Syncope is a common problem in children and adolescents. It is typically caused by benign neurally mediated hypotension, but other, more concerning, etiologies of syncope must be considered. In most c...
Neurally mediated reflex syncope is the most common cause of syncope in young individuals without cardiac or neurological pathology. We report a case of successful catheter ablation in a 17-year-old m...
To explore the circadian rhythm of neurally mediated syncope (NMS).
Recent evidences have supported migraine headache and neurally mediated syncope as the especial types of endotheliopathies. To determine endothelial function in patients with migraine headache or thos...
Gastrointestinal symptoms of nausea, vomiting and abdominal pain are common in patients with orthostatic intolerance (OI), including neurally mediated hypotension (NMH) and postural orthostatic tachyc...
ISSUE 3 is a multi-center, prospective, randomised controlled double-blind study aimed to assess the effectiveness of pacemaker therapy for prevention of asystolic neurally-mediated synco...
This multiple-center, randomized, 2 part, single- and double-blind study will be conducted in male and female subjects with neurogenic orthostatic hypotension to evaluate the effect of TD-...
The purpose of this study is to determine whether Fipamezole is effective in the treatment of orthostatic hypotension and related symptoms in multiple system atrophy and Parkinson's diseas...
The aim of the study is to evaluate whether orthostatic hypotension is associated with nondipping hypertension. Methods and patients: 400 subjects who are referred for 24hABPM will be fil...
OBJECTIVES: I. Study further the safety and efficacy of the alpha-receptor agonist midodrine in patients with neurogenic orthostatic hypotension. II. Assess the quality of life in these...
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. (From Noseworthy, JH., Neurological Therapeutics Principles and Practice, 2007, p2575-2576)
A significant drop in BLOOD PRESSURE after assuming a standing position. Orthostatic hypotension is a finding, and defined as a 20-mm Hg decrease in systolic pressure or a 10-mm Hg decrease in diastolic pressure 3 minutes after the person has risen from supine to standing. Symptoms generally include DIZZINESS, blurred vision, and SYNCOPE.
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.
An autosomal disorder of the peripheral and autonomic nervous systems limited to individuals of Ashkenazic Jewish descent. Clinical manifestations are present at birth and include diminished lacrimation, defective thermoregulation, orthostatic hypotension (HYPOTENSION, ORTHOSTATIC), fixed pupils, excessive SWEATING, loss of pain and temperature sensation, and absent reflexes. Pathologic features include reduced numbers of small diameter peripheral nerve fibers and autonomic ganglion neurons.

A degenerative disease of the AUTONOMIC NERVOUS SYSTEM that is characterized by idiopathic ORTHOSTATIC HYPOTENSION and a greatly reduced level of CATECHOLAMINES. No other neurological deficits are present.
