Tilt Table Test: State of The Art

Indian Pacing and Electrophysiology Journal, 2003
The loss of consciousness has been a subject of wonder and uncertainty in humans, and for this reason it has been the object of medical investigation since the beginning of time. Even actually, it is certainly an unresolved clinical problem.

Classical and Delayed Orthostatic Hypotension in Patients With Unexplained Syncope and Severe Orthostatic Intolerance

Frontiers in Cardiovascular Medicine, 2020
Background: Orthostatic hypotension (OH) is a major sign of cardiovascular autonomic failure leading to orthostatic intolerance and syncope. Orthostatic hypotension is traditionally divided into classical OH (cOH) and delayed OH (dOH), but the ...

Galactic kinematics with modified Newtonian dynamics

, 2009
We look for observational signatures that could discriminate between Newtonian and modified Newtonian (MOND) dynamics in the Milky Way, in view of the advent of large astrometric and spectroscopic surveys.

Octahedral coupling in (111)- and (001)-oriented La$_{2/3}$Sr$_{1/3}$MnO$_3$/SrTiO$_3$ heterostructures

, 2018
Rotations and distortions of oxygen octahedra in perovskites play a key role in determining their functional properties. Here we investigate how octahedral rotations can couple from one material to another in La$_{2/3}$Sr$_{1/3}$MnO$_3$/SrTiO$_3 ...

Age-related cardiovascular response to tilt test in healthy volunteers of both sexes

Bangabandhu Sheikh Mujib Medical University Journal, 2020
This study aimed to assess the age-related changes in the cardiovascular response to tilt test in 90 healthy individuals of both sexes (age range: 18-60 years). Tilting was done at 600 for 10 min using a motorized tilt table.
