摘　　要：目的分析研究妊娠期妇女心电图短P-R间期的发生机制及临床价值。方法选取本院2016年3月—2018年9月期间接受检查的97名育龄妇女进行此次研究,所有育龄妇女分别在孕前、妊娠早期、妊娠中期以及妊娠晚期各进行一次心电图检查,对P-R间期演变进行对比分析。结果妊娠晚期P-R间期缩短发生率高于妊娠中期,差异有统计学意义(P<0.05),妊娠中期P-R间期缩短发生率高于妊娠早期及孕前,差异有统计学意义(P<0.05)。结论妊娠期妇女孕周越长,其心电图出现短P-R间期的概率越大,在该方面的研究值得进一步加强。Objective To analyze the mechanism and clinical value of short P-R interval in electrocardiogram in pregnant women.Methods A total of 97 women of childbearing age who were examined during the period from March 2016 to September 2018 were enrolled in the study.All women of childbearing age underwent an electrocardiogram examination before pregnancy,early pregnancy,mid-pregnancy and late pregnancy.The evolution of the period is comparatively analyzed.Results The incidence of PR interval shortening in late pregnancy was significantly higher than that in the second trimester.The difference was statistically significant(P<0.05).The incidence of PR interval shortening in the second trimester was significantly higher than that in early pregnancy and before pregnancy.The difference was statistically significant(P<0.05).Conclusion The longer the gestational age of pregnant women,the greater the probability that the electrocardiogram will have a short P-R interval.The research in this aspect is worth further strengthening.
