Journal ArticleDOI
Power spectrum analysis of heart rate variability to assess the changes in sympathovagal balance during graded orthostatic tilt.
Nicola Montano,Tomaso Gnecchi Ruscone,Alberto Porta,Federico Lombardi,Massimo Pagani,Alberto Malliani +5 more
TL;DR: Spectral analysis of HRV, using nu or LF-to-HF ratio, appears to be capable of providing a noninvasive quantitative evaluation of graded changes in the state of the sympathovagal balance.
Journal ArticleDOI
Relationship Between Spectral Components of Cardiovascular Variabilities and Direct Measures of Muscle Sympathetic Nerve Activity in Humans
Massimo Pagani,Nicola Montano,Alberto Porta,Alberto Malliani,Francois M. Abboud,Clay Birkett,Virend K. Somers +6 more
TL;DR: There is a predominance in the LF oscillation of blood pressure, RR interval, and sympathetic nerve activity during sympathetic activation in normal humans and during sympathetic inhibition, the HF component of cardiovascular variability predominates.
Journal ArticleDOI
Entropy, entropy rate, and pattern classification as tools to typify complexity in short heart period variability series
Alberto Porta,Stefano Guzzetti,Nicola Montano,Raffaello Furlan,M. Pagani,Alberto Malliani,S. Cerutti +6 more
TL;DR: The proposed approach based on quantification of complexity allows a full characterization of heart period dynamics and the identification of experimental conditions known to differently perturb cardiovascular regulation.
Journal ArticleDOI
Heart rate variability explored in the frequency domain: A tool to investigate the link between heart and behavior
Nicola Montano,Alberto Porta,Chiara Cogliati,Giorgio Costantino,Eleonora Tobaldini,Karina Rabello Casali,Ferdinando Iellamo +6 more
TL;DR: The development of new non-linear approaches seems to provide a new perspective in investigating neural control of cardiovascular system as linear methodologies fail to provide significant information in conditions of extremely reduced variability.
Journal ArticleDOI
Comparison of various techniques used to estimate spontaneous baroreflex sensitivity (the EuroBaVar study)
Dominique Laude,Jean Luc Elghozi,Arlette Girard,Elisabeth Bellard,Malika Bouhaddi,Paolo Castiglioni,Catherine Cerutti,Andrei Cividjian,Marco Di Rienzo,Jacques Olivier Fortrat,Ben J. A. Janssen,John M. Karemaker,Georges Lefthériotis,Gianfranco Parati,Pontus B. Persson,Alberto Porta,Luc Quintin,Jacques Regnard,Heinz Rüdiger,Harald M. Stauss +19 more
TL;DR: The discrepancies between procedures show that the choice of parameters and data handling should be considered before BRS estimation, and new techniques with this set of results are needed.
