External monitorings of fetal heart rate in 2,628 cases of cord around the neck and funis presentation from June 1985 to June 1991 were analysed. The positive rate was 81.66% and the pseudo-negative rate 18.34%. 1,680 cases (63.93%) with variable deceleration were observed. Among them V wave was seen in 745 monitorings (28.53%), mostly due to umbilical compression: U wave in 238 monitorings (9.06%), mostly due to intrauterine asphyxia; and W wave in 223 monitorings (8.49%), more due to cord compression and funis presentation but also due to acute fetal intrauterine anoxia, rebound acceleration and rebound deceleration wave was observed in 316 monitorings (12.02%), more due to cord compression. The remaining 158 monitorings (6.01%) showed mixed waves. There were 51 perinatal deaths including 6 fetal, 5 still births, and 40 neonatal deaths. The perinatal mortality rate was 19.41%. The relationship among the monitor waves, the fetal growth, umbilical cord, nature of the amnionic fluid, Apgar score, etc, immediately after delivery was analyzed and the clinical significance was discussed. It was suggested that Nipple Stimulation Contraction Stress Test (NS-CST) or Contraction Stress Test (CST) could be used as a good method for prenatal diagnosis.
对1985年6月至1991年6月期间2628例脐带绕颈及脐带先露病例的胎儿心率进行了外部监测分析。阳性率为81.66%，假阴性率为18.34%。观察到1680例（63.93%）出现变异减速。其中，745次监测（28.53%）出现V波，主要由于脐带受压；238次监测（9.06%）出现U波，主要由于宫内窒息；223次监测（8.49%）出现W波，更多是由于脐带受压和脐带先露，但也由于急性胎儿宫内缺氧，316次监测（12.02%）出现反弹加速和反弹减速波，更多是由于脐带受压。其余158次监测（6.01%）显示混合波。围产期死亡51例，其中死胎6例，死产5例，新生儿死亡40例。围产儿死亡率为19.41%。分析了分娩后即刻监测波与胎儿生长、脐带、羊水性质、阿氏评分等之间的关系，并探讨了其临床意义。建议乳头刺激宫缩应激试验（NS-CST）或宫缩应激试验（CST）可作为产前诊断的良好方法。
