What are the 4 classifications of syncope?
Syncope is classified as neurally mediated (reflex), cardiac, orthostatic, or neurologic (Table 1).
What is the most common cause of syncope?
Vasovagal syncope (also called cardio-neurogenic syncope)
Vasovagal syncope is the most common type of syncope. It is caused by a sudden drop in blood pressure, which causes a drop in blood flow to the brain. When you stand up, gravity causes blood to settle in the lower part of your body, below your diaphragm.
What is the difference between syncope and near syncope?
Fainting (syncope) is a temporary loss of consciousness (passing out). This happens when blood flow to the brain is reduced. Near-fainting (near-syncope) is like fainting, but you do not fully pass out. Instead, you feel like you are going to pass out, but do not actually lose consciousness.
What is a diagnosis of syncope?
Orthostatic syncope is diagnosed when there is documentation of orthostatic hypotension (defined as a decrease in systolic blood pressure ⩾20 mm Hg or a decrease of systolic blood pressure to <90 mm Hg) associated with syncope or presyncope.
