Age-related alterations in the fractal scaling of cardiac interbeat interval dynamics.
We postulated that aging is associated with disruption in the fractallike long-range correlations that characterize healthy sinus rhythm cardiac interval dynamics. Ten young (21-34 yr) and 10 elderly (68-81 yr) rigorously screened healthy subjects underwent 120 min of continuous supine resting electrocardiographic recording. We analyzed the interbeat interval time series using standard time and...
متن کاملMultifractality and scale invariance in human heartbeat dynamics.
Human heart rate is known to display complex fluctuations. Evidence of multifractality in heart rate fluctuations in healthy state has been reported [Ivanov, Nature (London) 399, 461 (1999)]. This multifractal character could be manifested as the dependence of the probability density functions (PDFs) of the interbeat interval increments, which are the differences in two interbeat intervals that...
متن کاملStatistical physics and physiology: monofractal and multifractal approaches.
Even under healthy, basal conditions, physiologic systems show erratic fluctuations resembling those found in dynamical systems driven away from a single equilibrium state. Do such "nonequilibrium" fluctuations simply reflect the fact that physiologic systems are being constantly perturbed by external and intrinsic noise? Or, do these fluctuations actually, contain useful, "hidden" information ...
متن کاملUnexpected Course of Nonlinear Cardiac Interbeat Interval Dynamics during Childhood and Adolescence
The fluctuations of the cardiac interbeat series contain rich information because they reflect variations of other functions on different time scales (e.g., respiration or blood pressure control). Nonlinear measures such as complexity and fractal scaling properties derived from 24 h heart rate dynamics of healthy subjects vary from childhood to old age. In this study, the age-related variations...
متن کاملتحلیل سیگنالهای الکتریکی قلب (ECG) با روش حذف شیب چند فرکتالی
In recent years cardiac interbeat interval time series have been investigated by DFA and MF-DFA methods. In this paper instead of investigating cardiac interbeat interval time series, ECG signals are considered, it is shown that the normal and abnormal heart signals have different scaling relations.
