Blood flow velocity waveforms recorded in the fetal ductus arteriosus were related to fetal heart rate pattern (FHRP) in 13 normal pregnancies at 27-29 weeks of gestation. Recording time was always 65 min or more. In three women no low fetal heart rate (FHRP-A) variability was present, in the remaining 10 women high fetal heart rate (FHRP-B) variability was established in 80% of the recording time. There was no statistically significant difference between FHRP-A and FHRP-B pattern for all ductal flow velocity parameters, indicating rest-activity state independency in late second and early third trimester pregnancy.
对13例妊娠27至29周的正常孕妇，记录其胎儿动脉导管的血流速度波形，并与胎儿心率模式（FHRP）相关联。记录时间均为65分钟或更长。3名孕妇不存在低胎儿心率（FHRP-A）变异性，其余10名孕妇在80%的记录时间内呈现高胎儿心率（FHRP-B）变异性。所有导管血流速度参数在FHRP-A和FHRP-B模式之间均无统计学显著差异，表明妊娠中期晚期和妊娠晚期早期的静息-活动状态无关。
