Noninvasive blood flow and heart tests for dizziness on standing
Part of Brain & nervous system clinical trials.
This trial studies a noninvasive monitoring method that measures blood flow and heart function while testing how your body responds to standing up. It may help improve how doctors check “autonomic function” in people who get symptoms with postural (standing) intolerance.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You can sign a consent form to join the study
- Blood flow to both hands is adequate (you pass the Allen’s test on both hands)
- You have symptoms when standing (orthostatic intolerance)
- You do not have certain blood-vessel conditions or poor circulation in your arms/hands

This study tests a new approach to help people who feel dizzy or faint when standing up, especially if standard treatments haven't worked. It aims to improve daily life and reduce risks from low blood pressure.
This trial looks at how blood pressure and heart rate change when standing up or exercising in healthy people and in older adults with high blood pressure. It aims to understand how the body's automatic (autonomic) nervous system controls these functions.
This study uses a noninvasive bioelectronic device to record your body’s automatic (involuntary) signals. The goal is to see how well the device can analyze these signals and how your body responds in a controlled setting.
This study measures how breathing patterns and heart rate/blood pressure change when you move from lying to standing in people with POTS. It may help researchers understand symptoms better and improve ways to manage them.
This study looks at how your heart and blood vessels work together when blood flow to your legs is reduced using a special chamber. It compares younger and older adults, and men and women, especially after light exercise.
This study checks how your body controls breathing and heart rate when you stand up, especially if you get dizzy from low blood pressure. It may help researchers understand what causes symptoms and how to improve testing for people with this condition.
