A 45-year-old woman underwent radiofrequency ablation (RFA) for symptomatic idiopathic left ventricular tachycardia (ILVT). The clinical arrhythmias had two different patterns, a wide QRS tachycardia with right bundle branch block (RBBB) and left axis deviation (LAD) and another with RBBB and right axis deviation (RAD). The electrophysiology study localized the origin of tachycardias to the midinferior and superior ventricular septum, respectively. RFA terminated successfully ILVT with RBBB and LAD morphology, but another pattern could not be ablated. Noncontact mapping revealed the earliest site of activation at the superior septum. RFA at this site terminated successfully ILVT with RBBB and RAD.
一名45岁女性因症状性特发性左心室心动过速（ILVT）接受了射频消融（RFA）治疗。临床心律失常有两种不同模式，一种是宽QRS心动过速伴右束支传导阻滞（RBBB）和左轴偏移（LAD），另一种是伴RBBB和右轴偏移（RAD）。电生理研究将心动过速的起源分别定位到室间隔中下和上部。RFA成功终止了具有RBBB和LAD形态的ILVT，但另一种模式无法消融。非接触式标测显示上间隔为最早激动部位。在此部位进行RFA成功终止了具有RBBB和RAD的ILVT。
