Syncope is defined as a transient loss of consciousness and postural tone due to an alteration in cerebral perfusion, usually associated with spontaneous recovery. In pediatric patients, syncope is most often a brief episode with complete recovery, without sequelae.

Syncope is most common in teenagers, with the incidence peaking in patients aged between 15 and 19 years.
