| 摘 要： | 心率变异信号(HRV)是人体心脏搏动周期的微小变异,反映了自主神经系统的平衡协调关系.在证实心率变异信号的非线性特征后,可利用基于复杂度的非线性动力学分析方法-复原图(recurrence plot)来进行分析.通过复原图及其量化分析方法,发现与正常情况相比,缺血缺氧阶段HRV信号的复原图和量化指标L-Mean、L-Entr均有显著的变化,为监测缺血缺氧脑损伤提供了新的途径.

| Abstract: | Heart rate variability(HRV) is the tiny variability existing in the cycles of the heart beats,which reflects the corresponding balance between sympathetic and vagus nerves.Since the nonlinear characteristic of HRV is confirmed, the Recurrence Plot method,a nonlinear dynamic analysis method based on the complexity,could be used to analyze HRV.The results showed the recurrence plot structures and some quantitative indices(L-Mean,L-Entr) during asphyxia insult vary significantly as compared to those in normal conditions,which offer a new method to monitor brain asphyxia injury. |
