急性心肌梗死对应导联ST段下移的研究进展

The Research Development of Reciprocal ST Segment Depression in Acute Myocardial Infarction

急性心肌梗死患者心电图可出现ST段抬高 ,而在这些ST段抬高的患者中可同时出现梗死对应导联ST段下移。国内外进行了大量的临床和基础研究 ,认为对应导联ST段下移有助于急性心肌梗死的早期诊断 ,帮助判断冠状动脉阻塞位点和分析危险程度 ;镜象变化、远端缺血是其产生的主要原因。本文对急性心肌梗死对应导联ST段下移的临床意义及发生机制进行综述。

ST segment elevation may occur in the acute myocardial infarction patients,among whom occasionally with reciprocal ST segment depression.Lots of clinical and basic studies have been done both in home and abroad,which suggested that reciprocal ST segment depression facilitates earlier diagnosis,detects the site of occlusion and the degree of danger; mirror change and distal ischemia are the main cause.This article reviews the clinical significance and forming mechanism of reciprocal ST segment depression.
