1942年Dressler首先报告一例心肌梗塞(以下简称MI)病人,梗塞图形被束支传导阻滞所掩盖,由于出现偶发性呈QR型室性期前综合波(以下简称VPC)而得到确诊。Bisteni等指出右侧心前导联出现病理性Q波,为室间隔中1/3区MI的证据,而室间隔下1/3区MI在呈正常室内传导时不易诊断,因向后指向的梗塞向量,可被左室游离
In 1942, Dressler first reported a case of myocardial infarction (hereinafter referred to as MI), the infarction pattern was covered by bundle branch block, due to the occurrence of occasional QR-ventricular pre-synthesis wave (hereinafter referred to as VPC) and was diagnosed. Bisteni pointed out that the right side of the front of the pathological Q-wave pathological evidence of interventricular septal 1/3 MI evidence, and 1/3 of the inter-ventricular septal MI in normal indoor conduction is not easy to diagnose due to backward-oriented infarction Vector, can be left ventricular free
