Network representation of cardiac interbeat intervals for monitoring restitution of autonomic control for heart transplant patients
Danuta Makowiec, Stanisław Kryszewski, Beata Graff +6
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-…
Multifractal age? Multifractal analysis of cardiac interbeat intervals in assessing of healthy aging
Danuta Makowiec, Stanisaw Kryszewski, Joanna Wdowczyk-Szulc +3
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 struct…
Multifractal analysis of normal RR heart-interbeat signals in power spectra ranges
Danuta Makowiec, Aleksandra Dudkowska, Rafal Galaska +1
Power spectral density is an accepted measure of heart rate variability. Two estimators of multifractal properties: Wavelet Transform Modulus Maxima and Multifractal Detrended Fluc…
Long-range dependencies in heart rate signals- revisited
Danuta Makowiec, Rafal Galaska, Aleksandra Dudkowska +2
The RR series extracted from human electrocardiogram signal (ECG) is considered as a fractal stochastic process. The manifestation of long-range dependencies is the presence of pow…
