The contribution of nonlinear dynamics to heart rate variability in healthy humans was examined using surrogate data analysis. Several measures of heart rate variability were used and compared. Heart rates were recorded for three hours and original data sets of 8192 R-R intervals created. For each original data set (n=34), three surrogate data sets were made by shuffling the order of the R-R intervals while retaining their linear correlations. The difference in heart rate variability between… Expand

Effect of Threshold Value r on Multiscale Entropy based Heart Rate Variability
Heart rate variability (HRV) is the output of multiple physiological control mechanisms that occurs over a wide range of complex time scales. The multiscale entropy (MSE) of RR interval time seriesExpand
Modified permutation-entropy analysis of heartbeat dynamics.
TLDR
Results show that modified permutations entropy can greatly improve the ability to distinguish the HRV signals under different physiological and pathological conditions and characterize the complexity of HRV more effectively than the original permutation entropy. Expand
Decreased chaos of heart rate time series in children of patients with panic disorder
TLDR
Children of patients with panic disorder had significantly lower LLE of heart rate time series in supine posture, suggesting a relative decrease of cardiac vagal function in this group of children. Expand
Nonlinear measures of heart rate time series: influence of posture and controlled breathing
TLDR
Investigation of measures of nonlinear dynamics and chaos theory in regards to heart rate variability in 27 normal control subjects in supine and standing postures and 14 subjects in spontaneous and controlled breathing conditions found an improvement in predictability during controlled breathing appears to be due to the introduction of a periodic component. Expand
Nonlinear measures of QT interval series: novel indices of cardiac repolarization lability: MEDqthr and LLEqthr
TLDR
The lack of correlation between QTvi and LLEqthr suggests that this nonlinear index is a valuable addition to the linear measures, and may also help to explain the higher incidence of cardiovascular mortality in patients with anxiety and depressive disorders. Expand
Neuro-Fuzzy Approach to Heart Rate Variability Analysis
TLDR
The Neuro-fuzzy system is used to recognize the HRV signals for diagnosis by extract the QRST zone of ECG signals using Discrete Cosine Transform (DCT), and the result is exciting as it has used only one of ECGs lead to records input data, while the current diagnosis approaches require the set of 12 lead ECGs.

Nonlinear Dynamical Characterization of Heart Rate Variability Time Series of Meditation
TLDR
The study indicated highly nonlinear dynamic nature of cardiac states as revealed by HRV during meditation state, rather considering it as a quiescent state. Expand
On Entropy of Probability Integral Transformed Time Series
TLDR
The goal of this paper is to investigate the changes of entropy estimates when the amplitude distribution of the time series is equalized using the probability integral transformation, and derived an expression for the reference value of entropy in the probabilities integral transformed signals.

Nonlinear Measures of Respiration: Respiratory Irregularity and Increased Chaos of Respiration in Patients with Panic Disorder
TLDR
The findings support the previously described respiratory irregularity in patients with panic disorder and illustrate the utility of nonlinear measures such as APEN and LLE as additional measures toward a better understanding of the abnormalities of respiratory physiology in similar patient populations. Expand
Heart rate time series: decreased chaos after intravenous lactate and increased non-linearity after isoproterenol in normal subjects
TLDR
There was a significant increase in NL score, (S(netGS)) after isoproterenol infusions and a significant decrease in LLE (an increase in predictability indicating decreased chaos), after intravenous lactate in supine posture in normal control subjects, which may throw new light on the association of anxiety and significant cardiovascular events.

Short- and long-term variations in non-linear dynamics of heart rate variability.
TLDR
The study confirms that the correlation dimension of the R-R intervals is mostly due to linear correlations in the R -R intervals, and hypothesized that the heart rate is governed by a system with multiple "strange" attractors. Expand

These results suggest that changes in approximate entropy can distinguish between patients who sustained poor outcome and those who had an uncomplicated postoperative course. Expand

The ability of several short-term measures of RR variability to predict mortality after myocardial infarction.
TLDR
It is found that power spectral measures of RR variability calculated from short (2 to 15 minutes) ECG recordings are remarkably similar to those calculated over 24 hours and are excellent predictors of all-cause mortality and sudden cardiac death. Expand

TLDR
It is concluded that the PD2 of heartbeat intervals may provide an important diagnostic test and early warning signal for sudden cardiac death. Expand

TLDR
This work provides a formal mathematical description of approximate entropy and provides a multistep description of the algorithm as applied to two contrasting clinical heart rate data sets, indicating the utility of ApEn to test this hypothesis. Expand

TLDR
It is suggested that complex fluctuations in healthy heart rate may be due in part to deterministic chaos in the neuroautonomic control system, and perturbations of this control system may lead to a loss of complexity of heart rate dynamics. Expand

TLDR
Nonlinear Dynamics in Heart Rate finds that the variability observed in the normal heart rate may be due to chaos, but this question has not been settled. Expand
