The contribution of isoproterenol to the prolonged tilt test

International Journal of Cardiology, 1995
In 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 ...

Phase-tilting interferometry for optical testing

Optics Letters, 2013
Phase-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.

Bielschowsky head-tilt test—II. Quantitative mechanics of the Bielschowsky head-tilt test

Vision Research, 1985
In 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). In 17 older

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 ...

Tilt Table Testing

2016
Tilt table testing (TTT) was introduced about two decades ago for the evaluation of patients with unexplained syncope. Initially, it was welcome and spread enthusiastically through different medical specialties, but its use has decreased due to the recognition of several limitations when inappropriately employed.

The Active Stand and Tilt Tests

2020
A critical step in the clinical evaluation of postural tachycardia syndrome (PoTS) is the assessment of orthostatic tachycardia. Active stand testing (AST) and head up tilt table testing (HUT) can both be used to evaluate the presence of this tachycardia.

Evaluation of the Bielschowsky Head-Tilt Test

Archives of Ophthalmology, 1969
Tilting of the head as an aid in diagnosis of paretic vertical muscles is based on the theory that torsional action of the vertical muscles maintains the vertical meridians of the eyes erect when the head is tilted to the side. Since rotation of the optic disc about the macula occurs in the same direction, approximately to the same degree as the head ...
