متن کاملSeizure-Like Activities during Head-Up Tilt Test-Induced Syncope
PURPOSE Some patients with neurally mediated reflex syncope may be misdiagnosed as epilepsy because myoclonic jerky movements are observed during syncope. The seizure-like activities during the head-up tilt test (HUT) have been rarely reported. The purpose of this study was to assess the characteristics of these seizure-like activities and evaluate whether there are differences in the clinical ...
متن کاملLeg intravenous pressure during head-up tilt.
Leg vascular resistance is calculated as the arterial-venous pressure gradient divided by blood flow. During orthostatic challenges it is assumed that the hydrostatic pressure contributes equally to leg arterial, as well as to leg venous pressure. Because of venous valves, one may question whether, during orthostatic challenges, a continuous hydrostatic column is formed and if leg venous pressu...
متن کاملLow body mass index is associated with a positive response during a head-up tilt test.
BACKGROUND To describe the association between body mass index (BMI) and a positive response during a head-up tilt test (HUT) in patients referred for an investigation of syncope. METHODS Observational study of patients referred for the diagnostic evaluation of syncope. Patients were divided into four groups according to their BMI: <18.5 kg/m(2), 18.5-24.9 kg/m(2), 25-29.9 kg/m(2), and > 30 k...
متن کاملDiagnostic relevance of the carotid sinus massage during a head up tilt table test (HUTT).
BACKGROUND Syncope due to carotid sinus hypersensitivity (CSH) may be underdiagnosed due to a low level of diagnostic suspicion and fear of complications caused by massage of the carotid sinus. OBJECTIVE To investigate the relevance of carotid sinus massage in the diagnosis of non-convulsive faints and unexplained falls. METHODS Two-hundred and fifty-nine patients with a mean age of 50+/-24...
