Prediction of Head-Up Tilt Test Result: Is it Possible?

Pacing and Clinical Electrophysiology, 2010
The determination of early, accurate, predictive criteria for a positive result would permit a reduction in the duration of the head-up tilt testing (HUTT). Previous studies propounded that existence of early sympathetic overreactivity (rapid and sustained increase in heart rate) during HUTT predicts positive result.

Relevance of asystole during head-up tilt testing

The American Journal of Cardiology, 1995
The prognosis of patients manifesting prolonged asystole during head-up tilt testing is unclear. In 209 consecutive patients with a history of syncope and positive head-up tilt tests, 19 had asystole lasting > 5 seconds (mean duration 15 +/- 10) (group 1a).

Effect of passive tilting duration on the outcome of head-up tilt testing

Acta Cardiologica, 2007
We sought to compare the results of head-up tilt test (HUT) using the most common protocols, namely the Italian and Westminster prolonged by nitroglycerin (modified Westminster) protocols. We also investigated the role of passive tilting duration on HUT outcome.From 478 syncopal patients 306 (64%) individuals showed positive tilting results (HUT ...

Prolonged asystole provoked by head-up tilt testing

Clinical Research in Cardiology, 2006
We describe a patient with a history of neurocardiogenic syncopes who had a positive headup tilt test that resulted in an lasting asystole lasting 34 seconds. However, the previously carried out Schellong test with a 30-min phase of standing showed a normal result. The patient showed typical orthostatic symptoms while tilted at the angle of 75 degrees.

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].

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 ...

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).

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,

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
