Abstract

The work presents an algorithm for mathematical modeling long-term Heart Rate Variability data using Gaussian distribution functions. The representation of the cardiac series in time domain is performed using an inverse wavelet transform. The transform is implemented with different Daubechies wavelet bases and is compared with the implementation of the algorithm with the classical Fourier transform. The created time sequences are analyzed in terms of the wavelet bases (Db4, Db6, Db8, Db12, Db20) used and the required CPU time for implementation of the program procedure. The obtained results show higher IT efficiency of the presented algorithm, realized with Daubechies transform.

用高斯分布函数模拟长期心率变异性记录
提出了一种利用高斯分布函数对长期心率变异性数据进行数学建模的算法。心脏序列的时域表示是用小波反变换进行的。利用不同的小波基实现了该变换,并与经典的傅里叶变换实现算法进行了比较。根据所使用的小波基(Db4, Db6, Db8, Db12, Db20)和实现程序过程所需的CPU时间来分析所创建的时间序列。结果表明,采用Daubechies变换实现的算法具有较高的IT效率。
