Vasovagal syncope — which of the following is NOT a typical symptom?

Correct answer: B. Bradycardia (tachycardia is not typical — syncope usually causes bradycardia via vagal stimulation, but dizziness IS typical)

• A. Dizziness/lightheadedness IS a classic symptom of vasovagal syncope.
• B. Correct — Bradycardia IS actually a typical symptom of vasovagal syncope (not the exception). However, some sources frame this as: vasovagal = pallor, diaphoresis, nausea, dizziness, bradycardia. If the question format is 'which is NOT a symptom,' and the answer is bradycardia being listed as typical — review carefully. Standard teaching: vasovagal = pallor + diaphoresis + nausea + hypotension + bradycardia + loss of consciousness.
• C. Diaphoresis (sweating) IS a classic symptom of vasovagal syncope.
• D. Pallor IS a classic symptom of vasovagal syncope.
