Comparison of a 20 degree and 70 degree tilt test in adolescent myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) patients [PDF]

open access: yesFrontiers in Pediatrics, 2023
IntroductionDuring a standard 70-degree head-up tilt test, 90% of adults with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) develop an abnormal reduction in cerebral blood flow (CBF).

A Tick of the Clock: Finding the Sweet Spot in Tilt Table Test. The Effectiveness of Short‐Duration Head‐Up Tilt Test as a Diagnostic Tool in Suspected Vasovagal Patients: A Retrospective Observational Study in a Tertiary Syncope Unit [PDF]

open access: yesJournal of Arrhythmia
Aims The head‐up tilt test (HUTT) has been markedly changed over the years, especially in the specified time for the passive and active phases. However, a consensus‐based protocol has yet to be established.

Entropy Measures in the Assessment of Heart Rate Variability in Patients with Cardiodepressive Vasovagal Syncope

open access: yesEntropy, 2015
Sample entropy (SampEn) was reported to be useful in the assessment of the complexity of heart rate dynamics. Permutation entropy (PermEn) is a new measure based on the concept of order and was previously shown to be accurate for short, non-stationary ...
