The degree of fetal respiratory and body movements as well as of fetal heart rate reactivity was checked by synchronous ultrasonic and cardiographic monitoring of 18 normotrophic fetuses in the early and late dilation period. Apart from the fetal respiratory movements, which could no longer be observed in the late dilatation period, the degree of fetal body movements remained unaffected during the birth process. In the late dilatation period, the mean amplitude of heart rate accelerations occurring in association with fetal body movements was significantly lower than in the early dilatation period. In the unimpaired normotrophic fetus, however, the reactivity of the fetal cardiovascular system increased during the birth process in relation to the ratio of the amplitude of heart rate accelerations and the duration of associated fetal body movements. Hence, a decrease in fetal heart rate reactivity signals intranatal disturbance of the materno-utero-placento-fetal entity.
通过同步超声和心电图监测，对18例营养正常的胎儿在扩张早期和晚期进行检查，以了解胎儿呼吸运动、身体运动以及胎儿心率反应性的程度。除了在扩张晚期无法再观察到的胎儿呼吸运动外，胎儿身体运动的程度在分娩过程中未受影响。在扩张晚期，与胎儿身体运动相关的心率加速的平均幅度明显低于扩张早期。然而，在未受损的营养正常的胎儿中，胎儿心血管系统的反应性在分娩过程中相对于心率加速幅度与相关胎儿身体运动持续时间的比率有所增加。因此，胎儿心率反应性降低表明母-子宫-胎盘-胎儿系统在产时受到干扰。
