近年来,应用(RF)能源与可屈性大头电极,经心内膜直接消融阻断旁道,揭开了导管消融术治疗预激征合并快速性心律失常新的一章。RF 消融不需全麻、不产生气压伤,一般不导致心肌穿破,亦少诱发心律失常,故安全性高。阻断旁道的成功率在有经验的单位可达90％以上,故日渐成为本症非药物治疗的首选方法。施术前宜根据体表心电图δ波向量对旁道作出初步定位。然后分别在高位右房、右房下部、右室心尖及冠状窦内放置多极导管,进行系统电生理检查,左侧或右侧旁道分别在二、三尖瓣瓣环处放置可屈性导管,在左前、右斜透视下
In recent years, the use of (RF) energy and bulk head electrode, the direct endocardial ablation bypass block, opened a new chapter of catheter ablation for pre-excitation merge tachyarrhythmia. RF ablation without general anesthesia, does not produce barotrauma, generally does not lead to myocardial puncture, also less induced arrhythmia, it is safe. The success rate of blocking the bypass in an experienced unit up to 90% or more, it has become the preferred method of non-drug treatment of this disease. Before surgery should be based on the surface ECG δ wave vector to make a preliminary positioning of the bypass. Then placed in the high right atrium, the right atrium, the right atrium and coronary sinus placed multi-pole catheter, the system electrophysiological examination, the left or right bypass were placed in the two tricuspid valve annulus at the bendability Catheter, in the left front, right oblique perspective
