Right ventricular outflow tract tachycardias comprise a subgroup of idiopathic ventricular tachycardias that occur in the absence of structural heart disease. Twelve-lead surface electrocardiography shows a left bundle branch block morphology and an inferiorly-oriented frontal axis during tachycardia. Non-sustained nature of arrhythmia and structure of the outflow tract makes catheter ablation of focal arrhythmia origin difficult. Herein, we presented ablation of right ventricular outflow tract tachycardia in a 32-year-old male patient using a new, simplified technique, described by Saleem et al., for three-dimensional mapping of the outflow tract. The patient was admitted with tachycardia of left bundle branch block with inferior axis morphology. In this technique, a spiral multipolar catheter was positioned in the right ventricular outflow tract and served as a guide for mapping and ablation. The patient was asymptomatic in the first and third months of the procedure.
右心室流出道心动过速是特发性室性心动过速的一个亚组，发生于无结构性心脏病的情况下。十二导联体表心电图显示心动过速时呈左束支传导阻滞形态且额面电轴向下。心律失常的非持续性以及流出道结构使得对局灶性心律失常起源进行导管消融变得困难。在此，我们介绍了一位32岁男性患者右心室流出道心动过速的消融情况，采用了Saleem等人描述的一种用于流出道三维标测的新的简化技术。该患者因呈左束支传导阻滞伴下轴形态的心动过速入院。在这项技术中，将一个螺旋多极导管置于右心室流出道，作为标测和消融的引导。该患者在手术的第一个月和第三个月均无症状。
