Lee等认为胎心率(FHR)加速结合胎动可视为胎儿良好。其后,根据一定时期内FHR加速结合胎动的存在而进行的非应激性试验受到产科及围产科医生的普遍重视。Weingold等指出非周期性胎心率加速伴有胎动是最常见的模式,这种加速典型地在14-25次/分,并历时10-30秒。Timor-Tritsch等曾证明FHR加速似发生于胎动开始时或近于开始时。胎动与观察到的加速近于同时发生,说明此两种功能的调控可能来自胎儿大脑。Martin证明胎儿心脏交感神经支配的激活作用引起心率加快。本文研究的目的在于证实产母感到的及实时超声描记见到的胎动与FHR加速之间的相关。研究组包括28例正常低危孕妇及24例来自Ha dassah大学医院高危妊娠病房的患者。产妇皆为妊娠33-41周,无一例临产。用外部多普勒超声系
Lee and others believe that fetal heart rate (FHR) acceleration combined with fetal movement can be considered a good fetus. Subsequently, non-stress tests based on accelerated FHR combined with fetal movement over a period of time have received widespread attention from obstetric and perinatal physicians. Weingold and colleagues point out that the most common pattern of atrial fibrillation is accelerated atrial fibrillation. This acceleration is typically 14-25 beats / min and lasts for 10-30 seconds. Timor-Tritsch et al. Have demonstrated that FHR acceleration occurs at or near the beginning of fetal movement. Fetal movements and observed accelerations occurred almost simultaneously, indicating that the regulation of both functions may come from the fetal brain. Martin proves that the activation of the sympathetic innervation of the fetal heart causes an increase in heart rate. The purpose of this study was to confirm the correlation between fetal movement and fetal FHR acceleration seen in real-time sonography. The study group included 28 patients with normal low-risk pregnancies and 24 patients with high-risk pregnancy wards from Ha dassah university hospital. Maternal are pregnant for 33-41 weeks, no case of labor. External Doppler ultrasound system
