目的比较初产妇和经产妇妊娠期心电图PR间期缩短的发生率并探讨妊娠期妇女PR间期缩短的发生机制和临床意义。方法选择1071例妊娠期妇女,其中初产妇647例,经产妇424例,对其晚期的心电图P-R间期缩短的发生率进行分析。结果初产妇中39例出现PR间期缩短,经产妇中26例出现PR间期缩短,且孕中晚期的发生率高于孕早期。结论妊娠期妇女出现PR间期缩短为生理性改变,与年龄和妊娠次数没有关联,产后多恢复正常。
Objective To compare the incidence of PR interval shortening between primipara and maternal gestational ECG and explore the mechanism and clinical significance of PR interval shortening in pregnant women. Methods A total of 1071 pregnant women, including 647 primiparae and 424 maternal women, were included in this study. The incidence of P-R shortening in the late electrocardiogram was analyzed. Results 39 cases of primiparaea PR interval shortened, the maternal 26 cases appeared PR interval shortened, and the incidence of early pregnancy is higher than that of early pregnancy. Conclusions Pregnancy women with PR interval shortened to physiological changes, with age and number of pregnancies no correlation, postpartum and more returned to normal.
