Multifractal age? Multifractal analysis of cardiac interbeat intervals in assessing of healthy aging

24-hour Holter recordings of 124 healthy people at different age are studied. The nocturnal signals of young people reveal the presence of the multiplicative structure. This structure is significantly weaker in diurnal signals and becomes less evident for elderly people. Multifractal analysis allows us to propose qualitative and quantitative methods to estimate the advancement of the aging process for healthy humans.

Network representation of cardiac interbeat intervals for monitoring restitution of autonomic control for heart transplant patients

The aim is to present the ability of a network of transitions as a nonlinear tool providing a graphical representation of a time series. This representation is used for cardiac RR-intervals in follow-up observation of changes in heart rhythm of patients recovering after heart transplant.
