With several myocardial infarction (MI) registries reporting a decline in the incidence of ST-elevation MI (STEMI) and an increase in non-ST-elevation MI (NSTEMI) and unstable angina (UA), it is important that future healthcare resources are directed towards this increased volume of patients, ECG technology, core to the early diagnosis of these patients, has lagged behind relative to other techniques and little progress has been as far as acute coronary syndrome triage is concerned beyond ST-segment deviation. We present a review of the literature on current electrocardiographic changes which will allow admitting physicians to better risk stratify those patients with "non-diagnostic ECGs." These ECGs may become diagnostic with careful evaluation, use of serial ECGs and when additional lead sets are used.
随着多个心肌梗死（MI）登记处报告ST段抬高型心肌梗死（STEMI）发病率下降，非ST段抬高型心肌梗死（NSTEMI）和不稳定型心绞痛（UA）发病率上升，未来的医疗资源应针对这类患者数量的增加进行分配，这一点很重要。心电图技术是这些患者早期诊断的核心，但相对于其他技术而言，它已经滞后，就急性冠状动脉综合征分诊而言，除了ST段偏移外几乎没有进展。我们对有关当前心电图变化的文献进行了综述，这将使接诊医生能够更好地对那些“心电图无诊断意义”的患者进行风险分层。通过仔细评估、使用系列心电图以及使用额外导联组，这些心电图可能会变得具有诊断意义。
