本文研究了43例孕26 ~ 40周的健康孕妇，在体外振动声刺激后，刺激前基础心率对第一胎心率加速度最大幅度的影响。从30周到足月，第一胎心率加速度的最大幅度与刺激前基础胎心率呈显著负相关。在存在胎儿心动过速（基础胎心率> 160次/min）的情况下，刺激后超过50%的胎心率加速度小于15次/min幅度。在26 ~ 28周和30 ~ 32周之间，胎儿对振动声刺激的即刻胎心率反应也有一个显著的成熟过程，其特征是基础胎心率延长增加，刺激后第一次加速度的最大幅度增加。
Forty-three healthy pregnant women between 26 and 40 weeks'' gestation were studied to determine the influence of prestimulation basal heart rate on the maximum amplitude of the first fetal heart rate acceleration after external vibratory acoustic stimulation. A significant negative correlation was found between the maximum amplitude of the first fetal heart rate acceleration and the prestimulation basal fetal heart rate from 30 weeks to term. In the presence of fetal tachycardia (basal fetal heart rate > 160 beats/min), more than 50% of fetal heart rate accelerations after stimulus were less than 15 beats/min amplitude. There was also a significant maturational process in the immediate fetal heart rate response to vibratory acoustic stimulation that occurred between 26 to 28 and 30 to 32 weeks characterized by a prolonged increase in basal fetal heart rate and an increase in the maximum amplitude of the first acceleration after stimulation.
