The surface electrocardiogram (ECG) is a useful tool to help identify the sites of origin of ventricular tachycardia (VT). Despite such limitations as chest wall deformity and metabolic and drug effects, the analysis of the QRS morphologic patterns and vectors can discern the site of activation of myocardium. There have been described numerous reports about ECG features of idiopathic left- and right-ventricular VT. In this review, we summarized typical ECG characteristics according to the VT sites of origin based on previous reports, with anatomical considerations of the left and right ventricles, including the outflow tracts and epicardium.
体表心电图（ECG）是帮助识别室性心动过速（VT）起源部位的有用工具。尽管存在胸壁畸形、代谢及药物影响等局限性，但对QRS形态模式和向量的分析仍可辨别心肌激活部位。关于特发性左、右心室VT的心电图特征已有大量报道。在本综述中，我们根据既往报道，结合左、右心室（包括流出道和心外膜）的解剖学因素，总结了根据VT起源部位的典型心电图特征。
