胎儿异常心电图22908例分析

Analysis of 22 908 cases abnormal electrocardiogram in fetus

探讨产前检查胎儿异常心电图的价值。方法：对孕18~42周的23 665例孕妇进行常规胎儿心电图检查,统计胎儿各类异常心电图的发生率。结果：成功检测胎儿心电图22 908例,检测成功率96.8%,胎儿异常心电图3 540例（15.5%）,按发生率高低各类心电图排名依次为胎儿心动过速（29.8%）、ST段改变（21.3%）、FQRS电压增高（19.5%）。结论：胎儿心电图检测可早期诊断胎儿心律失常,及时反映胎儿宫内缺氧情况,为孕期胎儿心律失常早治疗提供重要依据。

Objective：To explore value examining fetal abnormal electrocardiogram（ECG）in prenatal examination.Methods：A total of 23 665pregnant women in 18~42weeks underwent routine fetal ECG examination and incidence rates of various kinds of fetal abnormal ECG were counted.Results：A total of 22 908fetal ECG were successfully detected,and successful detection rate was 96.8%.There were 3 540cases of fetal abnormal ECG and its detection rate was 15.5%.Among fetal all types abnormal ECG,their ranking was fetal tachycardia（29.8%）,ST segment change（21.3%）and FQRS voltage increase（19.5%）in turn according to incidence rate degree.Conclusion：Fetal ECG detection may early diagnose fetal abnormal electrocardiogram,which can reflect intrauterine fetal anoxia;It can provide important evidence for early treatment of fetal abnormal electrocardiogram.
