Abstract：Objective To investigate the characteristics and relationship of the incidence, mechanism and the level of thyroid hormone in the short PR interval during pregnancy. Methods the Jinke ECG network information system workstation to 40301 healthy non pregnant controls and p8257 cases of healthy pregnant women were routine ECG examination and by chemical luminescent immunoassay method and reagent of form a complete set to determine the free three iodine thyroid original ammonia acid (FT3) during pregnancy and free iodine thyroid original ammonia acid (FT4), thyrotropin (TSH). The pregnant women were divided into groups according to different gestational age (12 weeks), the middle gestational period (13-28 weeks), three weeks after the second trimester (29 weeks), and the data of, FT4, TSH, FT3, and PR were collected, and the results were statistically analyzed. Results 120 patients (0.3%) had 79 cases (0.196%), 41 cases (0.102%), 111 cases (1.344%), and two two cases, the incidence rate was significantly higher, the difference was statistically significant (P<0.01). FT3, FT4 increased with the increase of gestational age, FT4 in the two two groups, the difference was statistically significant (P<0.05), TSH increased with the increase of the gestational age, the difference was not statistically significant (P>0.05, P=0.67), and the difference between early and late pregnancy was statistically significant (P<0.05). Conclusion the incidence of short PR interval in pregnant women was significantly higher than that of healthy non pregnant women.
