目的:分析不同程度妊高征的心电图表现,探讨心电图变化与不同程度妊高征之间关系。方法:收集晚期孕检或分娩患者中125例妊高征,分为轻、中、重3组,按常规方法描记分析心电图,另抽取125例正常晚孕期孕妇心电图作为对照组。结果:125例妊高征中,78例心电图异常,占62.4%。其中轻度妊高征心电图异常10.4%;中度妊高征心电图异常为20.0%;重度妊高征心电图异常为32.0%。对照组的心电图异常为12例,占9.6%。妊高征心电图异常组与正常晚孕期心电图异常组相比有明显统计学意义(P<0.01)。结论:妊高征患者中异常心电图的构成比明显高于正常妊娠组,随着病情程度加重而心电图异常明显提高。妊高征心电图异常主要为窦速、短P-R间期等改变。心电图在一定程度上可以预测妊高征严重程度存在。
Objective: To analyze the ECG manifestations of different degrees of PIH and to explore the relationship between ECG changes and PIH. Methods: 125 cases of pregnancy induced hypertension (PIH) were collected from late pregnancy test or childbirth. The patients were divided into three groups: light, medium and heavy. Electrocardiogram (ECG) was performed according to the conventional method. Another 125 pregnant women with normal pregnancy were selected as the control group. Results: Among 125 cases of PIH, 78 cases had abnormal electrocardiogram (62.4%). Incidence of mild PIH electrocardiogram abnormal 10.4%; moderate PIH abnormal ECG was 20.0%; severe PIH abnormal ECG was 32.0%. The control group of ECG abnormalities in 12 cases, accounting for 9.6%. The PIH abnormal ECG group was significantly different from the normal ECG in the late pregnancy (P <0.01). Conclusion: The proportion of abnormal electrocardiogram in patients with PIH is significantly higher than that of normal pregnancy group. As the severity of the disease aggravates, the ECG abnormalities increase significantly. PIH ECG abnormalities mainly sinus speed, short P-R interval and other changes. To some extent, ECG can predict the severity of PIH exist.
