Summary

This study tests a device that stimulates a nerve in the ear to see if it can help people with POTS, a condition that causes a racing heart and dizziness when standing. Twenty-four adults with POTS will receive both active and sham stimulation in a crossover design. The main goal is to measure changes in heart rate during a standing test.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Transcutaneous auricular vagus nerve stimulation (tVNS) device
What this could lead to: If it works, this could point toward a non-drug treatment to reduce rapid heartbeat and other symptoms in people with POTS.
What could go wrong: This is a very small, early-stage trial with only 24 participants. The effect may be small or not work at all, and results may not apply to everyone with POTS.
