摘要
本文提出了一种最优符号动态变换方法来分析大鼠窒息实验中心率变异性(HRV)的动态方面。利用近似熵(ApEn)来量化由5 min R-R区间(RRI)得到的短符号序列的规律性。在HRV分析中应用的几种符号变换的比较表明，我们的方法是表征大鼠窒息后恢复过程中不同阶段之间转换的最佳方法。
Heart period dynamics following an asphyxia experiment in rats
The present work proposes an optimal symbol dynamics transformation as an approach to analyze dynamic aspects of heart rate variability (HRV) in an asphyxia experiment in rats. The approximate entropy (ApEn) was used to quantify the regularity of short symbolic sequences derived from 5 min R-R intervals (RRI). The comparison of several symbol transformations applied in HRV analysis indicates our approach as optimal for characterizing the transitions between different phases in the recovery process following asphyxia in rats.
