The first 30 minutes and the last 30 minutes of 1,996 intrapartum FHR tracings were analyzed for baseline FHR, variability (amplitude and frequency of oscillations), accelerations, and decelerations. A modified FHR scoring system incorporating these FHR features was employed. According to the association between various FHR scores and the incidence of low Apgar scores, FHR patterns were grouped into three basic categories with distinct prognostic significance: (1) normal FHR patterns, (2) compensated distress patterns, and (3) decompensated distress patterns. It is concluded that the prognostic significance of FHR tracings is increased by incorporating several FHR monitoring criteria in the analysis.
对1996份产时胎儿心率（FHR）监测记录的前30分钟和后30分钟进行分析，以评估基线FHR、变异性（振荡的幅度和频率）、加速和减速情况。采用了一种纳入这些FHR特征的改良FHR评分系统。根据各种FHR评分与低Apgar评分发生率之间的关联，FHR模式被分为具有不同预后意义的三个基本类别：（1）正常FHR模式，（2）代偿性窘迫模式，（3）失代偿性窘迫模式。得出的结论是，在分析中纳入多个FHR监测标准可提高FHR监测记录的预后意义。
