对室性心动过速与室上性心动过速伴室内差异性传导的鉴别,向来存在着分歧。但自 Marriott 和 Wellens 等提出一些心电图判断标准后,约90％QRS 波宽的心动过速可根据体表12导联心电图确定其激动起源部位。本文报道体表心电图表现的一种新征象,迄今尚未见诸报道。倘若在QRS 宽的心动过速中出现,指明其心动过速是室性心动过速而不是室上性心动过速伴室内差异性传导。胸前导联 QRS 波→致性是指 V_1—V_6的 QRS 波均向上(正向一致性)或均向下(负向一致性),但不论是前者
Disagreements have always existed on the identification of ventricular tachycardia and supraventricular tachycardia with differential conduction in the room. However, since Marriott and Wellens put forward some ECG criteria, about 90% QRS wave width tachycardia can be based on the body surface lead 12 ECG to determine the location of their excitement. This article reports a new appearance of body surface electrocardiogram, which has not been reported yet. If present in a QRS wide tachycardia, indicate that the tachycardia is ventricular tachycardia rather than supraventricular tachycardia with indoors differential conduction. Thoracic lead QRS wave → induced refers to V_1-V_6 QRS wave both upward (forward consistency) or both downward (negative consistency), but whether the former
