功。结论术前诊断及靶点标测的准确性是ＲＦＣＡ治疗成功的关键。
