Emotion-triggered cardiac asystole-inducing neurocardiogenic syncope.
The pathophysiology of neurocardiogenic syncope (NCS) is multifactorial. Recurrent syncopal episodes can result in injury and can provoke substantial anxiety among patients. Although an abundance of descriptions of various forms of syncope have been reported in the literature, few articles to date address a documented case due to emotional stress or sound. This is a report of a 31-year-old woman who fainted after being startled by someone sneezing. Review of the episode on her event recorder revealed a transient cardiac asystole of 10 seconds. We discuss the incidence of NCS and the proposed mechanism by which this syncopal event occurred.
