摘要
目前关于心率变异性(HRV)的时域、频域及时频分析等线性分析方法已经取得很多共识,而针对HRV的非线性分析方法也在生物医学和临床医学上有不少的研究报道,尤其是短时HRV分析,但目前仍然存在很多争议,尚未形成统一的标准和结论。本文就短时HRV非线性分析常用的三种方法(分形维、熵及复杂度)的原理、临床应用进展及存在问题进行详细的综述和讨论,以期为准确地将其应用于临床医学提供参考。
The linear analysis for heart rate variability（HRV）,including time domain method,frequency domain method and time-frequency analysis,has reached a lot of consensus.The non-linear analysis has also been widely applied in biomedical and clinical researches.However,for non-linear HRV analysis,especially for short-term non-linear HRV analysis,controversy still exists,and a unified standard and conclusion has not been formed.This paper reviews and discusses three short-term non-linear HRV analysis methods（fractal dimension,entropy and complexity）and their principles,progresses and problems in clinical application in detail,in order to provide a reference for accurate application in clinical medicine.
