宽QRS波心动过速可以是室性的,也可以是室上性的,其正确的鉴别诊断对临床治疗十分重要.过去人们着重注意QRS波呈右束支阻滞(RBBB)型的室性与室上性心动过速的鉴别诊断,而呈左束支阻滞(LBBB)型的心动过速的心电图鉴别诊断资料却很少。尽管有人采用分析V导联QRS形态、QRS电轴、QRS时限以及房室分离等以鉴别LBBB型室速(VT)与室上速(SVT),但近期文献报道仍有不少病例被误诊。本文回顾性分析了118例LBBB型宽QRS心动过速的12导联体表心电图,并总结出鉴别诊断
Wide QRS tachycardia can be ventricular or supraventricular, the correct differential diagnosis of clinical treatment is very important in the past people pay attention to QRS wave was right bundle branch block (RBBB) type of ventricular And supraventricular tachycardia in the differential diagnosis, and left bundle branch block (LBBB) type of tachycardia ECG differential diagnosis of data is rare. Although the analysis of V-lead QRS morphology, QRS axis, QRS time limit and atrioventricular septum were used to identify LBBB VT and SVT, many cases have been misdiagnosed recently. This retrospective analysis of 118 cases of LBBB wide QRS tachycardia 12 lead body surface ECG and concluded that the differential diagnosis
