A 57-year-old man with prior anteroseptal myocardial infarction underwent catheter ablation of ventricular tachycardia (VT) exhibiting a left bundle branch block QRS morphology. After failed left ventricular ablation, catheter ablation from the right ventricle (RV) eliminated the VT. An RV voltage map demonstrated an area of low voltage around the successful ablation site that likely allowed for a VT substrate.
一位 57 岁男性，曾患有前间隔心肌梗死，因表现出左束支传导阻滞 QRS 形态的室性心动过速（VT）而行导管消融术。左心室消融失败后，从右心室（RV）进行导管消融消除了 VT。RV 电压图显示成功消融部位周围存在低电压区域，这可能为 VT 基质提供了条件。
