Management of Postural Tachycardia Syndrome, Inappropriate Sinus Tachycardia and Vasovagal Syncope [PDF]

Arrhythmia & Electrophysiology Review, 2016
Postural tachycardia syndrome (POTS), inappropriate sinus tachycardia (IST) and vasovagal syncope (VVS) are relatively common clinical syndromes that are seen by physicians in several disciplines. They are often not well recognised and are poorly understood by physicians, are associated with significant morbidity and cause significant frustration for ...

Time‐Resolved Multi‐Omics Identify Biomarkers of Immediate Reactions to mRNA Vaccination

Allergy, EarlyView.
We compared early vaccine‐induced immune and metabolic signatures and downstream immunity after second and booster BNT162b2 doses in participants with sARs, ISSRs, or no reactions. Neutrophil mobilization, antiviral programs, and robust anti‐S‐antibody responses occurred across reaction groups.

Adenosine: Potential modulator for vasovagal syncope [PDF]

, 1996
Objectives. This study examined the hypothesis that adenosine could provoke a vasovagal response in susceptible patients. Mechanisms of the vasovagal response were further explored by studying the adenosine-mediated reactions.Background.

Tilt Table Testing in Paediatric Orthostatic Intolerance: Is 10 Min Long Enough?

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Aim Recent cardiovascular literature suggests that orthostatic testing protocols should be tailored according to diagnostic purpose, distinguishing syncope evaluation from assessment of autonomic dysfunction in chronic orthostatic intolerance (COI).

Validation of the TruBlue Light Laser for Laryngeal Somatosensory and Perturbation Testing

The Laryngoscope, Volume 136, Issue 9, Page 3841-3848, September 2026.
This study validates a blue light laser method for assessing laryngeal somatosensory function by measuring perceptual thresholds, reflexive responses, discrimination acuity, and vocal perturbations in healthy adults. Results demonstrate that the method provides precise, reliable stimulation and yields quantifiable sensory and acoustic responses ...
