Heart rate variability analysis during head-up tilt test predicts nitroglycerine-induced syncope
OBJECTIVE The aim of this study was to determine whether or not heart rate variability (HRV) analysis during the first 20 min of head-up tilt testing could predict whether patients will develop syncope after nitroglycerine administration. DESIGN 64 patients with previous loss of consciousness underwent head-up tilt testing with the Italian protocol, which involves the administration of nitrog...
متن کاملProvocation of neurocardiogenic syncope by clomipramine administration during the head-up tilt test in vasovagal syndrome.
OBJECTIVES We sought to test the hypothesis that activation of the serotonergic system in patients with vasovagal syndrome during the head-up tilt test provokes syncope. BACKGROUND Central serotonergic activation participates in the pathogenesis of neurocardiogenic syncope. Drugs increasing serotonin (5-HT) in the central nervous system have not been tested as drug challenges during the head-...
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 کامل[Head-up tilt test in vasovagal syncope: for which purposes? for whom?].
30 Vasovagal syncope is a disorder that has been known for years since its clinical characteristics were masterfully described by Sir Thomas Lewis at the beginning of the 20th century.1 Traditionally, the criteria used to establish the diagnosis of a vasovagal origin in patients with syncopal episodes was based only on the presence of triggering circumstances and typical prodromic symptoms. In ...
متن کاملCerebral autoregulatory responses to head-up tilt in normal subjects and patients with recurrent vasovagal syncope.
BACKGROUND The effect of orthostatic stress on dynamic cerebral autoregulation (CA) in normal subjects and patients with recurrent vasovagal syncope (VVS) is unclear. This study assessed the dynamic CA responses of both groups to head-up tilt. METHODS AND RESULTS Seventeen patients with recurrent VVS and 17 pair-matched control subjects underwent 70 degrees head-up tilt for up to 30 minutes. ...
