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 frequency domain statistics and using a fractal measure, detrended fluctuation analysis, to quantify…

Unexpected Course of Nonlinear Cardiac Interbeat Interval Dynamics during Childhood and Adolescence

The course of long-term fractal scaling properties and complexity of heart rate dynamics during childhood and adolescence indicates that these measures reflect complex changes possibly linked to hormonal changes during pre-puberty and puberty.

Fractal scale-invariant and nonlinear properties of cardiac dynamics remain stable with advanced age: a new mechanistic picture of cardiac control in healthy elderly.

Although the results indeed show a reduced SD of heart beat fluctuations with advanced age, the inherent temporal fractal and nonlinear organization of these fluctuations remains stable, indicating that the coupled cascade of nonlinear feedback loops, which are believed to underlie cardiac neuroautonomic regulation, remains intact withAdvanced age.

Quantifying Fractal Dynamics of Human Respiration : Age and Gender Effects

Evidence is provided for fractal organization in physiologic human breathing cycle dynamics, and for their degradation in elderly men, which may have implications for modeling integrated respiratory control mechanisms, quantifying their changes in aging or disease, and assessing the outcome of interventions aimed toward restoring normal physiologic respiratory dynamics.

Quantifying Fractal Dynamics of Human Respiration: Age and Gender Effects

Evidence for fractal organization in physiologic human breathing cycle dynamics, and for their degradation in elderly men are provided, may have implications for modeling integrated respiratory control mechanisms, quantifying their changes in aging or disease, and assessing the outcome of interventions aimed toward restoring normal physiologic respiratory dynamics.

Fractal properties of human heart period variability: physiological and methodological implications

Fractal scaling exponents are not reproducible within individuals and do not reliably reflect the autonomic mechanisms responsible for heart period variability, and data from combined blockade suggest that physiological effects of autonomic outflow may mask intrinsic fractal behaviour of the sinoatrial node.

Cardiac interbeat interval dynamics from childhood to senescence : comparison of conventional and new measures based on fractals and chaos theory.

Cardiac interbeat interval dynamics change markedly from childhood to old age in healthy subjects, and children show complexity and fractal correlation properties of R-R interval time series comparable to those of young adults, despite lower overall heart rate variability.

Aging effects on cardiac and respiratory dynamics in healthy subjects across sleep stages.

The age dependence of alpha1 should be considered when using this value for diagnostic purposes in post-infarction patients, as it possibly indicates an increased cardiovascular risk with aging and during REM and deep sleep.

Scale-Invariant Aspects of Cardiac Dynamics

  • Biology
It is hypothesized that, in addition to the known periodic rhythms with a characteristic time scale, the endogenous mechanisms of sleep and circadian regulation may influence cardiac dynamics over a broad range of time scales, and thus could lead to systematic changes in the scaling properties of the heartbeat fluctuations.

Fractal and Complexity Measures of Heart Rate Variability

Although concepts of chaos theory, fractal mathematics, and complexity measures of heart rate behavior in relation to cardiovascular physiology or various cardiovascular events are still far away from clinical medicine, they are a fruitful area for future research to expand knowledge concerning the behavior of cardiovascular oscillations in normal healthy conditions as well as in disease states.

Quantification of scaling exponents and crossover phenomena in nonstationary heartbeat time series.

A new method--detrended fluctuation analysis (DFA)--for quantifying this correlation property in non-stationary physiological time series is described and application of this technique shows evidence for a crossover phenomenon associated with a change in short and long-range scaling exponents.

Is walking a random walk? Evidence for long-range correlations in stride interval of human gait.

It is demonstrated that conventional models of gait generation fail to reproduce the observed scaling behavior and a new type of central pattern generator model is introduced that successfully accounts for the experimentally observed long-range correlations.

Heart rate variability and fractal dimension during orthostatic challenges.

Heart rate variability (HRV) spectral analysis has been used as a tool for short-term assessment of parasympathetic (PNS) and sympathetic nervous system (SNS) control of heart rate. However, it has

Analysis of long term heart rate variability: methods, 1/f scaling and implications.

The use of spectral techniques to quantify short term heart rate fluctuations on the order of seconds to minutes has helped define the autonomic contributions to beat-to-beat control of heart rate, and these techniques were used to quantify the entire spectrum during 24 hour ambulatory ECG monitoring.

Age-related changes in the "complexity" of cardiovascular dynamics: A potential marker of vulnerability to disease.

Changes in the "complexity" of cardiovascular dynamics reflect the breakdown and decoupling of integrated physiologic regulatory systems with aging, and may signal an impairment in cardiovascular ability to adapt to external and internal perturbations.

Spectral characteristics of heart rate variability before and during postural tilt. Relations to aging and risk of syncope.

A novel way to quantify the loss of autonomic influences on HR regulation as a function of age is illustrated by the regression lines relating the log amplitude to the log frequency of the supine HR spectra of the old subjects.

Long-range anticorrelations and non-Gaussian behavior of the heartbeat.

It is found that the successive increments in the cardiac beat-to-beat intervals of healthy subjects display scale-invariant, long-range anticorrelations (up to 10(4) heart beats), and the different scaling behavior in health and disease must relate to the underlying dynamics of the heartbeat.

Loss of 'complexity' and aging. Potential applications of fractals and chaos theory to senescence.

If further research supports this hypothesis, measures of complexity based on chaos theory and the related geometric concept of fractals may provide new ways to monitor senescence and test the efficacy of specific interventions to modify the age-related decline in adaptive capacity.

Effects of age on intrinsic heart rate, heart rate variability, and AV conduction in healthy humans.

It is concluded that age differences in heart rate variability can be explained by autonomic influences, but heart rate and AV conduction differences exist independently of beta-adrenergic and/or parasympathetic influences.

Finite-size effects on long-range correlations: implications for analyzing DNA sequences.

It is found that the DNA exponent fluctuations are consistent with those obtained from the control sequences having long-range power-law correlations, and the original "DNA-walk" method is intrinsically more accurate due to reduced noise.
