A case of nocturnal fainting: supine vasovagal syncope

Show Summary Details

Preview

Supine loss of consciousness is a relatively rare occurrence prompting investigations for underlying causes as diverse as cardiac arrhythmia, hypoglycaemia and nocturnal epilepsy. Neurally mediated syncope is rarely implicated as the cause of symptoms in supine loss of consciousness because of the absence of orthostatic stress and gravitational relative preservation of cerebral perfusion, but we report here on a case of recurrent, atypical and troublesome vasovagal syncope occurring at night while supine. Diagnosis aided by head-up tilt table testing and conservative management brought about complete resolution of symptoms.
