The relationship between fetal movements and fetal heart rate accelerations was analyzed in 34 healthy near term fetuses. Periods of coincidence 2F (C2F) with a mean duration of 34 +/- 6 minutes per fetus were selected, with a total of 463 accelerations. Nineteen percent of single body movements and 71% of compilations of movements were accompanied by an acceleration. The minimal duration of single movements associated with accelerations was 4-5 seconds. Movements with associated accelerations differed significantly in duration from movements without accelerations. The duration of accelerations was strongly correlated with the duration of movements. The amplitude of accelerations was not clearly correlated with the duration of movements, but depended on the type of movement. The shape of accelerations appeared to be dependent on the timing of the various fetal movements. In 77%, the number of notches in the accelerations was equal to the number of pauses in the movement complications. A discrepancy between notches in accelerations and pauses in movements could be explained in the majority of cases when the timing of the various movements in relation to one another was considered, or by the presence of fetal mouth movements.
对34例健康足月胎儿的胎动与胎心率加速之间的关系进行了分析。选择每个胎儿平均持续时间为34±6分钟的同时发生期2F（C2F），共有463次加速。19%的单个体运动和71%的运动组合伴有加速。与加速相关的单个体运动的最短持续时间为4-5秒。伴有加速的运动在持续时间上与无加速的运动有显著差异。加速的持续时间与运动的持续时间密切相关。加速的幅度与运动的持续时间没有明显的相关性，但取决于运动的类型。加速的形状似乎取决于各种胎动的时间。在77%的情况下，加速中的切迹数量与运动组合中的停顿数量相等。当考虑各种运动相互之间的时间关系，或存在胎儿口部运动时，在大多数情况下可以解释加速中的切迹与运动中的停顿之间的差异。
