Radiofrequency (RF) catheter modification of the sinus node appears to be a promising therapeutic modality for the treatment of inappropriate sinus tachycardia. Modification, as opposed to total obliteration, of the atrial pacemaker requires precise localization of the sinus node. This has been successfully achieved with a multicatheter approach guided by intracardiac echocardiography. This article describes the first clinical use of a tridimensional nonfluoroscopic mapping system to guide successful RF modification of the sinus node in two cases of inappropriate sinus tachycardia. This system simplifies the current approach and greatly reduces the fluoroscopy time.
射频（RF）导管改良窦房结似乎是治疗不适当窦性心动过速的一种有前景的治疗方式。与完全消除心房起搏器不同，改良需要精确确定窦房结的位置。这已通过心腔内超声心动图引导的多导管方法成功实现。本文描述了在两例不适当窦性心动过速病例中首次临床使用三维非荧光透视标测系统指导成功进行窦房结射频改良。该系统简化了当前方法并大大减少了透视时间。
