Head-up Tilt Test

Circulation, 1997
Background Patients with bifascicular block have an increased risk of syncopal attacks, but the underlying mechanism often remains unclear despite an extensive diagnostic workup. The head-up tilt test has been established as an important diagnostic tool in the unmasking of vasovagal syncope in patients with unexplained syncope.

Head-Up Tilt Testing for Neurocardiogenic Syncope

Cardiac Electrophysiology Review, 2000
Head-up tilt testing has been used to identify patients with syncope in whom hypotension with bradycardia is likely to develop [1]. The term “neurocardiogenic syncope” [2] is used to describe this abnormal response, previously termed vasovagal by Lewis [3].

Response to head-up tilt testing in patients with situational syncope

The American Journal of Cardiology, 1998
The results of head-up tilt testing were compared between 24 patients with situational syncope and 44 age-matched patients with typical vasovagal syncope. Patients with situational syncope showed poor positive responses, especially in the passive tilt results (8.3% vs. 39%, p = 0.0078).

Psychogenic syncope diagnosed by prolonged head-up tilt testing

QJM: An International Journal of Medicine, 1995
Abstract Four patients with ‘syncope’ during prolonged headup tilt testing despite normal blood pressure and heart-rate behaviour are described. They represent 5.5% of all positive tilt-test outcomes from a prospective study of 181 consecutive patients with unexplained syncope.

Head-up tilt test diagnostic yield in syncope diagnosis

Journal of Electrocardiology, 2020
The European Syncope Guidelines (ESG) recommend the use of Head-up tilt test (HUT) in case of suspicion of vasovagal syncope (VVS) or orthostatic hypotensive syncope (OHS) after an adequate initial inconclusive evaluation. We report a single center experience in the scenario of suspected VVS or OHS, who underwent HUT in patients referred to a Syncope ...

Transient aphasia: a rare complication of head-up tilt test

Neurological Sciences, 2014
Head-up tilt test (HUT) is widely used as a diagnostic tool. It reproduces vasovagal attacks in many susceptible patients. Although it is known to be safe and well tolerated, it is a procedure with potential neurologic complications. We observed that it could cause transient aphasia in some patients.

Head-up Tilt Table Testing: A state-of-the-art review

Minerva medica, 2009
Vasovagal syncope (VVS) is the commonest cause of syncope accounting for up to 60% of all cases. The head-up tilt-table test (HUTT) was first described as a diagnostic test for VVS in 1986 and is now in widespread use as a research and diagnostic tool. Vasovagal syncope was previously thought to be confined to younger patients but with the introduction

[Head-up tilt test].

Journal of cardiology, 2000
Head-upright tilt table testing has been used as a research tool over the past 50 years by physiologists and/or physicians to study the hemodynamic and endocrine adaptation to changes in position. Tilt test has become a widely accepted tool in the clinical evaluation of patients with syncope, since its first application to patients with syncope by ...

Syncope: The Diagnostic Value of Head‐Up Tilt Testing

Pacing and Clinical Electrophysiology, 1997
To determine the usefulness of prolonged head‐up tilt in the diagnosis of neurally mediated syncope, 201 patients with history of syncope of unknown cause and 102 age and gender matched control subjects underwent a 40 minute 60 degree head‐up tilt test. Head‐up tilt elicited syncope (i.e., was positive) in 74 of the 201 patients (37%) with a history of

Cardiovascular and renin responses to head-up tilt tests in parkinsonism

Acta Neurologica Scandinavica, 2009
We investigated cardiovascular and renin responses to head-up tilt tests in patients with Parkinson's disease (PD), multiple system atrophy (MSA), and in controls to determine variables for the assignment of parkinsonism to the potential underlying neurologic condition.Sequential changes in sympathetic-mediated circulatory variables such as heart rate,
