The purpose of this study was to examine the heart rate patterns before and after a standardized external vibratory acoustic stimulation in a group of 24 healthy premature fetuses at 32-35 weeks gestational age. FHR was analysed on line by Sonicaid Computer System 8000. A significant increase in the number of accelerations and an increase of variation after stimulus were observed. All other FHR patterns such as baseline, high and low episodes did not change significantly.
本研究的目的是在一组24例孕龄为32 - 35周的健康早产胎儿中，检测标准化外部振动声刺激前后的心率模式。通过Sonicaid计算机系统8000对胎心率（FHR）进行在线分析。观察到刺激后加速次数显著增加以及变异性增加。所有其他FHR模式，如基线、高低值时段，均无显著变化。
