Summary

This study tests whether breathing through a special resistance device can help people with Postural Orthostatic Tachycardia Syndrome (POTS) stand up longer and reduce the rapid heart rate that happens when they stand. Researchers will measure heart rate changes and symptom relief in 30 adults diagnosed with POTS. The goal is to find a simple, non-drug way to improve daily life for those affected.
