摘要 目的探讨心电图在诊断急性肺栓塞中的作用。方法分析回顾12例急性肺栓塞确诊患者在溶栓前后的心电图变化。结果急性肺栓塞患者心电图变化情况:S1>0.1mV9例,QⅡTⅢ型4例,SⅠQⅡTⅢ5例,T倒置11例,Tv1-2倒置8例,Tv1-3倒置7例,Tv1-4倒置10例,Tv1-5倒置2例,T波倒置都为对称性,SV1-V5R挫折粗顿7例,不完全性右束支传导阻滞2例;进行溶栓后心电图变化情况:QⅡ消失或减少,S1变浅,QRS电轴向左移动,TⅢ倒置变浅4例,加深5例,Tv1-2直立倒置或加深6例,T波倒置直立或变浅3例,不完全性右束支传导阻滞4例,SV1-V5R粗顿、挫折消失6例;患者出院前心电图变化:TⅢ变直立8例,Tv2直立5例,RⅡ增加,RⅢ减少。结论对于急性肺栓塞来说其心电图的改变时非特异性的,在临床动态观察中如能紧密结合对于心电图的观察,不典型或所谓"大致正常"的轻微改变对急性肺栓塞的筛选是有帮助的。在进行溶栓有效治疗后,胸前导联T波倒置加深可能是右心室负荷减轻的一种表现。
