title: Vasovagal syncope: management with atrioventricular sequential pacing and beta-blockade.
abstract: A case of vasovagal syncope in an otherwise healthy 74-year-old woman is described. Attempts to prevent symptoms with ventricular and atrioventricular sequential temporary pacing (documented by continuous monitoring of heart rate and intra-arterial recording of blood pressure during spontaneous episodes) proved inadequate. However, the addition of a beta-blocker to permanent DDD pacing was clinically successful in markedly diminishing symptoms. The mechanisms of action of this treatment modality is discussed.
