Permanent cardiac pacing is a promising option for patients with severe vasovagal syncope. Syncope and presyncope are probably the most common cardiovascular symptoms, and the vasovagal reaction is likely to be the cause of most of these symptoms. Although most patients are troubled infrequently, there is a sizable minority with frequent and highly distressing symptoms. Despite progress and recommendations by expert consensus panels about the indications for pacing for vasovagal syncope,<sup>8 Clarke M., Sutton R., Ward D. , et al.

Are patients sufficiently symptomatic to warrant such an invasive and expensive approach? Is pacing useful in a syndrome that may be characterized as much by vasodepression as by bradycardia? Why not concentrate on pharmacologic strategies? If pacing is used, what detection and treatment modes should be used? This article reviews evidence that addresses each of these questions.
