虽然射频电流导管消融治疗房室结折返性心动过速的常见方式是在慢径路,而不是在快径路部位进行,但必须理解慢径路的选择性消融。由于选择性消融慢径路比消融快径路在理论上有诸多优点,在治疗房室结折返性心动过速时,消融慢径路的实践已成为标准治疗方案。选择性消融慢径路在理论上的优点包括:(1)选择性消融慢径路的心房部位通常在远离希氏束电图记录部位的冠状窦
Although RFA catheter ablation is a common approach to atrioventricular nodal reentrant tachycardia rather than fast pathway, it is important to understand the selective ablation of slow pathway. Because selective ablation of slow pathways has many advantages in theory as compared to ablation of fast pathways, the practice of ablating slow pathways has become the standard treatment for the treatment of atrioventricular nodal reentrant tachycardia. The theoretical advantages of selective ablation of the slow pathway include: (1) Selective ablation of slow atrium in the slow pathway usually occurs at a distance from the coronary sinus
