摘要 目的探讨心电图检查在急性肺栓塞诊疗中的临床意义。方法回顾性分析28例确诊的急性肺栓塞患者入院时及溶栓后1周心电图的变化。结果(1)急性肺栓塞患者入院时心电图的改变:SⅠ>0.1mV者15例次(53.57%),SⅠQⅢTⅢ型10例次(35.71%),QⅢTⅢ型3例次(10.71%),TⅢ倒置16例次(57.14%),TV1-V2倒置15例次(53.57%),TV1-V3倒置11例次(39.29%),TV1-V4倒置8例次(28.57%),TV1-V5倒置3例次(10.71%),T波倒置均呈对称性,完全/不完全性右束支传导阻滞5例次;(2)溶栓后1周心电图的变化:SⅠ变浅,QRS电轴左移,QⅢ减少或消失;TV1-V2倒置加深或直立变倒置7例,电轴右偏和完全/不完全性右束支传导阻滞消失3例次;窦性心动过速、SⅠQⅢTⅢ型、顺钟向转位、avR终末R波等指标阳性率有所减少,差异有显著性(P<0.05)。结论急性肺栓塞患者心电图的改变是非特异性的,动态观察心电图典型、不典型轻微改变对筛选急性肺栓塞有一定的帮助。有效溶栓治疗后,胸前导联T波倒置加深可能是右室负荷减轻的一种表现。
