| Abstract: | Transient process analysis is one of the most challenging tasks in heart rate variability analysis.Wavelet transform has the ability to describe the transient characteristic of signal.In this paper,through wavelet transform,the Lipschitz exponent and smooth factor analysis of the transient edge of R?R interval,which is induced by rest-to-count experiment,is performed.It is found that the healthy testees' Lipschitz exponents are larger than the coronary heart disease patients'.The analysis results are explained simply. |
