A statistically significant correlation exists between patterns of fetal heart rate (FHR) and neonatal state. However, the prognostic value of alterations of FHR for the individual has not been established. In 812 deliveries, we analyzed FHR tracings of the 30 minutes preceding delivery and correlated 6 characteristics of baseline, 10 of floating line and 6 of oscillation type with the incidence of severe acidosis (pH of umbilical cord artery less than or equal to 7.10) and low Apgar scores (one minute Apgar score less than or equal to 6). The exact risk for neonatal depression was calculated for each pattern of FHR. A high rate of depressed infants could be expected when the following alterations of FHR were seen during the last 30 minutes before delivery:--mild tachycardia, severe bradycardia,--severe variable decelerations, uniform late decelerations,--oscillation frequency less than 2 per minute independent of oscillation amplitude.
胎儿心率（FHR）模式与新生儿状态之间存在统计学上的显著相关性。然而，FHR变化对个体的预后价值尚未确定。在812例分娩中，我们分析了分娩前30分钟的FHR描记图，并将基线的6个特征、基线摆动的10个特征和摆动类型的6个特征与严重酸中毒（脐动脉pH值小于或等于7.10）的发生率以及低Apgar评分（1分钟Apgar评分小于或等于6）进行了关联。针对每种FHR模式计算了新生儿抑制的确切风险。当在分娩前最后30分钟出现以下FHR变化时，预计会有较高比例的新生儿抑制：轻度心动过速、严重心动过缓、严重变异减速、一致的晚期减速、每分钟振荡频率小于2次（与振荡幅度无关）。
