Recurrent Postural Vasovagal Syncope
Background—The pathophysiology of vasovagal syncope is poorly understood, and the treatment usually ineffective. Our clinical experience is that patients with vasovagal syncope fall into 2 groups, based on their supine systolic blood pressure, which is either normal ( 100 mm Hg) or low (70–100 mm Hg). We investigated neural circulatory control in these 2 phenotypes. Methods and Results—Sympathe...

متن کاملOrthostatic intolerance: postural orthostatic tachycardia syndrome with overlapping vasovagal syncope.
A 28-year-old female with a history of situational syncope and a new-onset right sided hemiparesis is described. Tilt-up table test revealed the postural orthostatic tachycardia syndrome followed by vasovagal syncope. Neurological and internal medicine tests showed no particular disorders. The patient underwent autonomic physical training and the tilt-up test performed three months later showed...
متن کاملRelation of postural vasovagal syncope to splanchnic hypervolemia in adolescents.
BACKGROUND The mechanisms of simple faint remain elusive. We propose that postural fainting is related to excessive thoracic hypovolemia and splanchnic hypervolemia during orthostasis compared with healthy subjects. METHODS AND RESULTS We studied 34 patients 12 to 22 years old referred for multiple episodes of postural faint and 11 healthy subjects. Subjects were studied in the supine positio...
