Complete left bundle branch block often masks old as well as acute myocardial infarctions. However, a diagnosis of acute myocardial infarction in the presence of complete left bundle branch block can be made when the acute injury current is large enough to modify the secondary repolarization abnormalities of left bundle branch block. Under these circumstances the classical ST-T changes of an acute infarction may evolve in serial electrocardiograms.
完全性左束支传导阻滞常掩盖陈旧性及急性心肌梗死。然而，当急性损伤电流足够大，足以改变左束支传导阻滞的继发性复极异常时，可在完全性左束支传导阻滞的情况下作出急性心肌梗死的诊断。在这种情况下，急性梗死典型的ST-T改变可能会在系列心电图中演变。
