Radiofrequency (RF) catheter ablation has become the treatment of choice for a variety of supraventricular tachycardias. Autonomic dysfunction may occur during application of RF current; these abnormalities resolve quickly when current delivery is terminated. We present a case of sinus node arrest and AV block in a 69-year-old woman induced by RF catheter ablation of an AV nodal slow pathway. The proposed mechanisms are a Bezold-Jarisch-like phenomenon or paradoxical activation of cardiac C fibres by direct neural sympathetic stimulation or RF-induced myocardial injury. Based on a review of previously published reports, autonomic effects of RF ablation are discussed.
射频（RF）导管消融已成为治疗多种室上性心动过速的首选方法。在施加射频电流时可能会出现自主神经功能障碍；当电流输送终止时，这些异常会迅速消失。我们报告一例69岁女性在射频导管消融房室结慢径路时诱发的窦性停搏和房室传导阻滞病例。推测的机制是贝佐尔德-雅里什样现象或直接神经交感神经刺激或射频诱导的心肌损伤导致心脏C纤维的反常激活。基于对先前发表报告的回顾，讨论了射频消融的自主神经效应。
