摘要
对69例急性下壁（右室、后壁）心肌梗死患者心电图改变与冠状动脉造影资料进行对比分析。结果示ST段抬高Ⅲ〉Ⅱ判断右冠状动脉（RCA）为梗死相关动脉（IRA）的敏感性和特异性分别为92．00％、84．21％，ST段压低avL〉Ⅰ判断RCA为IRA的敏感性和特异性分别为90．00％、89．47％。显示急性下壁心肌梗死sT段抬高RI〉Ⅱ、ST段压低avL〉Ⅰ和V1、V2导联ST段无压低高度提示RCA为IRA；反之，提示左回旋支为IRA。
The results of electrocardiogram and coronary angiography were compared in 69 patients with acute inferior myocardial infarction （right ventricle, later wall）. The sensitivity and specificity of ST segment elevation Ⅲ〉 Ⅱ in diagnosis of right coronary artery （RCA） as the infarction related artery （IRA） were 92. 00% and 84. 21% respectively; those for ST segment depression avL 〉 Ⅰ were 90. 00% and 89. 5% respectively. Therefore if ST-elevation Ⅲ 〉 Ⅲ , ST-depression avL 〉 Ⅰ and no depression on STV1 and V2 in acute inferior myocardial infarction may highly indicate that RAC be the IRA; on the contrary, the LCX be the IRA.
