<Objective> The aim of this study was to investigate the effect of different emotional states during mental stress vs. relaxation on autonomic nervous activity in women and fetuses in late pregnancy by using spectrum heart rate variability (HRV) analysis.<Methods> Thirty-two pregnant women at 32 to 41 gestational weeks (mean age : 31.4 years, SD : 6.7 years) and 22 fetuses were studied. The mental stress method used was the Stroop Color Words Conflict Test (CWT), and the relaxation method used was guided imagery (GI). After 20 minutes of bed rest, maternal ECG and fetal heart rate (FHR) were recorded during the 3 states (Rest, CWT and GI) for 3 minutes. In pregnant women, data analysis of HRV in both time and frequency domains was performed, and the frequency domain shared of low frequency (LF : 0.04-0.15Hz) and high frequency (HF : 0.15-0.40Hz). The normalized HF power (high-frequency power/total power) was used as an index of modulation of vagal activity, and the LF/HF ratio was used … More as the index of modulation of sympathetic activity. At the same time STAI (State Trait Anxiety Inventory) Form-X state was measured just after the end of the states. In fetuses, data analysis of FHR in time domain and Doppler-detected fetal movement was performed.<Results> 1) In pregnant women, STAI was significantly higher in CWT than at Rest and was significantly lower in GI than CWT (p<0.001). 2) For women in late pregnancy, HF was significantly lower in CWT than at Rest (p<0.01) and was significantly higher in GI than CWT (p<0.001), and LF/HF was significantly higher in CWT than at Rest (p<0.01) and was significantly lower in GI ・han CWT (p<0.01). 3) In active phase, basal FHR was significantly lower in GI than CWT and at Rest (p<0.05), and both SD (Standard Deviation) of FHR and CV (coefficient of variance) of FHR were significantly higher in GI than CWT and at Rest (p<0.05).<Conclusion> These results suggest that emotional changes in late pregnant women affect autonomic nervous activity and that maternal emotions might have an influence on fetal reactions.

<Objective>本研究采用心率变异性（HRV）频谱分析方法，探讨孕晚期妇女和胎儿在精神紧张和放松时不同情绪状态对自主神经活动的影响。<Methods>32例妊娠32 ~ 41周的孕妇（平均年龄：31.4岁，SD：6.7岁）和22例胎儿进行了研究。心理应激方法采用Stroop色词冲突测验（CWT），放松方法采用引导想象（GI）。卧床休息20 min后，分别在静息、CWT和GI 3种状态下记录3 min的孕妇ECG和胎心率（FHR）。对孕妇的心率变异性进行了时域和频域分析，频域分为低频（LF：0.04-0.15Hz）和高频（HF：0.15-0.40Hz）。标准化HF功率（高频功率/总功率）被用作迷走神经活动调制的指标，并且LF/HF比率被用作 ...更多信息 作为交感神经活动调节的指标。同时，在状态结束后立即测量状态特质焦虑量表（STAI）X型状态。在胎儿中，进行FHR时域和多普勒检测胎动的数据分析。<Results>1）妊娠期妇女STAI在CWT时显著高于静息时，在GI时显著低于CWT（p&lt;0.001）。2)对于妊娠晚期的妇女，HF在CWT中显著低于静息时（p&lt;0.01），GI中显著高于CWT（p&lt;0.001），LF/HF在CWT中显著高于静息时（p&lt;0.01），GI中显著低于CWT（p&lt;0.01）。3)在活动期，基础胎心率在胃肠道显著低于CWT和静息时（p&lt;0.05），胎心率标准差（SD）和变异系数（CV）在胃肠道显著高于CWT和静息时（p&lt;0.05）。<Conclusion>这些结果表明，情绪变化在怀孕后期妇女影响自主神经活动和母亲的情绪可能会影响胎儿的反应。少
