The initial ECG is the most rapid and readily available tool in the emergency department for the evaluation of patients presenting with suspected myocardial infarction. However, studies have shown that the initial ECG is diagnostic of acute myocardial infarction in only a minority of patients. This paper discusses the importance of the initial ECG and other information in aiding the disposition of patients with suspected myocardial infarction. Classic electrocardiographic descriptions are discussed as well as the newer terminology of Q wave versus non-Q wave infarction and ST segment versus T wave infarction. A brief review is made of the electrophysiology of the ECG changes seen in myocardial infarction. Finally, clinical studies are presented that establish a definite role for the use of the initial ECG.
初始心电图是急诊科评估疑似心肌梗死患者时最快速且易于获取的工具。然而，研究表明，仅少数患者的初始心电图可诊断急性心肌梗死。本文讨论了初始心电图及其他信息在协助处理疑似心肌梗死患者方面的重要性。文中讨论了经典的心电图描述，以及Q波梗死与非Q波梗死、ST段梗死与T波梗死的新术语。对心肌梗死时心电图变化的电生理机制进行了简要回顾。最后，介绍了确定初始心电图应用明确作用的临床研究。
