Research Progress on Situational Syncope

Situational syncope refers to syncope that occurs in specific situations and is a special type of neurally mediated syncope. The etiologic composition of situational syncope varies between adults and children. In adults, it is more common during micturition and defecation, whereas in children, it is more frequently seen during flag-raising, micturition, and defecation. The clinical features and underlying mechanisms of various types of situational syncope also differ in terms of age and sex. The treatment of situational syncope mainly includes nonpharmacologic treatment, pharmacologic treatment, and surgical treatment. Adverse events related to situational syncope are rare, and the prognosis is generally good if there are no other systemic diseases. However, in patients with underlying cardiovascular diseases, situational syncope can lead to serious cardiovascular adverse events.
