neurocardiogenic syncope

A syncope with a psychogenic substrate and predisposition to bradycardia, hypotension and peripheral vasodilation.
 
Clinical findings
Abrupt loss of vascular tone; nausea; diaphoresis; pallor.
 
Diagnosis
Tilt test, in which the patient is placed on a tilt table at a 40º to 80º angle from horizontal and maintained in a motionless upright position for 10–15 minutes or more.
 
Management
Beta blockers—e.g., metoprolol, theophylline, disopyramide.

Mechanism
Uncertain; probably activation of myocardial mechanoreceptors (C fibres), with decreased efferent sympathetic tone and increased efferent parasympathetic tone.
