Cardiac Arrhythmias in Experimental Syncope

Abstract

Fifty young, apparently healthy aviation cadets in preflight training were evaluated with regard to syncope. Thirty percent of these subjects admitted that they had experienced previous, undisclosed syncope, when they were not in fear of detection or removal from the training program. Twenty-one of the cadets experienced experimental syncope during the syncope procedures. Cardiac arrhythmia was frequently associated with the syncopal episode and cardiac arrhythmia was frequently induced by respiratory maneuvers without syncope. Intravenous administration of atropine apparently prevented recurrence of cardiac arrhythmia induced by respiratory maneuvers. Significant cardiac arrhythmia was also noted in simple orthostatic syncope.
