A 57-year-old man presented with palpitations and dizziness for one day. He reported a history of similar short-lasting, self-limiting episodes in the past. Evaluation showed a hemodynamically stable, ongoing monomorphic ventricular tachycardia (VT) with positive concordance in the precordial leads and inferior axis. A structurally normal heart was seen on echocardiography. The VT was cardioverted to normal sinus rhythm with a biphasic 100-J direct-conversion shock under mild sedation, only to spontaneously start over again. In view of the patient's structurally normal heart, a previous history of similar complaints in the past, and no obvious trigger including ischemia for VT, he subsequently underwent an electrophysiology study (EPS).
一名57岁男性因心悸和头晕就诊，症状持续一天。他报告既往有过类似的短暂、自限性发作史。评估显示血流动力学稳定，持续性单形性室性心动过速（VT），胸前导联和下轴呈正向一致性。超声心动图显示心脏结构正常。在轻度镇静下，通过100 J双相直接转换电击将室性心动过速转复为正常窦性心律，但随后又自行复发。鉴于患者心脏结构正常、既往有类似症状史且无明显的室性心动过速触发因素（包括缺血），他随后接受了电生理检查（EPS）。
