中晚期妊娠妇女心电图短P-R间期分析

目的:探讨妊娠期妇女心电图短P-R间期的发生率和转归。方法:测量健康体检女性(对照组)、早期妊娠妇女和中晚期妊娠妇女各400例心电图PR间期,比较各组PR间期缩短的发生率,对PR间期缩短者随访产后3个月时的PR间期变化。结果:中晚期妊娠组短P-R间期29例(7.25%),发生率高于早期妊娠组的1.5%和对照组的1.75%,中晚期妊娠组发生短P-R间期者产后3个月时28例恢复正常。结论:中晚期妊娠妇女心电图P-R间期缩短有一高发生率,但分娩后常恢复正常,可能与妊娠导致的自主神经功能改变有关。

Objective：To investgate the incidence and turnover of short P-R interval of conventional electrocardiogram during and after pregnancy period.Methods：We surveyed the P-R interval on ECG in 400 healthy people（control group） ,400 women in pregnancy early period,400 women in middle and late period.The incidence of short P-R interval was compared among these 3 groups.And the P-R interval was followed up to three months post partum in women with short P-R interval.Results：There were 29（7.25%） mid and late stage pregnancy women who got short P-R interval.The incidence rate was obviously higher than that in early stage（1.5%） pregnancy women and healthy women（1.75%） .The P-R interval in 28 late stage pregnancy women who had short P-R interval turn to normal at three months post partum.Conclusion：The short P-R interval occured in some middle and late period pregnancy women and usually turn to nomal post partum.This occurrence may related to maladjustment of autonomic nerve function.
