Summary
This pilot study tests a non-invasive ear stimulation device (aVNT) in 30 people with Postural Orthostatic Tachycardia Syndrome (POTS). The goal is to see if it can reduce rapid heart rate upon standing, improve blood flow to the brain, and ease other symptoms like brain fog and fatigue. Participants will be randomly assigned to receive either active stimulation or a sham (placebo) device for 3 months.
