Abstract

We present several recent studies based on statistical physics concepts that can be used as diagnostic tools for heart failure. We describe the scaling exponent characterizing the long-range correlations in heartbeat time series as well as the multifractal features recently discovered in heartbeat rhythm. It is found that both features, the long-range correlations and the multifractility, are weaker in cases of heart failure.

摘要

我们展示了几项基于统计物理概念的近期研究，这些研究可用作心力衰竭的诊断工具。我们描述了表征心跳时间序列中长程相关性的标度指数，以及最近在心跳节律中发现的多重分形特征。研究发现，在心力衰竭的情况下，长程相关性和多重分形性这两个特征都较弱。
