Research Studies

We are currently recruiting for the following research studies. Participants must be at least 18 years of age.


Body Compression in POTS: Effects on Orthostatic Intolerance

A study investigating the effects of abdominal and leg compression on orthostatic heart rate change and orthostatic symptoms in individuals diagnosed with POTS.  A segmented, non-inflatable compression garment (neoprene with velcro straps) will be used to apply compression to all or portions of the lower body.

The Pathophysiological Role of Adrenergic Antibodies in POTS

A pilot study involving autonomic function testing (AIM #1), small doses of short acting medications (AIM #2), and a longer medication trial (AIM #3) to evaluate the role of antibodies in cardiovascular regulation in POTS patients as compared to healthy volunteers. POTS participants are invited back for follow-up examination one year following the study. All participants are required to complete an online questionnaire.

Recently Completed Research Studies

Prevention of Syncope Trial VI (POST 6)

A placebo-controlled proof of principle study in patients with recurrent vasovagal syncope, to examine whether the drug Atomoxetine will better prevent syncope in head up tilt testing than placebo. Atomoxetine is a drug that is currently approved for the treatment of attention-deficit hyperactivity disorder (ADHD).
