The temporal organization (nonrandomness) of fetal heart rate (FHR), fetal movement, and their association was evaluated in 20 normal pregnancies at 20 to 22 or 28 to 30 weeks of gestation with the use of external electronic fetal monitoring and statistical analysis with the runs test. At 20 to 22 weeks, significant clustering was found in one of 10 pregnancies for FHR change, two of 10 pregnancies for fetal movement, and one of 10 pregnancies for FHR changes associated with fetal movement. At 28 to 30 weeks, significant clustering was found in eight of 10 pregnancies for FHR change, eight of 10 pregnancies for fetal movement, and all 10 pregnancies of FHR change associated with fetal movement. There was significantly more clustering of FHR change, fetal movement, and FHR change associated with fetal movement at 28 to 30 weeks of gestation than at 20 to 22 weeks of gestation. Clustering of FHR changes was highly correlated with clustering of fetal movement.
在20例妊娠20至22周或28至30周的正常妊娠中，使用外部电子胎儿监护仪并通过游程检验进行统计分析，对胎儿心率（FHR）、胎动及其相关性的时间组织（非随机性）进行了评估。在20至22周时，10例妊娠中有1例FHR变化、2例胎动、1例FHR变化与胎动相关出现显著聚类。在28至30周时，10例妊娠中有8例FHR变化、8例胎动、10例FHR变化与胎动相关均出现显著聚类。与妊娠20至22周相比，妊娠28至30周时FHR变化、胎动以及FHR变化与胎动相关的聚类显著更多。FHR变化的聚类与胎动的聚类高度相关。
