Thirty-seven patients with acute myocardial infarction complicated by atrioventricular or bundle branch block, or a combination of both, has His bundle electrogram studies performed during their stay in the coronary care unit. The acute mortality of the 14 patients with a complicating bundle branch was 50%. Pump failure was the main cause of death. Three patients in this group had a prolonged H-V interval and one patient had a split blundle of His. The presence or absence of a prolonged H-V interval did not affect mortality in this group of patients. The acute mortality of the 16 patients with an inferior wall myocardial infarction was 6%. The H-V interval was normal in all but one of these patients. The atrioventricular block was caused by a proximal block in all cases. The acute mortality of the seven patients with an anterior wall myocardial infarction was 29%. The H-V interval was prolonged in two of seven patients. Pump failure was the acute cause of the deaths. The presence or absence of a prolonged H-V interval did not affect mortality in this group of patients.
37例急性心肌梗死合并房室或束支传导阻滞或两者皆有的患者，在冠心病监护病房住院期间进行了希氏束电图检查。14例合并束支传导阻滞患者的急性死亡率为50%。泵衰竭是主要死因。该组中有3例患者H-V间期延长，1例患者希氏束分裂。H-V间期延长与否并不影响该组患者的死亡率。16例下壁心肌梗死患者的急性死亡率为6%。除1例患者外，其余患者的H-V间期均正常。所有病例的房室传导阻滞均由近端阻滞引起。7例前壁心肌梗死患者的急性死亡率为29%。7例患者中有2例H-V间期延长。泵衰竭是急性死亡原因。H-V间期延长与否并不影响该组患者的死亡率。
