Abstract Objective To investigate the incidence of the short PR interval and relationship with the level of thyroid hormone during pregnancy. Methods From January to December 2016, in Shunyi Maternal and Children Health Care Hospital in Beijing City ("our hospital" for short), 8645 cases of pregnant women and 8650 cases of non-pregnant women from physical examination were performed an electrocardiogram as study group and control group. The pregnant women with the short PR interval were divided into three groups according to different gestational age: early pregnancy group (＜14 weeks), mid pregnancy group (14-＜28 weeks) and late pregnancy group (≥28 weeks). TSH, FT3, FT4, TT3, TT4 were tested. Results The incidence of short PR interval in pregnant women was 1.504%, and incidence of control group was 0.358%, the difference was statistically significant (P ＜ 0.01). They were statistically significant in short PR interval, TSH, FT3, FT4, TT3 and TT4 among groups (P ＜ 0.01). TSH: there was no significant difference between early pregnancy group and mid pregnancy group (P ＞ 0.05). There were significant difference between early pregnancy group and late pregnancy group, mid pregnancy group and late pregnancy group (P ＜ 0.05). Short PR interval, FT3, FT4, TT3 and TT4: there were significant difference between early pregnancy group and mid pregnancy group, early pregnancy group and late pregnancy group (P ＜ 0.01). There was significant difference between mid pregnancy group and late pregnancy group (P ＜ 0.01). Conclusion The incidence of short PR interval in pregnant women is significantly higher than that of healthy non-pregnant women. The thyroid hormone level and the short PR interval can be monitored by clinical observation. It can prevent the occurrence of arrhythmia by combining clinical symptoms effectively. It is important clinical significance to improve the safety of women with short PR interval during pregnancy.
