when other serious causes have been excluded. some patients feel as though everything is going dark, and then they suddenly become unresponsive. syncope usually occurs when the patient is standing up or when the patient suddenly stands up from a sitting position. the collapse that follows puts ...

Defining syncope is critical in order to identify its cause, clarify the mechanism, and understand concomitant risk of recurrence and associated adverse outcomes, as syncope can be confused with other causes of altered, or complete loss, of consciousness, as well as collapse....
The collapse and loss of consciousness that occur during fainting or syncope are due to the abrupt cutting off of the energy substrates to the cerebral cortex. This is usually through a sudden decrease in cerebral perfusion by oxygenated blood from a reduction in cerebral blood flow itself, a ...
Currently, approximately one-third of syncope/collapse patients seen in the emergency department (ED) or urgent care clinic are admitted to hospital for evaluation. The primary objective of developing syncope/TLOC risk stratification schemes is to provide guidance regarding the immediate prognostic risk...
