Overview

• Because vasovagal syncope may be precipitated by the sight of blood, loss of blood, sudden stressful or painful experiences, surgical manipulation, or trauma, a history of childhood syncope may provide a clue to the cause of vasovagal syncope in adults.

Prodrome

Most patients complain of a prodome consisting of:

• Nausea
• Diaphoresis
• Lightheadedness
• Blurred vision
• Headache
• Palpitations
• Paraesthesia
• Pallor
• “Washed out” and tired feeling

The symptoms usually occur in the upright position and resolve almost immediately when the patient assumes the supine position.
