Randomized, Single-blind Pilot Study Assessing the Effect of Cutaneous RESonance Stimulation SYMPAthetic and Parasympathetic Tone and Anxiety in Patients Admitted for Cardiac Surgery

"If randomized in the RESC group, interventional group, patient will receive a 20 minutes session of cutaneous resonance stimulation before his cardiac surgery.~He will be asked to respond to anxiety questionnaire STAI-E and to evaluate his anxiety on a visual analogue scale (VAS) at J-1 (day of inclusion), J0 (day of surgery), and J1 (the day after surgery).~During the RESC session, LF/HF ratio, ANI, heart rate, respiratory rate, perfusion index and skin conductance will be monitored."
