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.

Vasovagal Syncope in the Older Patient

Journal of the American College of Cardiology, 2008
Vasovagal syncope (VVS) has been diagnosed with increasing frequency in older patients since the head-up tilt-table test (HUT) was described over 2 decades ago. The incidence and prevalence of VVS in this age group remains unknown. Older individuals are more likely to display a dysautonomic hemodynamic pattern with a predominantly hypotensive response ...

Vasovagal syncope interrupting sleep? [PDF]

Heart, 2004
Clinical data are reported for 13 patients who were referred with recurrent loss of consciousness at night interrupting their sleep. Most of the patients were women (10 of 13) with a mean age of 45 years (range 21-72 years). The histories were more consistent with vasovagal syncope than with epilepsy.

Minimizing Atrioesophageal Fistula Risk After AF Ablation: Risk Factors, Prevention, and Emerging Mini‐Thermal Technology

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Atrial esophageal fistula (AEF) is a rare but life‐threatening complication of atrial fibrillation (AF) ablation, linked to thermal injuries by conventional radiofrequency (RF) and cryo‐balloon (CB) ablation techniques. AEF risk can be mitigated by considering several measures such as tailored power settings of ablation technique, mechanical ...

Structural heart disease as the cause of syncope

Brazilian Journal of Medical and Biological Research, 2018
We described the clinical evolution of patients with structural heart disease presenting at the emergency room with syncope. Patients were stratified according to their syncope etiology and available scores for syncope prognostication.

Twenty-Four-Hour Urinary Sodium Excretion Predicts Therapeutic Effectiveness of Oral Rehydration Saline in Pediatric Vasovagal Syncope

Children, 2022
The study was designed to explore whether 24-hour urinary sodium excretion could predict the therapeutic effectiveness of oral rehydration saline in pediatric cases of vasovagal syncope.

Vascular health and exercise in females throughout the lifespan: Exploring puberty, pregnancy and menopause

Experimental Physiology, EarlyView.
Abstract This narrative review highlights the impact of exercise on vascular health in females over the lifespan with an emphasis on puberty, pregnancy and menopause. These events encompass substantial changes in sex hormone levels, particularly oestrogens and progesterone.

Novel Methods for Quantification of Vasodepression and Cardioinhibition During Tilt-Induced Vasovagal Syncope

Circulation Research, 2020
Supplemental Digital Content is available in the text. Rationale: Assessing the relative contributions of cardioinhibition and vasodepression to the blood pressure (BP) decrease in tilt-induced vasovagal syncope requires methods that reflect BP ...

Endothelial function in vasovagal syncope [PDF]

Expert Review of Cardiovascular Therapy, 2014
Vasovagal syncope (VVS) is a common form of fainting. The pathophysiology of VVS is complex and involves changes in the autonomic and vascular tone, resulting in reflex bradycardia with marked hypotension. Paradoxical peripheral vasodilation caused by endothelial dysfunction may also play a key role in inappropriate hypotension during VVS.
