Twenty pregnant women between 30 and 32 weeks' gestational age were studied to examine the effects of a 5-second external vibratory acoustic stimulus on the fetal heart rate, fetal heart rate variability, and fetal activity patterns. There was an immediate significant increase in the basal fetal heart rate for 10 minutes compared with controls. There was also a significant increase in the mean duration of fetal heart rate accelerations without any change in the number of fetal heart rate accelerations. There were no changes in long-term fetal heart rate variability, fetal breathing, and gross fetal body movements.
对20名孕龄在30至32周的孕妇进行了研究，以检验5秒外部振动声刺激对胎儿心率、胎儿心率变异性和胎儿活动模式的影响。与对照组相比，基础胎儿心率在10分钟内立即显著增加。胎儿心率加速的平均持续时间也显著增加，而胎儿心率加速的次数没有变化。长期胎儿心率变异性、胎儿呼吸和胎儿整体身体运动均无变化。
