SYNCOPE

1. Syncope

2. • Syncope is a transient and abrupt loss of
consciousness with complete return to
preexisting neurologic function. It is
classified as neurally mediated (i.e.,
carotid sinus hypersensitivity, situational,
or vasovagal), cardiac, orthostatic, or
neurogenic.

3. • Neurally mediated syncope is the most
common and is seen primarily in young
adults.
• A reflex response causes vasodilation,
bradycardia, and systemic hypotension
leading to decreased cerebral blood flow.
• Neurally mediated syncope includes
vasovagal syncope, situational syncope,
and carotid sinus
syndrome/hypersensitivity.
