Pilot Study to Evaluate the Somnotouch Device to Quantify Spontaneous Baroreflex Sensitivity

In each arm, we will evaluate the capacity of SOMNOtouch to measure the baroreflex sensitivity compared to Finapre Nova (reference)

"For each arm we will proceed to an orthostatic test day one and day two with :~* 10 minutes in supine position~* 10 minutes in sitting position~* 5 minutes in standing position~* 5 minutes in supine position"
