This study assesses the vasovagal collapse pattern changes, ie, heart rate (HR) and arterial
blood pressure (BP) with a 2-stage tilt-test protocol using glyceryl trinitrate (GTN) …

Head-up tilt testing (HUTT) potentiated with sublingual nitroglycerin has gained acceptance
as means of diagnosing neurally mediated syncope. To evaluate the reproducibility of HUTT …

Objectives: We sought to determine whether there are age-related differences in vasovagal
syncope. Background: In those with suspected vasovagal (neurocardiogenic) syncope, tilt …

Shortened head-up tilt testing (HUT) potentiated with sublingual nitroglycerin (60° passive
standing for 20 minutes followed, if negative, by 400 μg of sublingual nitroglycerin spray with …

Aims To compare the sensitivity, specificity and adverse event profile of glyceryl trinitrate
head-up tilt with isoprenaline head-up tilt in the diagnosis of vasovagal syncope in patients …

Background: Head-up tilt testing is widely used in the clinical assessment of patients with
unexplained syncope. However, the lack of a standard methodology and the conflicting …

This study was undertaken to assess the value of sublingual nitroglycerin administration
during upright tilt as a simple practical test for the diagnosis of vasovagal syncope. To this …

Background Head-up tilt testing is extensively used to determine the vasovagal origin of
syncope in patients with otherwise unexplained loss of consciousness, although issues …

Aims During head-up tilt (HUT) testing, a period of haemodynamic instability, marked by
oscillations in blood pressure, often precedes vasovagal syncope. We hypothesized that the …

OBJECTIVE: Nitrate-stimulated tilt testing may be used to diagnose vasovagal syncope or to
guide therapy. To date, the reproducibility of the test in patients with clinically suspected …
