Comparison of short head-up tilt test with conventional protocol after omission of nonmedicated phase in children and young adults

Advanced Biomedical Research, 2016
Background: Syncope is an important and common clinical condition, and the neurally mediated syncope is the most frequent type of syncope. Tilt testing is considered as a first-line diagnostic test.

On the feasibility of tilt test outcome early prediction using ECG and pressure parameters

EURASIP Journal on Advances in Signal Processing, 2011
The tilt test is a valuable clinical tool for vasovagal syncope (VVS) diagnostic, and its early prediction from simple ECG and blood pressure-based parameters has widely been studied in the literature.

Simultaneous beat-to-beat heart rate and systolic blood pressure variability in patients with and without neurally mediated syncope [PDF]

Journal of Cardiovascular and Thoracic Research, 2022
Introduction: Autonomic changes play an essential role in the genesis of neurally mediated syncope (NMS). The aim of this study was to compare the changes of the autonomic nervous system (ANS) by measuring spectral indices of beat-to-beat systolic blood ...
