Summary

This trial will test if an autoimmune reaction is the cause of symptoms in some patients with POTS, and if electrical stimulation of the vagus nerve can help.

Who is the study for?
This trial is for adults aged 18-80 with Postural Tachycardia Syndrome (POTS), characterized by a rapid heartbeat upon standing, without other causes of orthostatic tachycardia. Healthy controls must be non-smoking and not on chronic medications. Excluded are those with recent heart attacks, significant immune or blood disorders, pregnancy, pacemakers or cochlear implants, severe hypertension, history of vagotomy.
What is being tested?
The study aims to see if stimulating the vagus nerve can improve symptoms in POTS patients by potentially reducing autoimmune reactions and inflammation. Participants will receive either actual vagal stimulation or sham (fake) stimulation to compare effects.
What are the potential side effects?
While specific side effects aren't listed here, generally speaking, vagal stimulation might cause discomfort at the site of stimulation, changes in voice tone due to laryngeal muscle activation and possible temporary changes in heart rate.
