We present a patient who had a wide QRS tachycardia; it was initially difficult to determine whether it was superventricular tachycardia (SVT) or ventricular tachycardia (VT). By some criteria (sinus capture beats, pseudo-δ waves and wide QRS) the patient's ECG was suggestive of VT of epicardial origin. On the coronary angiogram it was found that this patient had significant coronary artery disease. He was stented with three stents and later had a full electrophysiological study .We present here the ECGs and the differential diagnosis and a brief review of the diagnostic features of epicardial VT.
我们介绍一位患有宽QRS心动过速的患者；最初很难确定其是室上性心动过速（SVT）还是室性心动过速（VT）。根据一些标准（窦性夺获搏动、假性δ波和宽QRS），患者的心电图提示为心外膜起源的VT。冠状动脉造影显示该患者患有严重的冠状动脉疾病。他接受了三个支架置入术，随后进行了全面的电生理研究。我们在此展示心电图、鉴别诊断以及对心外膜VT诊断特征的简要综述。
