Reproducibility of the Adenosine-5′-Triphosphate Test in Vasovagal Syndrome
Journal of Cardiovascular Electrophysiology, 1998Vasovagal Syndrome: ATP Test Reproducibility. Introduction: Adenosine‐5′‐triphosphate (ATP) provokes negative chronotropic and dromotropic vagal effects. In vasovagal syndrome, ATP test (20‐mg IV bolus infusion) represents a promising technique for identifying patients at risk of severe cardioinhibitory response of vagal origin.

Most cases of dizziness or syncope referred to the emergency department or to services of internal medicine are caused by vasovagal syndromes. They comprise relative bradycardia with vasoplegia, the cardiovascular response to a neurological stimulus.

PACE - Pacing and Clinical Electrophysiology, 1994
Eleven subjects (mean age 50 years, range 33–71 years), who had previously received permanent dual chamber pacemakers for cardioinhibitory vasovagal syncope, underwent paired Westminster protocol tilt tests, one with short AV delay VDD pacing and one without pacing, to test the hypothesis that continuous ventricular pacing would prevent the cardiac ...

Revue d'odonto-stomatologie, 1992
The vaso-vagal syndrome, the most frequent accident may appear during dental treatments, can involve breve conscience loss. In case of important bradycardia, the medical treatment consists in an intravenous injection of atropine sulfate. Prevention of this syndrome consists in an anxiolytic and/or vagolytic premedication.

Update on the Role of Pacemaker Therapy in Vasovagal Syncope and Carotid Sinus Syndrome
Progress in Cardiovascular Diseases, 2013Vasovagal syncope (VVS) and carotid sinus syndrome (CSS) are related, neurally mediated disorders with different clinical features and treatment implications. Pacemaker intervention studies in both syndromes are hampered by a dearth of randomized, controlled (particularly with placebo) studies, unfortunate premature termination of studies, and ...

Differential Diagnosis of Vasovagal Syncope: Sick Sinus Syndrome
2014Sick sinus syndrome (SSS) can be diagnosed only when there is a clear correlation between symptoms and sinus node (SN) dysfunction. In the absence of such correlation, the mechanism of undocumented intermittent symptoms such as syncopal spells in patients with permanent mild sinus bradycardia remains uncertain.

Arrhythmic Storm Responsive to Quinidine in a Patient with Brugada Syndrome and Vasovagal Syncope
Pacing and Clinical Electrophysiology, 2005A 37‐year‐old man with Brugada syndrome (BrS) and arrhythmic storm is described. One month after implantation of a cardioverter‐defibrillator he presented with recurrent appropriate shocks for spontaneous ventricular fibrillation (VF). Because of this arrhythmic storm, quinidine therapy was initiated with total suppression of all spontaneous ...

Head-upright tilt-table testing in evaluation and management of the malignant vasovagal syndrome
The American Journal of Cardiology, 1992Vasovagally mediated cardiac asystole has been proposed as a potential cause of sudden cardiac death. To assess this possibility and identify characteristics that define patients with vasovagally mediated asystole, head-upright tilt-table testing was performed in 50 consecutive patients (26 women and 24 men, mean age 42 +/- 10 years) with recurrent ...

Can Adenosine 5′-Triphosphate Be Used to Select Treatment in Severe Vasovagal Syndrome?
Circulation, 1997BackgroundSelection of treatment in vasovagal syndrome should be guided by the mechanism of symptoms. This study determined whether a simple drug test may assess one mechanism.Methods and ResultsTo identify patients at risk of severe cardioinhibitory response of vagal origin, we infused 20 mg ATP into 316 patients hospitalized for recurrent syncope (n ...
