Cardiac Vagal Effects of Gastric Electrical Stimulation and Vagal Nerve Action Potentials in Vagus nerve in Patients with Gastroparesis- Randomized Phase


The purpose of this study is to assess if the Gastric Electric Stimulator (GES) device may influence the vagal output, which helps in the relief of the symptoms of gastroparesis, mainly nausea and vomiting.


The primary objective is to find if Gastric electrical stumulation (GES) may influence the flow in the vagus nerve when the signals are sent by the GES. Specifically this study will determine whether programming the GES device to produce optimal CNAPs results in better resolution of symptoms than empiric increases in stimulus current and frequency.

  • Conditions: gastroparesis,1712391546

  • Gender: Male or Female

Inclusion Criteria
