PR-segment depression with multilead ST-segment elevation and ST-segment depression in lead aVR are classic ECG manifestation of acute pericarditis. We present a patient, where the etiology of these ECG features was acute ST-elevation myocardial infarction due to left circumflex artery occlusion. To avoid misdiagnosis, unnecessary examinations, and inappropriate therapeutic decisions, the possibility of ST-segment elevation myocardial infarction should be kept in mind even when ECG changes typical for pericarditis are encountered in chest pain patients. Findings of QRS widening and QT interval shortening in leads with ST-segment elevation could help to differentiate acute ST-segment elevation myocardial infarction from acute pericarditis.
PR 段压低伴多导联 ST 段抬高和 aVR 导联 ST 段压低是急性心包炎的典型心电图表现。我们报告了一例患者，其心电图特征的病因是由于左回旋支闭塞导致的急性 ST 段抬高型心肌梗死。为了避免误诊、不必要的检查和不适当的治疗决策，即使在胸痛患者中遇到典型的心包炎心电图改变，也应牢记 ST 段抬高型心肌梗死的可能性。伴有 ST 段抬高的导联中 QRS 波增宽和 QT 间期缩短的发现有助于将急性 ST 段抬高型心肌梗死与急性心包炎相区分。
