Methods Fetal movement, fetal heart rate, ultrasonography, umbilical artery flow velocity were examined in638 cases of pregnant women before delivery. 方法对638例孕妇产前常规进行胎动、胎心率电子监护、超声显像与多普勒脐动脉血流速度检查。
Objective To investigate the relationship between V variable deceleration in non-stress test of fetal heart rate and abnormal amniotic fluid and umbilical cord and pregnancy outcome. 目的探讨无负荷试验中V型减速与脐带、羊水异常及围生儿结局的关系。
OBJECTIVE To study the role of fetal heart rate monitoring and color Doppler ultrasonography examination in fetal distress prognosis. 目的探讨临产前电子胎心监护联合彩超判断胎儿预后的价值。
One of the main methods of fetal monitoring is monitoring the fetal heart rate ( FHR ), and the method based on Ultrasonic Doppler Effect is a effective method without wound to detect the FHR. 监听胎儿心率(FHR)是胎儿监护的主要方法之一,基于超声多普勒效应的胎心率检测法是一种有效的无创方法。
