本院于1980年起,开展经孕妇腹壁测胎儿心电图(FECG)。三年来,对222例孕妇共测FECG800例次,成功742例次,占92.88％最早是在孕期第12周测得,测出的心电图图形有母亲及胎儿两种。FECG电压较小,频率较快,每分钟为132～163次左右。孕33周以前胎心率较快,37周后较慢。P、T波不明显,QRS综合波时限为0.03～0.06秒。共发现异常FECG19例。其中提示心室内及(或)完全性房室传导阻滞1例,早搏14例,明显心律不齐2例,QRS综合波时限增宽2例。除2例来在我院分娩失随访外,17例均测新生儿ECG作对照。FECG对母儿无损伤,可反复测定,侧出成功率较高,可作为孕期监护方法之一。
The hospital in 1980, carried out by pregnant women abdominal wall test fetal electrocardiogram (FECG). Three years, a total of 222 cases of pregnant women were tested FECG800 cases, 742 cases of successful, accounting for 92.88% was first measured during the twelfth week of pregnancy, the measured electrocardiogram with both mother and fetus. FECG voltage smaller, faster frequency of 132 to 163 times per minute or so. Fetal heart rate faster than 33 weeks before pregnancy, 37 weeks later. P, T wave is not obvious, QRS comprehensive wave time limit of 0.03 ~ 0.06 seconds. A total of 19 cases of abnormal FECG were found. Which prompted intraventricular and (or) complete atrioventricular block in 1 case, premature beat in 14 cases, 2 cases of significant arrhythmia, QRS comprehensive wave of two patients widened. In addition to two cases of loss of childbirth in our hospital, 17 neonates were measured as a control. FECG on the mother and child without injury, can be repeatedly measured, a high success rate, can be used as one of the methods of pregnancy monitoring.
