Paediatric Syncope in the Emergency Department

This study is looking at children and teenagers who have a brief fainting episode (syncope) and come to the emergency department. Fainting in children is very common and usually benign, but it can sometimes signal a serious underlying heart or brain condition. The study aims to develop better tools to quickly identify which children are at low risk (and can safely go home) versus those who need further evaluation — reducing unnecessary testing while keeping patients safe.
