高龄孕妇妊娠晚期心电图与妊娠结局的关系

The relationship of ECG and pregnancy outcome of older pregnant woman in late pregnancy

目的:观察妊娠晚期孕妇的异常心电图变化和妊娠结局。方法:妊娠晚期孕妇按年龄分为35岁以上组和35岁以下组,行心电图检查,统计各型异常心电图发生率,记录妊娠、分娩结局及是否出生低体重儿。结果:妊娠晚期35岁以上组孕妇异常心电图发生率显著高于35岁以下组(P<0.05);其中,ST段改变、心律失常发生率前者显著高于后者(P<0.05);各型心律失常中,前者窦性心动过缓、室性早搏的发生率显著高于后者(P<0.05),而窦性心动过速的发生率明显低于后者(P<0.05)。心电图异常者35岁以上组妊娠丢失率明显高于35岁以下心电图正常和异常组(P<0.05);35岁以上孕妇心电图异常组早产发生率高于心电图正常组(P<0.05);心电图异常35岁以上组新生儿低体重发生率显著高于心电图正常35岁以下组(P<0.05)。结论:高龄孕妇妊娠晚期易发生心律失常、心肌缺血等异常心电图,异常心电图高龄孕妇易发生妊娠丢失、早产及分娩低体重婴儿。

Objective： To observe the changes of electrocardiogram（ ECG） and pregnancy outcome of the late pregnancy women. Meth- （Ms： Late pregnancy women were divided into two groups by age： over 35 group and under 35 group. The incidence of abnormal electrocardio- gram was recorded when the patients were subjected to routine ECG examination. Then the pregnancy, delivery outcome and if there＇s low birth weight newborn were recorded later. Results： The incidence of abnormal ECG in over 35 group was significantly higher than that in under 35 group（ P 〈0.05）. And the incidence of ST se^nent changes, arrhythmia in the group of former was higher than that in the group of latter （ P 〈 0.05）. Among the different type of arrhythmia, the incidence of sinus bradycardia and ventricular premature beat in the group of former were higher than those in the group of latter（ P 〈 0.05）. But the incidence of sinus tachycardia in the former group was obviously lower than that in the latter group（ P 〈0.05）.The incidence of pregnancy loss in over 35 with abnormal ECG group was significantly higher than that in under 35 with normal or abnormal ECG groups（ P 〈 0.05）. The incidence of premature birth in over 35 with abnormal ECG group was signifi- cantly higher than that in over 35 with normal ECG group（ P 〈 0.05）. The incidence of low body weight in over 35 with abnormal ECG group was significantly higher than that in under 35 with normal ECG group（ P 〈0.05）. Conclusion： The late pregnancy women with the age of over 35 are more likely to have ECG abnormalities, such as arrhythmia, myocardial ischemia and so on. The older pregnant women with abnormal ECG easily suffer from pregnancy losing, premature birth and having a low birth weight baby.
