Skin Sympathetic Nerve Activity and Cardiac Arrhythmia (SKNA)

Sympathetic tone is important in cardiac arrhythmogenesis. The simultaneous recording of sympathetic nerve activity (SNA) and electrocardiogram (ECG) was obtained by invasive method. The purpose of this protocol is to further develop this recording method to turn it into a new non-invasive tool for arrhythmia prediction and detection. This method may also be useful in validating the results of surgical procedures aimed at sympathetic denervation

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: SKNA group	Device: SKNA recording; The coupled recording of the sympathetic nervous activity of the skin and of an ECG will be carried out using the ME6000 device, CE marked, from the Bittium company. It will be performed for a maximum period of one hour at Day 1, Post-procedure between Day 1 and discharge from hospital, and month 6
