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

Enrolling: Yes

Principle Investigator: Thomas Nowak, MD

Duration: TBD

Primary Outcomes Measured:The objective of this study is to determine if GES may influence vagal outflow via vagal afferent fibers that terminate in the Central Nervous System (CNS).

Secondary Outcomes Measured:To determine whether programming the GES device to produce optimal CNAPs results in better resolution of symptoms than empiric increases in stimulus current and frequency.
