本文应用ＦＥＣＧ－Ｄ型仪对４００例围产胎儿进行了ＦＥＣＧ的检测及分析。结果成功３６３例，成功率为９０．８％，正常ＦＥＣＧ３１６例占成功数的８７％，异常ＦＥＣＧ４７例占成功数的１３％。在对异常ＦＥＣＧ的类型及原因的分析中发现，异常ＦＥＣＧ中以ＦＳＴ下移＞５ｕｖ为多占５３．２％，其次为胎儿心动过速２５．６％，胎儿心动过缓１０．６％。胎儿心律不齐６．３％，ＦＱＲＳ时限增宽４．３％。胎儿心电图异常的原因为胎儿窘迫占７８．７％，脐带绕颈１２．８％，提示胎儿宫内缺氧是引起围产ＦＥＣＧ异常的主要原因，２２例（４７％）异常ＦＥＣＧ分别经胎盘给药、吸氧、输液等处理转为正常。
In this paper, FECG-D type instrument on 400 cases of fetus FECG detection and analysis. The results were successful in 363 cases, the success rate was 90.8%, normal FECG316 cases accounted for 87% of the successful, 47 cases of abnormal FECG accounted for 13% of the successful number. In the analysis of the types and causes of abnormal FECG, it was found that in the abnormal FECG, more than 5uv was taken down by FST for 53.2%, followed by 25.6% of fetal tachycardia and 10.6% of fetal heartbeat. Fetal arrhythmia 6.3%, FQRS widening of 4.3%. Fetal ECG abnormalities due to fetal distress accounted for 78.7%, umbilical cord around the neck 12.8%, suggesting that intrauterine hypoxia is the main cause of perinatal FECG abnormalities, 22 cases (47%) abnormal FECG were placental Medicine, oxygen, infusion and other treatment turned normal.
