急性下壁心肌梗死(IAMI)患者约50%伴有明显的心律失常和低血压,右冠状动脉的完全闭塞是其主要的病理基础,因此,早期识别IAMI的梗死相关动脉(IRA)及其闭塞部位对评估其预后以及是否需要尽快采取血管重建治疗有重要的临床意义。然而,使用最简便的心电图能否做出IRA及其闭塞部位的判断一直是近年探索的问题。本文回 Approximately 50% of patients with acute inferior myocardial infarction (IAMI) have significant arrhythmia and hypotension, and complete occlusion of the right coronary artery is the major pathological basis. Therefore, early identification of infarct-related artery (IRA) and occlusion of IAMI Location of the assessment of its prognosis and the need for revascularization as soon as possible has important clinical significance. However, the use of the most simple ECG can make IRA and determine the occlusion site has been explored in recent years. This article back
