摘要
本文应用计算机化自主神经系统功能测试系统对１０５例正常健康儿童（０～１１岁）进行了心动周期信号混沌特征分析。结果：除ＨＣＣ外，学龄儿童组的四个混沌特征参数均高于学龄前儿童组，新生儿则低于学龄组和学龄前组；功率谱参数学龄儿童组也高于学龄前儿童组。上述结果表明：儿童自主神经系统的发育，是随着年龄的增加而不断成熟的。
The chaotic characteristics of heart period signal for 105 cases of normal children were analyzed with a computerized analysis system for autonomic function.The results showed that these parameters of HPS for school age children were higher than preschool children except for HCC and RLH.But the 4 chaotic Characteristic parameters for neonatal were lower than school age and preschool children.
