摘要
目的探讨妊娠期女性短PR间期的发生率,并分析其产生机制及临床意义。方法选择1491例接受常规心电图检查的女性分为两组,妊娠组1231例,健康非妊娠组260例(对照组),分析两组短PR间期的发生率。妊娠女性按年龄分为3组;按孕周分为3组,分别对各组短PR间期的发生率进行分析。结果①妊娠组心电图短PR间期102例(8.3%,102/1231),健康非妊娠组心电图短PR间期者5例(1.9%,5/260),两组比较差异有统计学意义(p<0.01);②妊娠女性在不同年龄组中短PR间期的发生率差异无统计学意义(p>0.05);③晚孕期与早孕及中孕期中短PR间期的发生率差异有统计学意义(p<0.05)。结论妊娠期短PR间期发生率较健康非妊娠期明显增高,与孕期的周数有一定相关性。
Objective To explore the incidence of short PR interval in gravid female Methods We analyzed 1491 females＇ ECG,and divided them into two groups,gravid group（1231 cases）and non-gravid group（260 cases）,then comparing and analyzing the incidence of short PR interval.And we divided the 1231 gravid cases into three age groups.And we divided 1231 gravid cases into three groups according to pregnant week.Then we respectively compared and analyzed the incidence of short PR interval.Results ① The number of short PR interval cases was 102 in the group for gravid female（8.3%,102/1231）,5 in another group for not gravid female（1.9%,5/260）.There was statistics difference for the incidence rate of short PR interval from the group for gravid female and another group for not gravid female（p〉0.01）;②There was no statistics difference for the incidence rate of short PR interval in each age group（p〉0.05）;③there was statistics difference for the incidence of short PR interval between the late and early period of pregnancy,and between the late and middle period of pregnancy（p 0.05）.Conclusions The incidence of short PR interval in the group for gravid group obviously greater than that in another group for non-gravid group;in gravid cases,the incidence rate of short PR interval had relation of pregnant week.
