Physiological time-series analysis: what does regularity quantify?

Approximate entropy (ApEn) is a recently developed statistic quantifying regularity and complexity that appears to have potential application to a wide variety of physiological ...

Predicting Survival in Heart Failure Case and Control Subjects by Use of Fully Automated Methods for Deriving Nonlinear and Conventional Indices of Heart Rate Dynamics

Background Despite much recent interest in quantification of heart rate variability (HRV), the prognostic value of conventional measures of HRV and of newer indices based on non...

Gender- and age-related differences in heart rate dynamics: Are women more complex than men?

Heart Rate Dynamics in Patients With Stable Angina Pectoris and Utility of Fractal and Complexity Measures

Effects of head-down bed rest on complex heart rate variability: response to LBNP testing

Head-down bed rest is used to model physiological changes during spaceflight. We postulated that bed rest would decrease the degree of complex physiological heart rate variabili...
