The investigators will test whether an intravenous infusion of saline (salt water) will improve the exercise capacity in patients with postural tachycardia syndrome (POTS).

Postural Tachycardia Syndrome

This is a 3-day study comparing pyridostigmine versus placebo in the treatment of postural tachycardia syndrome (POTS). The researchers expect pyridostigmine to improve tachycardia and st...
The investigators will test the hypothesis that patients with chronic orthostatic intolerance or postural orthostatic tachycardia syndrome (OI or POTS) will be unable to conserve urinary s...
The purpose of this study is to determine the role of the renin-angiotensin-aldosterone in the pathophysiology of postural tachycardia syndrome, and to provide an insight about the disease...
Postural orthostatic tachycardia syndrome (POTS) occurs in approximately 500,000 Americans, but predominates in women with a 5:1 ratio. Patients with POTS experience debilitating tachycard...
The investigators will test whether breathing through an inspiratory resistance device will improve the ability to be upright and decrease heart rate increases on standing in patients with...
Postural orthostatic tachycardia syndrome (POTS) impacts millions of patients, but there is currently no gold standard treatment for this condition. Ivabradine is a novel heart rate (HR) lowering agen...
To explore the clinical characteristics of the co-morbidity of vasovagal syncope (VVS) and postural tachycardia syndrome (POTS) with allergic diseases in children.
Bascule syndrome is a recently described benign vasomotor dermatosis characterized by Bier anemic spots, cyanosis, and urticaria-like eruption. We report a case of a 13-year-old girl with cutaneous le...
Youth with Down syndrome are characterized by motor delays when compared to typically developing (TD) youth, which may be explained by a lower postural control or reduced postural tone.
A syndrome of ORTHOSTATIC INTOLERANCE combined with excessive upright TACHYCARDIA, and usually without associated ORTHOSTATIC HYPOTENSION. All variants have in common an excessively reduced venous return to the heart (central HYPOVOLEMIA) while upright.
Symptoms of cerebral hypoperfusion or autonomic overaction which develop while the subject is standing, but are relieved on recumbency. Types of this include NEUROCARDIOGENIC SYNCOPE; POSTURAL ORTHOSTATIC TACHYCARDIA SYNDROME; and neurogenic ORTHOSTATIC HYPOTENSION.

Adverse drug effects associated with CHOLINERGIC ANTAGONISTS. Clinical features include TACHYCARDIA; HYPERTHERMIA; MYDRIASIS, dry skin and dry mucous membranes, decreased bowel sounds and urinary retention in peripheral anticholinergic syndrome; and HALLUCINATIONS; PSYCHOSES; SEIZURES; and COMA in central anticholinergic syndrome.
A malignant form of polymorphic ventricular tachycardia that is characterized by HEART RATE between 200 and 250 beats per minute, and QRS complexes with changing amplitude and twisting of the points. The term also describes the syndrome of tachycardia with prolonged ventricular repolarization, long QT intervals exceeding 500 milliseconds or BRADYCARDIA. Torsades de pointes may be self-limited or may progress to VENTRICULAR FIBRILLATION.
A generic expression for any tachycardia that originates above the BUNDLE OF HIS.
