| 摘 要： | 目的对不同子宫收缩状态下，分析胎儿心率变异性的非线性混沌强度。方法采用非线性滴定方法，计算胎儿心率变异性的噪声极限，即非线性混沌强度；另用近似熵方法计算宫缩状态下胎儿心率变异性的复杂性。结果统计结果表明宫缩频率越高，计算所得到的噪声极限越大。说明随着外加刺激的增强，胎儿心率变异性的非线性混沌强度是增大的。但是近似熵方法不能反映相似的结果，宫缩反而使胎儿心率变异性的复杂性降低。

| Abstract: | Objective To investigate the nonlinearity of fetal heart rate variability (FHRV) under the dif- ferent conditions of uterine contraction.Method The noise limits (NL) of FHRV were calculated by using non- linear titration method based on Volterra-Weiner series;as a comparison the FHRV were also analyzed by approxi- mate entropy (ApEn) to investigate the change of the complexity of FHRV.Results The noise limits of FHRV were dependent on the frequency of uterine contraction.It indicates that the FHRV is transi... |
