| 摘 要： | 心率变异性（HRV）是当前心电图分析的一个前沿热点。目前HRV信号的分析法主要是线性分析法，非线性分析法则不多。本文综述了国内外心率变异分析方法的研究进展。重点分析了非线性分析方法的原理和特点，探讨了HRV信号的分形维数，复杂度和近似熵分析法。

| Abstract: | One of the hotspots in the analysis of ECG is heart rate variability (HRV). In the present, the method mostly used for the analysis of HRV signal is linear analysis, and nonlinear analysis seldom used. Research progress of several methods of HRV analysis is presented. Principles and characteristics of using nonlinear analysis for the study of HRV are analyzed in detail. Fractal dimension, complexity and approximate entropy are discussed. |
