Objective: There is an ongoing research effort devoted to characterize the signal regularity metrics approximate entropy (ApEn) and sample entropy (SampEn) in order to better interpret their results in the context of ...
Signal entropy measures such as Approximate Entropy (ApEn) and Sample Entropy (SampEn) are widely used in Heart Rate Variability (HRV) analysis and biomedical research. In this article, we analyze the influence of QRS ...
