Summary
This study aims to understand the body's response to standing in people with orthostatic intolerance, a condition that causes symptoms like rapid heartbeat, dizziness, and fatigue. Researchers will measure heart rate, blood volume, and nerve function in 260 participants to uncover the underlying causes. The goal is to better understand the condition, not to test a new treatment.
