Most physiologic reflex mechanisms subserve obvious and logical purposes. For example, the arterial baroreflex responds to hypotension by eliciting tachycardia and vasoconstriction, thus increasing cardiac output and raising blood pressure. The raison d'etre for a reflex such as the Bezold-Jarisch is not immediately apparent.

Dysautonomia and neurocardiogenic syncope
Current Opinion in Cardiology, 2001Syncope in childhood is a common problem. In most children, syncope is benign, secondary to a disturbance in autonomic control of heart rate and blood pressure. It is increasingly evident that neurally mediated syncope is a heterogeneous group of conditions, necessitating a reclassification of autonomic disorders.

Near death and neurocardiogenic syncope
Clinical Autonomic Research, 2007We report the case of an 18-year-old female who presented as an out-of-hospital ventricular fibrillation cardiac arrest. She required ICD insertion and recovered without deficit. Following recurrent syncopal episodes we diagnosed the co-existence of Neurocardiogenic syncope.

Catecholamines and Neurocarondiogenic Syncope
1997Publisher Summary The combination of enhanced adrenomedullary and attenuated sympathoneural responses during slight reductions in cardiac filling antecede the syncope. The findings are consistent with the view that sudden, central resetting of baroreflex function can evoke a pattern of sympathoinhibition combined with adrenomedullary and vagal ...

Diagnosis and management of neurocardiogenic syncope
Current Opinion in Cardiology, 1998The medical term syncope is derived from the Greek word "synkoptein," the original meaning of which was "to cut short". Because it is both a symptom and a sign, the physician may often find the evaluation of syncope a difficult and frustrating endeavor.

Usefulness of pindolol in neurocardiogenic syncope
The American Journal of Cardiology, 1998We prospectively studied the efficacy of pindolol, a beta-adrenergic blocker with intrinsic sympathomimetic activity (ISA), for the prevention of syncope recurrences in 31 patients with recurrent neurocardiogenic syncope. Pindolol proved to be an effective treatment, even in patients who had previously failed treatment with conventional beta blockers ...

Familial neurocardiogenic (vasovagal) syncope
American Journal of Medical Genetics Part A, 2005AbstractVasovagal syncope (VSS) is an exaggerated tendency towards the common faint caused by a sudden and profound hypotension with or without bradycardia. The etiology of VVS is unknown though several lines of evidence indicate central and peripheral abnormalities of sympathetic function.

Neurocardiogenic (Vasodepressor) Syncope
New England Journal of Medicine, 1993Figure 1. Neurocardiogenic (Vasodepressor) Syncope. A 72-year-old woman with breast cancer that had metastasized to the glossopharyngeal region had recurrent episodes of sudden lightheadedness, diaphoresis, and syncope. A dual-chamber pacemaker was implanted, but syncope recurred, always preceded by severe neck pain. During the tilt-table test with the

MEDICAL THERAPY OF NEUROCARDIOGENIC SYNCOPE
Cardiology Clinics, 2001Neurocardiogenic syncope, alternatively called vasovagal, vasodepressor, or neurally mediated syncope, is a clinical syndrome faced by many clinicians. Its pathophysiology is complicated and not fully understood. Multiple pharmacologic therapies have been evaluated, with no clear ideal agent.
