Clinical Trial Summary

The Non-invasive Vagus Nerve Stimulation in Patients Undergoing Electrophysiological Study is a single center, pilot, prospective study that aims at evaluating the effects of auricular vagus nerve stimulation (aVNS) on the human cardiac conduction system.

Description:

The Non-invasive Vagus Nerve Stimulation in Patients Undergoing Electrophysiological Study is a single center, pilot, prospective study that aims at evaluating the effects of auricular vagus nerve stimulation (aVNS) on the human cardiac conduction system. In this study, we will enroll 10 healthy individuals presenting to the electrophysiology laboratory for an electrophysiological study (EPS). Patients will undergo a standard EPS with 4 catheters (coronary sinus catheter, His catheter, right ventricular catheter, and right atrial catheter). Following the standard EPS, patients will be hooked up a Parasym device to provide transcutaneous electrical stimulation to the auricular branch of the vagus nerve.
