UNLABELLED We aimed to study heart rate time irreversibility--a nonlinear qualitative characteristics of heart rate variability indicating complexity of cardiac autonomic control at rest and in response to physiological stress (orthostasis) in never-treated major depressive disorder (MDD) adolescent female patients. METHODS We studied 20 MDD girls and 20(More)
The aim of this study was to investigate the short-term heart rate variability (HRV) as an index of the cardiac autonomic control development in healthy full-term neonates using various new complexity and irreversibility measures. HRV in 20 healthy full-term neonates was compared to HRV recorded in healthy young adults. Besides traditional time and(More)
Introduction: Time irreversibility is a characteristic feature of non-equilibrium, complex systems including cardiovascu-lar control mediated by the autonomic nervous system. Its analysis in heart rate variability (HRV) signal represents a new approach to assess cardiovascular regulatory mechanisms. Aim: The purpose of this paper was to assess the changes(More)
