Continuous electronic fetal heart rate (FHR) monitoring during labor is motivated by the clinical experience that fetal distress causes loss of FHR variation and the occurrence of decelerations late during uterine contraction. This practice is of uncertain clinical benefit, perhaps because the interpretation is qualitative. We have developed new quantitative measures and analyzed cardiotocograph records from 148 consecutive patients, 44 of whom had at least one "nonreassuring" epoch. In multivariate regression models, measures of deceleration and variability were significantly associated with the obstetrician's diagnosis (receiver operating characteristic area 0.84, p < 0.05). This approach may be useful clinically.
产时持续电子胎心监护（FHR）是基于临床经验开展的，即胎儿窘迫会导致FHR变异消失以及宫缩晚期减速的出现。这种做法的临床益处尚不确定，可能是因为解读是定性的。我们开发了新的定量指标，并分析了148例连续患者的胎心监护记录，其中44例至少有一个“非 reassuring”时段。在多变量回归模型中，减速和变异指标与产科医生的诊断显著相关（受试者工作特征曲线下面积为0.84，p<0.05）。这种方法在临床上可能有用。
