The morphology of ventricular premature complexes (VPCs) is useful in detecting old or recent myocardial infarction. Rarely, however, have VPCs provided the first objective evidence of transmural myocardial infarction. In two patients with chest pain, VPCs early in the hospital course revealed myocardial infarction, while normally conducted sinus beats showed no evidence of acute transmural infarction. Transmural infarction with total occlusion of a large coronary artery was confirmed angiographically. We conclude that acute transmural myocardial infarction may be diagnosed early and accurately from VPC morphology before the appearance of other evidence of infarction.
室性早搏（VPCs）的形态有助于检测陈旧性或近期心肌梗死。然而，VPCs很少能提供透壁性心肌梗死的首个客观证据。在两名胸痛患者中，住院早期的VPCs显示出心肌梗死，而正常传导的窦性搏动未显示急性透壁性梗死的证据。冠状动脉造影证实了大冠状动脉完全闭塞的透壁性梗死。我们得出结论，在出现其他梗死证据之前，可根据VPC形态早期准确诊断急性透壁性心肌梗死。
