NCT ID NCT03218761
First seen Nov 01, 2025 · Last updated Jun 13, 2026 · Updated 36 times
Summary
This study looks at whether a simple blood test can measure how well the body clears a chemical called norepinephrine in people with Postural Tachycardia Syndrome (POTS). POTS causes a rapid heart rate and other symptoms when standing. The study involves 200 people, some with POTS and some without, to see if the blood test matches older, more complex methods. The goal is to better understand POTS, not to test a new treatment.
