Abstract:

Normalization of complexity measures based on surrogate approach overcomes the drawback of sensitivity of complexity measures to window length and sampling rate of signals.In this article,the authors normalized approximate entropy(ApEn) and C0 complexity that were most suitable for complexity analysis of biomedical signals.An application to ECG signals can reflect the difference between some heart diseases effectively.Meanwhile,through the comparison of kinds of complexity measures,it can be found that C0 complexity and approximate entropy(ApEn) have the weakest sensitivity to window length,so it can be used for signal analysis of short length data.
