Does a Role Exist for Tilting-Guided Therapy in the Management of Neurocardiogenic Syncope?

Arquivos Brasileiros de Cardiologia, 2002
PURPOSE: Upright tilt-table testing (UTT) is an useful method for identifying patients with neurocardiogenic syncope, but its role in the evaluation of therapeutic efficacy is controversial.

POLYMORPHISMS IN β-ADRENERGIC RECEPTORS ARE ASSOCIATED WITH INCREASED RISK TO HAVE A POSITIVE HEAD-UP TILT TABLE TEST IN PATIENTS WITH VASOVAGAL SYNCOPE.

Revista de investigacion clinica; organo del Hospital de Enfermedades de la Nutricion, 2019
Background Vasovagal syncope (VVS) is a frequent clinical condition in which a genetic background seems to be implicated. Considering that the adrenergic receptors (ARs) may play a role in VVS, the present study has as principal aim to determine if the α-

Recommendations for tilt table testing and other provocative cardiovascular autonomic tests in conditions that may cause transient loss of consciousness

Clinical Autonomic Research, 2021
An expert committee was formed to reach consensus on the use of tilt table testing (TTT) in the diagnosis of disorders that may cause transient loss of consciousness (TLOC) and to outline when other provocative cardiovascular autonomic tests are needed ...

Variation in pelvic morphology may prevent the identification of anterior pelvic tilt [PDF]

, 2008
Pelvic tilt is often quantified using the angle between the horizontal and a line connecting the anterior superior iliac spine (ASIS) and the posterior superior iliac spine (PSIS).

Feasibility of Blood Pressure Measurement With a Wearable (Watch‐Type) Monitor During Impending Syncopal Episodes

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background We assessed the reliability and feasibility of blood pressure (BP) measurements by means of a new wearable watch‐type BP monitor (HeartGuide) in detecting episodes of hypotensive (pre)syncope induced by tilt table test.

Low Sensitivity of Abbreviated Tilt Table Testing for Diagnosing Postural Tachycardia Syndrome in Adults With ME/CFS

Frontiers in Pediatrics, 2018
Introduction: Orthostatic intolerance is common among individuals with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). In some ME/CFS case definitions, orthostatic intolerance is considered a core feature of the disorder.

Assessment of Quadratic Nonlinear Cardiorespiratory Couplings During Tilt-Table Test by Means of Real Wavelet Biphase

IEEE Transactions on Biomedical Engineering, 2017
Objective: In this paper, a method for assessment of quadratic phase coupling (QPC) between respiration and heart rate variability (HRV) is presented. Methods: First, a method for QPC detection is proposed named real wavelet biphase (RWB). Then, a method

Design study of time-preserving grating monochromators for ultrashort pulses in the extreme-ultraviolet and soft X-rays [PDF]

, 2017
The design of grating-based instruments to handle and condition coherent ultrafast pulses in the extreme-ultraviolet is discussed. The main application of such instruments is the monochromatization of high-order laser harmonics and free-electron-laser ...

Optimal design of photovoltaic shading systems for multi-story buildings [PDF]

, 2019
This study provides new insights into the comprehensive energy and economic performances of photovoltaic shading systems (PVSS) in multi-story buildings. A numerical shading model was developed to evaluate the shading effect from an upper PVSS row on its
