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 کاملHead-up tilt test in complicated neurocardiogenic syncope in children.
To confirm the usefulness of head-up tilt test (HUT) in neurocardiogenic syncope (NCS) with complicating clinical features, retrospective analysis were done on 12 selected children. The age at onset was 12.7 +/- 1.9 (mean +/- SD) years. Associated clinical features were postoperative congenital heart disease (PO CHD) in 3, coexistent arrhythmia in 8 (persistent ventricular arrhythmia during exe...
متن کاملHead-up tilt test for recurrent syncope in pilots.
Syncope is defined as a sudden temporary loss of consciousness and postural tone that is associated with spontaneous recovery. Vasovagal or neurocardiogenic syncope is a common and usually benign cause of syncope. The mechanism may be cardioinhibitory, vasodepressor, or both. Diagnosis is usually made by a typical patient history with a definite trigger. Although vasovagal syncope is considered...
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 ...

the supine position for 10 minutes. The test consisted of 2 Introduction The head-up tilt test (HUTT) is a useful diagnostic tool for evaluating suspected neurocardiogenic syncope. Pharmacologic provocation with isoproterenol, adenosine, or nitroglycerin (NTG) is frequently used to facilitate the induction of syncope during HUTT. Studies have reported the occurrence of ventricular arrhythmias d...
