A 70-year-old woman was found to have an intermittent left bundle branch block. When her electrocardiogram showed normal conduction, T-wave inversions in leads V1-V3 appeared. These alterations suggested an anteroseptal infarction. However, the patient was asymptomatic, and the serum enzymes, technetium 99m pyrophosphate scan, and the thalium 201 scan were all negative. Thus the LBBB itself can produce T-wave in versions in the right precordial leads during the normal conduction phase which may simulate an acute myocardial infarction.
一名70岁女性被发现有间歇性左束支传导阻滞。当她的心电图显示传导正常时，V1-V3导联出现T波倒置。这些改变提示前间隔梗死。然而，患者无症状，血清酶、锝99m焦磷酸盐扫描及铊201扫描均为阴性。因此，左束支传导阻滞本身在正常传导阶段可在右胸前导联产生T波倒置，这可能模拟急性心肌梗死。
