Vasovagal oscillations and vasovagal responses produced by the Vestibulo-Sympathetic Reflex in the rat

Frontiers in Neurology, 2014
Sinusoidal galvanic vestibular stimulation (sGVS) induces oscillations in blood pressure (BP) and heart rate (HR) i.e., vasovagal oscillations, and decreases in BP and HR i.e., vasovagal responses, in isoflurane-anesthetized rats.

Long QT Syndrome Type 5 With Coexisting KCNE1 and RYR2 Variants: A Diagnostic Ambiguity

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Long QT syndrome (LQTS) predisposes to syncope and sudden cardiac death. Type 5 LQTS, linked to KCNE1 variants, is rare. A teenage female presented with recurrent syncope. ECG showed QTc 485 ms. Genetic testing identified KCNE1 and RYR2 variants. Beta‐blockers and ICD prevented events.

How to Prevent Recurrence of Idiopathic Lead Migration: A Case Report and Discussion of Management

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Reverse ratchet syndrome is an extremely rare form of idiopathic lead migration. Firm fixation of the lead sleeve to the fascia is crucial to prevent recurrence; however, even with reinforced fixation, muscle motion or intrinsic sleeve design may limit the ability to prevent idiopathic lead migration.

Tilt Test as a Primary Non-Invasive Method for Testing Cardiac Autonomic Nervous System Function in Patients with Vasovagal Syncope

Український журнал серцево-судинної хірургії
Introduction Syncope is a sudden, brief loss of consciousness with rapid spontaneous recovery, caused by transient global cerebral hypoperfusion. Among various causes of syncope, the most common are reflex mechanisms, particularly vasovagal syncope ...

Original paper
Heart rate variability in patients with recurrent syncope

Archives of Medical Science, 2006
Introduction: The autonomic nervous system participates in the pathophysiology of vasovagal syncope. The disturbances in the autonomic nervous system can be measured by heart rate variability (HRV).

Brugada Syndrome: New Implications for Heterozygous Carriers of the Pathogenic SCN5A c.689T>C(p.Ile230Thr) Variant

American Journal of Medical Genetics Part A, Volume 200, Issue 5, Page 1083-1086, May 2026.
ABSTRACT Pathogenic variants in the SCN5A gene and its subunits have been identified in individuals with Brugada Syndrome. One such SCN5A variant, c.689T>C(p.Ile230Thr), was previously reported as disease‐causing only in homozygous individuals, with heterozygous carriers being unaffected.

Adenosine: Potential modulator for vasovagal syncope

, 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.

Video education to improve clinical skills in the prevention of and response to vasovagal syncopal episodes

International Journal of Women's Dermatology, 2020
Background: Vasovagal syncope is a common clinical occurrence during routine outpatient dermatology procedures, such as injections and biopsies. Despite its prevalence, many medical students and health care professionals do not know how to respond ...
