这项研究提供了学龄前儿童（4.5-5.5岁）和年轻人对常见实验室任务的心脏反应性的比较数据。我们使用了一系列任务（情感唤起视频，访谈，反应时间任务和冷前额加压器）来检查射血前期（成人交感神经心脏活动的常见估计）是否为学龄前儿童提供了对这些任务的交感神经反应的可比测量。我们的研究结果表明，儿童和年轻人对这些任务的心脏反应性（射血前期、呼吸性窦性心律失常和心脏期）相似，但儿童的交感神经反应性较小。个体内不同任务的反应一致性以及儿童和年轻人的反应一致性表明，射血前期是儿童交感神经活动的合理估计。
This study provides comparative data on cardiac reactivity to common laboratory tasks in preschool children (ages 4.5–5.5 years) and young adults. We used a series of tasks (an emotionally evocative video, interview, reaction time task, and cold forehead pressor) to examine whether pre‐ejection period, a common estimate of sympathetic cardiac activity in adults, provides a comparable measure of sympathetic reactivity to these tasks in preschool children. Our results demonstrate that the cardiac reactivity (pre‐ejection period, respiratory sinus arrhythmia, and heart period) to such tasks in children and young adults is similar, but with smaller sympathetic reactivity in children. The consistency of the reactivity across tasks within individuals and consistency of reactivity across children and young adults suggests that pre‐ejection period is a reasonable estimate of sympathetic activity in children.
