在最近数年中,射频电流消融术发展迅猛,并已成为治疗房室结折返性心动过速(AVNRT)的主要手段。早有报导认为房室结快径路消融术疗效比较满意,但是,最近房室结慢径路消融术正在逐步取代快径路消融术,因为慢径路消融术的成功率达到了90％～100％,并且,导致房室传导阻滞(AVB)的危险性小。射频消融的效果有赖于与消融电极相接触的组织所接受的热量,包括直接的电产生的热量及间接传导的热量,因此,只有温度是射频消融效果的基础。电极与组织接触面的温度可以更可靠、更
In recent years, RF current ablation has developed rapidly, and has become the treatment of atrioventricular nodal reentrant tachycardia (AVNRT) the main means. It has long been reported that atrioventricular junctional fast pathway ablation is satisfactory, however, recently, atrioventricular node ablation is gradually replacing fast track ablation because the success rate of slow path ablation reached 90% to 100%, and , Resulting in a small risk of AVB. The effect of radiofrequency ablation depends on the amount of heat received by the tissue in contact with the ablation electrode, including the heat generated by direct electricity and the amount of heat indirectly transmitted. Therefore, only temperature is the basis for radiofrequency ablation. Electrode and tissue contact surface temperature can be more reliable, more
