Skin Sympathetic Nerve Activity and Cardiac Arrhythmia

Skin Sympathetic Nerve Activity and Cardiac Arrhythmia

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
