Overview
Syncope has passed through various attempts to define it, the last one being; a transient loss of consciousness due to cerebral hypo perfusion. Syncope belongs to the non- traumatic causes of T-LOC.
Historical Perspective
Syncope was defined by European Task Force in 2009 Guidelines as the transient loss of consciousness (T-LOC), due to cerebral hypoperfusion. The T-LOC was characterized by four features:
- Transient
- Rapid onset
- Brief duration
- Spontaneous recovery
Previous definitions did not included the cause of the T-LOC (cerebral hypoperfusion). This lead to incorrect diagnosis, because T-LOC, includes a series of other pathologies that are not caused by hypoperfusion, such as seizures, epilepsy, metabolic disturbances (hypoglycemia, hipoxia), vertebrobasilar TIA (transient ischaemic attack), intoxication, among others.
