INCIDENCE, MECHANISMS, AND SIGNIFICANCE

Abstract
A better understanding of mechanisms precipitating syncopal episodes and their likelihood of recurrence can lead to prevention of accidents resulting from syncope and perhaps prevent syncopal episodes at crucial times. Eighty-two persons studied described a total of 113 syncopal episodes occurring sometime in the past. The factors, surrounding the acute clinical episode of syncope, were highly variable. More than one factor may have played a role in the precipitation of syncope in a large number of the cases. The overt act at the time of syncope was most often postural change or pain. Cardiac arrhythmias induced by the common respiratory maneuvers were often associated with syncope. Disturbances in a person's general hygiene not only decrease his stress tolerance but apparently make him more susceptible to syncope.
