本研究的目的是制定一个标准化的方案来测量6个月和12个月婴儿在休息和挑战状态下的射血前期（PEP），交感神经系统的测量，呼吸窦性心律失常（RSA），副交感神经系统的测量，并确定这些测量的发育变化和个体稳定性。对6个月（n = 194）和12个月（n = 181）的拉丁裔婴儿实施7分钟反应性方案。结果表明：(1)在婴儿中测量PEP和RSA是可行的；(2)该方案引起了显著的自主神经变化；(3)个体静息自主神经测量在6 ~ 12个月期间中度稳定，但反应性测量不稳定；(4)心率和RSA静息和挑战组均值在6 ~ 12个月期间发生了显著变化。研究结果表明，虽然婴儿的自主神经反应表现出发育变化，但个体的等级顺序在6 ~ 12个月前是稳定的。(c) 2006 Wiley期刊公司
The purpose of this study was to develop a standardized protocol to measure preejection period (PEP), a measure of sympathetic nervous system, and respiratory sinus arrhythmia (RSA), a measure of parasympathetic nervous system, during resting and challenging states for 6- and 12-month-old infants and to determine developmental changes and individual stability of these measures. A 7-min reactivity protocol was administered to Latino infants at 6 months (n = 194) and 12 months (n = 181). Results showed: (1) it is feasible to measure PEP and RSA in infants, (2) the protocol elicited significant autonomic changes, (3) individual resting autonomic measures were moderately stable from 6 to 12 months, but reactivity measures were not stable, and (4) heart rate and RSA resting and challenge group means changed significantly from 6 to 12 months. Findings suggest that although infants' autonomic responses show developmental changes, individuals' rank order is stable front 6 to 12 months of age. (c) 2006 Wiley Periodicals, Inc.
