| Introduction |
|---|
Syncope, defined as transient loss of consciousness with loss of postural tone but with spontaneous recovery,1 accounts for 3% of Accident and Emergency attendances2 and 1% to 6% of hospital admissions annually,3 and has a prevalence of up to 23% in the institutionalized elderly.4 In last month's review,5 we described the head-up tilt-table test and its use in the diagnosis of the vasovagal syndrome, the commonest cause of syncope. This article aims to provide an overview of the management of the vasovagal syndrome, on the basis of current evidence and our experience in this field. Throughout the article, the terms `vasovagal syncope' and `vasovagal syndrome' will be used interchangeably.

Syncope is the most common presenting symptom of the vasovagal syndrome, though patients may present with pre-syncope and dizziness without loss of consciousness. A prodromal syndrome of variable duration is common, with light-headedness, weakness, a sensation of air-hunger or hyperventilation, detachment
