摘要 目的探讨急性心肌梗死对心电图对应导联ST段压低的临床诊断意义。方法 2008年5月~2010年5月,诊断为急性心肌梗死患者中,心电图检查出现ST抬高并出现对应导联ST段压低者42例,对其进行行冠脉造影检查和心电图检查,并对检查结果进行探讨并总结。结果在对应导联ST段压低的42例急性心肌梗死患者中,其中心电图显示下壁心肌梗死25例,占59.5%;前壁心肌梗死17例,占40.5%。25例下壁心肌梗死患者的冠脉造影检查结果:右冠状动脉闭塞22例,左旋支闭塞3例,左前降支狭窄30%~75%者21例,非梗死区血管狭窄的发生率84%;17例前壁心肌梗死患者的冠状动脉造影检查结果前降支闭塞:15例,右冠状动脉狭窄者>50%者10例,左旋支狭窄>50%者3例,非梗死区血管狭窄的发生率76%。结论临床工作中应结合患者心电图、心肌酶、心脏超声等各项指标来综合判断患者病情轻重程度,并指导下一步的治疗计划。
