为确定心动过速时异常传导与室性异位的鉴别诊断价值，对心动过速时QRS波群增宽患者的心动过速进行了回顾性分析，并用希氏束电确定心动过速的起始点。62例患者的70次持续性室性心动过速和60例患者的70次室上性心动过速时的异常传导可供研究。室性心动过速的起始性表现为QRS宽度大于0.14 S、心电轴左偏、QRS的某些形态特征和房室分离。在33次持续性心动过速中，只有4次出现由室性心动过速时分离的房室传导引起的俘获或融合的心动过速。
To determine the value of the ECG for differentiating aberrant conduction from ventricular ectopy, findings were retrospectively reviewed from patients with a widened QRS complex during tachycardia in whom the site of origin of tachycardia was determined by His bundle electrography. Episodes (70) of sustained ventricular tachycardia from 62 patients and 70 episodes of aberrant conduction during supraventricular tachycardia from 60 patients were available for study. Findings suggesting a ventricular origin of tachycardia were a QRS width over 0.14 s, a left axis deviation, certain configurational characteristics of QRS and an atrioventricular (A-V) dissociation. Capture or fusion beats resulting from A-V conduction of dissociated atrial complexes during ventricular tachycardia were seen during only 4 of 33 episodes of sustained tachycardia.
