胎儿心电图125例中异常心电的特点与临床表现

摘要

Objective To diagnosis of fetal arrhythmia by fetal electrocardiogram(FECG)and analyze the possible causes of fetal arrhythmia. Methods The data of 125cases of pregnant women receiving FECG check due to abnormal prenatal examination were retrospectively analyzed.Meanwhile,echocardiography and clinical data of these cases were also taken into consideration. Results ①There was 40cases(32％)with fetal abnormal electrocardiogram (ECG).Among them,there were 30cases(24％)with atrial premature beats,3cases(2.4％)with fetal ventricular premature beats;3cases(2.4％)with fetal bradycardia;3cases with fetal tachycardia:2cases(1.6％) with fetal atrial flutter and 1cases(0.8％)with fetal atrial arrhythmia tachycardia.②In our study,the general causes of fetal arrhythmia were acute respiratory infection of pregnant women,abnormal fetal structure and maternal antinuclear antibody positive,which accounted for 72.5％,12.25％and 10％,respectively.③Six cases of termination the pregnancy and 1cases of stillbirth. Conclusion The FECG can quickly and accurately diagnose arrhythmia and provide reference for clinical management.%目的 应用胎儿心电图(FECG)诊断胎儿心律失常,分析心律异常的可能原因.方法 回顾本院125例因产前检查异常行FECG检查的病例,结合心脏超声和临床资料分析胎儿心律失常的特点、病因及转归.结果 ①胎儿异常心电图40例(32％),其中房性早搏30例(24％);室性早搏3例(2.4％);胎儿心动过缓3例(2.4％);心动过速3例:心房扑动2例(1.6％)和紊乱性房性心律1例(0.8％).②一般原因为孕妇急性呼吸道感染,胎儿结构异常,母体抗核抗体阳性为主,分别占72.5％ 、12.25％和10％.③6例终止妊娠,1例死胎.结论 FECG能快速、准确诊断心律失常,为临床管理提供参考依据.
