Short-duration head-up tilt test potentiated with sublingual nitroglycerin in suspected vasovagal syncope: the fast Italian protocol.

European Heart Journal, 2023
BACKGROUND The traditional nitroglycerin (NTG) head-up tilt test (HUTT) is time-consuming and the test duration is a barrier to widespread utilization in clinical practice.

Tilt Test: A Review

Journal of clinical neurophysiology, 2021
Summary: This review recapitulates the head-up tilt test, which is commonly used for evaluation of orthostatic syndromes and dysautonomia. Tilt test evaluates autonomic system responses to orthostatic stress.

Age-related tilt test responses in patients with suspected reflex syncope.

Europace, 2021
AIMS Tilt testing (TT) is recognized to be a valuable contribution to the diagnosis and the pathophysiology of vasovagal syncope (VVS). This study aimed to assess the influence of age on TT responses by examination of a large patient cohort.

Experimental Studies on the Basic Friction Angle of Planar Rock Surfaces by Tilt Test

Journal of Testing and Evaluation, 2018
The basic friction angle is a basic parameter for estimating the shear strength of rock discontinuities. The value of the basic friction angle can be determined using the tilt test. There are still no standard methods for such a test.

Experimental Study of Factors Controlling Tilt-Test Results Performed on Saw-Cut Rock Joints

Geotechnical Testing Journal, 2018
One of the main inputs when estimating the shear strength of rock discontinuities, according to most existing strength criteria, is what is known as the basic friction angle, which is a parameter that responds to the frictional resistance of a planar ...
