POSTURAL TACHYCARDIA SYNDROME

This study looks at whether moxonidine, a drug that lowers sympathetic nerve activity, can reduce symptoms like rapid heartbeat and lightheadedness in people with Postural Tachycardia Syndrome (POTS). About 48 women with POTS will take either moxonidine or a placebo for 4 weeks. …

This study tests whether breathing through a small resistance device can help people with Postural Orthostatic Tachycardia Syndrome (POTS) stand up longer and feel better. POTS causes a rapid heart rate and symptoms like dizziness when standing. The study involves 30 adults diagn…

This study looks at whether a simple saltwater infusion can help people with Postural Tachycardia Syndrome (POTS) exercise more easily. Forty adults with POTS will have their exercise ability tested after receiving either saline or a placebo. The goal is to see if the saline impr…

This study looks at how the body handles salt and a hormone called aldosterone in people with Postural Tachycardia Syndrome (POTS). Researchers want to see if a high-salt diet can improve symptoms and blood volume. The study involves both POTS patients and healthy volunteers to c…

This study looks at whether postural tachycardia syndrome (POTS) is caused by an autoimmune reaction. Researchers will test if stimulating the vagus nerve can reduce symptoms and inflammation. The study involves 80 people, including those with POTS and healthy volunteers.

This study looks at whether a simple blood test can measure how well the body clears a stress chemical called norepinephrine in people with Postural Tachycardia Syndrome (POTS). POTS causes a rapid heart rate and dizziness when standing. The researchers will compare blood and uri…

This study looks at why people with Postural Tachycardia Syndrome (POTS) often have trouble thinking clearly, known as 'brain fog.' Researchers will compare brain scans of 21 adults with and without POTS while they do mental tasks, both sitting and standing. The goal is to see if…

This study looks at whether people with Postural Orthostatic Tachycardia Syndrome (POTS) have trouble holding onto salt in their urine compared to healthy people. Researchers will measure salt and stress hormone levels after a salt load. The goal is to better understand the body'…

This study looks at whether a single dose of modafinil, a drug that promotes wakefulness, can improve concentration and mental clarity in people with Postural Tachycardia Syndrome (POTS). Twenty adults diagnosed with POTS will take the drug and then complete computer-based tests …

This study looks at why people with Postural Tachycardia Syndrome (POTS) get a fast heart rate and feel dizzy when standing. Researchers will give a blood pressure drug called moxonidine to 48 adults with POTS to see if lowering nerve activity eases symptoms. The goal is not to c…

This study looks at whether people with POTS (a condition causing a rapid heart rate upon standing) have higher levels of certain immune proteins that might attack their own nervous system. Researchers will measure these proteins in blood samples from 58 participants, including b…

This study uses activity watches (actigraphy) to measure sleep disturbances in people with orthostatic intolerance, a condition where standing causes dizziness or fainting. Researchers will compare sleep quality between 100 patients and healthy volunteers. The goal is to understa…
