为了分析不同生理状态下人体心率变异性的差异性
并弥补传统心率变异性分析方法时间尺度特征单一的不足
本文结合了互补式集合平均经验模态分解和改进的排列熵算法对心率变异时间序列进行了具有多时间尺度特征的排列熵分析
并计算得到反映心率变异显著差异性的指标CEEMD-mPE. 最后基于MIT-BIH心率失常数据库的实验结果分析表明
本文所使用的心率变异性分析方法相比于其他基于熵的分析方法具有更优异的表现.
For analyzing the differences in human heart rate variability under different physiological conditions
and overcoming the problem of analyzing with only single time scale in traditional heart rate variability analysis methods
an HRV analysis method combining the complementary ensemble empirical mode decomposition and modified permutation entropy algorithm is proposed to obtain an indicator named CEEMD-mPE for measuring the obvious differences from HRV time series. The experimental results based on the MIT-BIH arrhythmia database show that our proposed HRV analysis method outperforms the other existing methods based on entropy.
