摘要 目的:参照冠状动脉造影(CAG)检查结果,评价18导联心电图对ST抬高型下壁心肌梗死梗死相关动脉(IRA)判断的价值。方法:人选ST抬高型下壁心肌梗死(STEIMI)经CAG证实为冠脉闭塞的345例,人选全部左旋支闭塞组(45例)为观察组和随机右冠脉闭塞组(42例)为对照组,回顾性分析其入院时记录的18导联心电图(12导联加右胸导联和后壁导联)的细微改变推测IRA。心电图观测指标:(1)左旋支闭塞指标:STtⅡ〉Ⅲ,avL导联ST段t或无压低,sTTV7-9;(2)右冠脉闭塞指标:STtⅢ〉II、STiavL〉I、STtv导联,。结果诊断左旋支闭塞三个指标的敏感度分别是100%、87%、90%。诊断右冠脉闭塞指标的敏感度分别是64%、60%、86%。结论:18导联心电图对ST抬高型下壁心肌梗死(STEIMI)相关闭塞冠脉能提供更确切的判断。
