We present a multifractal analysis of diurnal heart interbeat time series from healthy young subjects, healthy elderly subjects and patients with congestive heart failure (CHF). Aging and CHF causes loss of multifractality. We analyze the multifractal spectrum asymmetry. We show that the joint analysis of the degree of multifractality and the asymmetry parameter can differentiate between the cardiac interbeat time series of young and elderly persons and it can also separate healthy subjects and CHF patients.
我们对健康青年受试者、健康老年受试者和充血性心力衰竭（CHF）患者的日间心跳间期时间序列进行了多重分形分析。衰老和CHF会导致多重分形性丧失。我们分析了多重分形谱的不对称性。我们表明，对多重分形程度和不对称参数的联合分析可以区分青年人和老年人的心跳间期时间序列，也可以区分健康受试者和CHF患者。
