[摘要] 目的 探讨妊娠期短PR间期发生率以及與甲状腺激素水平的关系。 方法 选取2016年1～12月在北京市顺义区妇幼保健院(以下简称“我院”)产检孕妇8645例为研究组，同期我院体检中心健康检查的未孕女性8650例为对照组，行心电图检查。将短PR间期孕妇分为三组：妊娠早期组( 0.05)；妊娠早期组与妊娠晚期组、妊娠中期组与妊娠晚期组比较，差异有统计学意义(P < 0.05)。各组间短PR值、FT3、FT4、TT3、TT4：妊娠早期组与妊娠中期组、妊娠晚期组比较，差异有高度统计学意义(P < 0.01)；妊娠中期组与妊娠晚期组比较，差异有高度统计学意义(P < 0.01)。 结论 妊娠期短PR间期发生率明显高于非妊娠女性。临床可通过监测甲状腺激素水平变化和短PR间期发生情况，结合临床症状，有效预防心律失常的发生，对于提高妊娠期短PR间期女性的安全性有重要的临床意义。
