Episode notes
Definition And Key Features Of Syncope
- Syncope is a rapid, brief loss of consciousness due to global cerebral hypoperfusion, most often from hypotension.
- Rapid recovery without prolonged confusion suggests syncope rather than seizure or hypoglycemia.
Three Primary Syncope Categories
- There are three main syncope types: cardiac, reflex (vasovagal), and orthostatic.
- Identifying the type guides urgency and disposition because cardiac syncope can be life-threatening.
