４７例室性心动过速发作时心电图特征：ＱＲＳ波形态呈右束支阻滞图形１４例，左束支阻滞图形１２例，非束支阻滞图形２１例；ＱＲＳ波宽度＞０．１４ｓ１４例，＜０．１３ｓ３３例，其中有房室分离２１例（２１／３３）．３３例曾作Ｘ线胸片、心脏Ｂ超等物理检查，证实有９例无明显器质性疾病。本资料结果提示：ＱＲＳ＜０．１３ｓ加房室分离可作为ＶＴ的诊断标准之一，而房室分离为ＶＴ与室上速（ＳＶＴ）合并室内差异传导的鉴别要点。
The electrocardiographic features of 47 patients with ventricular tachycardia were as follows: QRS wave pattern showed right bundle branch block pattern in 14 cases, left bundle branch block pattern in 12 cases, non-bundle branch block pattern in 21 cases, QRS wave width> 0.14s14 Cases, <0.13s33 cases, including atrioventricular septum in 21 cases (21/33). 33 cases had X-ray, B ultrasound and other physical examination confirmed 9 cases without obvious organic disease. The data results suggest that: QRS <0.13s plus atrioventricular separation can be used as one of the diagnostic criteria for VT, and atrioventricular separation for the VT and supraventricular tachycardia (SVT) differential indifference points indoor differentiation.
