The aim of the study is to evaluate autonomic function and cerebrovascular control in 60 healthy subjects by means of noninvasive analysis of time series variability.
To this extent, heart period, systolic and mean arterial blood pressure, cerebral blood velocity, peripheral resistances, respiration will be recorded from subjects during an orthostatic challenge.
The interactions between autonomic cardiovascular function, cerebrovascular and peripheral control will be evaluated exploiting the most advanced signal processing techniques.
