通过计算机数值分析，对 20 个生长迟缓的胎儿和 20 个与胎龄匹配的正常胎儿进行了胎心率 (FHR) 变化的研究。 14 个生长迟缓胎儿的 FHR 变异显着减少，显示出相关病理学的临床证据。通过胎心率变化和胎动的变化来评估休息活动周期。胎心率变异减少的生长迟缓胎儿表现出与正常胎儿相同的休息和活动模式，但胎心率变异的变化幅度较低。即使在胎心率变异最低的 6 个胎儿的亚组中也观察到了这一点。因此，由于胎儿活动时间较少，因此不会出现与生长迟缓相关的非反应性胎心率模式。
Fetal heart rate (FHR) variation was studied by computerized numerical analysis in 20 [human] growth-retarded fetuses and 20 normal fetuses matched for gestational age. FHR variation was significantly reduced in the 14 growth-retarded fetuses showing clinical evidence of associated pathology. Rest-activity cycles were assessed by changes in FHR variation and fetal movements. The growth-retarded fetuses with reduced FHR variation showed the same pattern of rest and activity as normal fetuses, but the changes in FHR variation were of lower amplitude. This was observed even in the subgroup of 6 fetuses with the lowest FHR variation. Thus the unreactive FHR patterns associated with growth retardation do not arise because the fetus spends less time in activity.
