胎儿心电图125例中异常心电的特点与临床表现

The characteristics and clinical manifestations of abnormal fetal electrocardiogram in 125 cases

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%。(3)6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。

Objective To diagnosis of fetal arrhythmia by fetal electrocardiogram（FECG）and analyze the possible causes of fetal arrhythmia.Methods The data of 125 cases 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（1）There was 40 cases（32%）with fetal abnormal electrocardiogram（ECG）.Among them,there were 30 cases（24%）with atrial premature beats,3 cases（2.4%）with fetal ventricular premature beats;3 cases（2.4%）with fetal bradycardia;3 cases with fetal tachycardia：2 cases（1.6%）with fetal atrial flutter and 1 cases（0.8%）with fetal atrial arrhythmia tachycardia.（2）In 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.（3）Six cases of termination the pregnancy and 1 cases of stillbirth.Conclusion The FECG can quickly and accurately diagnose arrhythmia and provide reference for clinical management.
