Vasovagal syncope is a common cause of sudden collapse. It results from inappropriate activation of left ventricular mechanoreceptors causing sudden vasodilation with bradycardia. Tilt testing is an inexpensive and non-invasive way of establishing a vasovagal diagnosis in unexplained syncope.

An imbalance between the sympathetic and parasympathetic nervous systems has been indicated in obesity. The aim of the present study was to evaluate the results of tilt table testing (TT) in obese patients.59 patients with simple obesity (F/M: 50/9; BMI: 36.9+/-3.9 kg/m(2)), and 19 healthy subjects of the control group (F/M: 16/3; BMI: 24.7+/-4.3 kg/m ...

Evaluation of the “Tilt Test” in children
Annals of Emergency Medicine, 1987The "tilt test" (assessment of orthostatic pulse and blood pressure) is a non-invasive screening test for acute intravascular volume loss with well-accepted utility in the emergency evaluation of adults. Its value in children has been questioned because of reports of high false-positive rates.

Pathophysiological studies of tilt table aided orthostatic stress on humans were fifty years old before the evolution of head-upright tilt table testing into the diagnostic test of choice in vasovagal syncope. Variations in orthostatic tolerance demonstrated by tilt table testing were observed in normal subjects1,2 and in association with pregnancy,3 ...

The contribution of isoproterenol to the prolonged tilt test
International Journal of Cardiology, 1995In this study the tilt test, in combination with isoproterenol administration, was used to investigate 44 patients with unexplained syncope. The reproducibility of the method was studied in a group of 32 patients who underwent a second test. The administration of isoproterenol during the test increased the sensitivity of the method from 52 to 70% and ...

Tilt table testing for syncope and collapse
Herzschrittmachertherapie + Elektrophysiologie, 2018Head-up tilt (HUT) has long been used to examine heart rate and blood pressure adaptation to changes in position. During such studies, incidental observations noted that some test subjects experienced total or near-total transient loss of consciousness and that, in some cases, hypotension was associated with unexpected marked bradycardia compatible ...

Bielschowsky head-tilt test—II. Quantitative mechanics of the Bielschowsky head-tilt test
Vision Research, 1985In ten recent cases of superior oblique (SO) palsy the involved eye elevated by 8.2 +/- 3.8 deg (standard deviation) on 45 deg ipsilateral head tilt. A computer model predicted a rise to only 4.1 deg but could easily achieve 8.2 deg by including reactions in the other cyclovertical muscles, notably on overaction of the superior rectus (SR).

Phase-tilting interferometry for optical testing
Optics Letters, 2013Phase-tilting interferometry for optical testing is proposed to retrieve the phase from interferograms with random phase tilts. The Radon transform is used to extract the tilted phase plane, and the phase distribution is retrieved by the least squares method.
