Syncope (pronounced “sin ko pea”) is the brief loss of consciousness and posture caused by a temporary decrease in blood flow to the brain. Syncope may be associated with a sudden fall in blood pressure, a decrease in heart rate or changes in blood volume or distribution.
The person usually regains consciousness and becomes alert right away, but may experience a brief period of confusion.
Syncope is often the result of an underlying medical condition that could be related to your heart, nervous system or blood flow to the brain.
