Abstract:Objective To discuss the mechanism and clinical value of short P-R interval on ECGs of pregnant women. Methods A total of 1 286 pregnant women were randomly selected from patients admitted into our hospital from January 2016 to January 2017. According to gestational weeks, they were divided into group A(422 cases, ≤13 weeks), group B(487 cases, 13<gestational weeks<28) and group C(377 cases, ≥28 weeks). Another 100 healthy non-pregnant women of the right age were taken as control group, who had undergone physical examination in our hospital during the same time period. ECG monitoring was performed on the three groups with the frequency of short P-R interval recorded, and the occurrence of sinus tachycardia and anemia was observed.Results The incidence of short P-R interval in group B and C was separately 4.52% and 7.16%, significantly higher than 1.00% in control group and 1.18% in group A, with statistically significant differences(P<0.05). The incidence of anemia in group A, B and C was separately 3.79%, 7.39% and 11.40%, all significantly higher than 0.00% in control group. The incidence of sinus tachycardia in group B and C was separately 4.11% and 7.96%,also significantly higher than 0.00% in control group and 1.66% in group A. With the increasement of gestational weeks, the incidences of anemia and sinus tachycardia also markedly elevated(P<0.05). Conclusion Compared with healthy non-pregnant check-up females of the right age, the incidence of short P-R interval significantly increased in middle and late pregnancy women. It is believed that increased gestational weeks contribute greatly to the occurrence of short P-R interval which is related to anemia and increased heart rate.
