女性心电图T波低平或浅倒置的临床意义

Significance of global T-wave low or inversion in women

目的探讨女性心电图12导联T波普遍低平或浅倒置的临床意义。方法46例女性,年龄45～70岁,平均58.79±6.23岁,临床有阵发胸痛或无任何症状,心电图示12导联T波普遍低平或浅倒置,行冠脉造影或冠脉CT+三维成像(MSCT),观察冠脉病变与T波改变之间的关系。结果46例女性中,冠脉造影或冠脉CT+三维成像显示有7例冠脉狭窄50%～75%,占15.2%,余39例冠脉未见明显异常,占84.8%。结论中老年女性心电图12导联T波普遍低平或浅倒置不宜轻易诊为冠心病。

Objective To explore significance of global T-wave low or inversion in women. Methods Forty six women （age mean 58.79±6.23）with or without chest pain that they had global T-wave low or inversion on electrocardiogram and were performed b.y multislice computed tomography or coronary angiography for detecting atherosclerotic coronary plaques. Results There were 7 wom en （15.2%） showed significant stenosis （ ≥ 50% to75 % ） by coronary angiography or MSCT. Thirty -nine women （84.8%） had normal coronary angiogram. Conclusions Global T-wave low or inversion on electrocardiogram in middle-old-aged women do not hastily diagnosed coronary heart disease.
