Blood Pressure Variability and Closed-Loop Baroreflex Assessment in Adolescent Chronic Fatigue Syndrome During Supine Rest and Orthostatic Stress
Wyller, Vegard Bruun; Barbieri, Riccardo; Saul, J. Philip (Springer-Verlag, 2010)Hemodynamic abnormalities have been documented in the chronic fatigue syndrome (CFS), indicating functional disturbances of the autonomic nervous system responsible for cardiovascular regulation. The aim of this study was ... -
Editorial: engineering approaches to study cardiovascular physiology: modeling, estimation, and signal processing
Chen, Zhe; Barbieri, Riccardo (Frontiers Media S.A., 2012) -
Estimation of Instantaneous Complex Dynamics through Lyapunov Exponents: A Study on Heartbeat Dynamics
Valenza, Gaetano; Citi, Luca; Barbieri, Riccardo (Public Library of Science, 2014)Measures of nonlinearity and complexity, and in particular the study of Lyapunov exponents, have been increasingly used to characterize dynamical properties of a wide range of biological nonlinear systems, including ... -
Nonlinear digital signal processing in mental health: characterization of major depression using instantaneous entropy measures of heartbeat dynamics
Valenza, Gaetano; Garcia, Ronald G.; Citi, Luca; Scilingo, Enzo P.; Tomaz, Carlos A; Barbieri, Riccardo (Frontiers Media S.A., 2015)Nonlinear digital signal processing methods that address system complexity have provided useful computational tools for helping in the diagnosis and treatment of a wide range of pathologies. More specifically, nonlinear ... -
Revealing Real-Time Emotional Responses: a Personalized Assessment based on Heartbeat Dynamics
Valenza, Gaetano; Citi, Luca; Lanatá, Antonio; Scilingo, Enzo Pasquale; Barbieri, Riccardo (Nature Publishing Group, 2014)Emotion recognition through computational modeling and analysis of physiological signals has been widely investigated in the last decade. Most of the proposed emotion recognition systems require relatively long-time series ... -
A Unified Point Process Probabilistic Framework to Assess Heartbeat Dynamics and Autonomic Cardiovascular Control
Chen, Zhe; Purdon, Patrick Lee; Brown, Emery Neal; Barbieri, Riccardo (Frontiers Research Foundation, 2012)In recent years, time-varying inhomogeneous point process models have been introduced for assessment of instantaneous heartbeat dynamics as well as specific cardiovascular control mechanisms and hemodynamics. Assessment ...
