【摘要】 本文总结了>36孕周高危妊娠的胎儿心电图(FECG)共30例。同时分别作NST和B超监测,并以上述两项结果作对照。经过分析认为:FECG是反映胎儿在于宫内是否正常的一种客观检查指标。异常FECG提示胎儿宫內缺氧,FQRS>0.05秒或FST段改变时要注意脐带绕颈和羊水过少;而FQRS振幅>30μV时要注意羊水过少或胎儿体重≥3500g,并认为FQRS>0.05秒,振幅>30μV及FST段改变,可作为异常FECG的重要指标。其检出胎儿异常率和敏感性与NST和B超比较有显著差异(P<0.01)。更多还原

【Abstract】 We have summed up 30 cases of fetal ECG of high risk pregnancies which were over 36 weeks of pregnancy and detected NST and B-Ultrasound respectively at the same time. The results have been compared and analysed. Our conclusion is that the fetal ECG is an objective index which can reflect whether the fetus in the uterus is normal or not. Abnormal fetal CG suggests that the fetus is hypoxic. If there is change of FST or FQRS is over 0.05 second, there may be cord around neck or oligoamnios; If the amplitude of FQRS is over 30uv, there may be oligoamnios or the fetus is 3500g or over. That the FQRS is 0.05 second or over, its amplitude is over 30uv and there is change of FST is an important index of abnormal FECG. The difference of sensitivities of detecting abnormal fetus rate among this method, NST and B-Ultrasound is obvious (P<0.01)更多还原
