My daughter from age 14-16 has had several episodes of passing out, she would be out for 10 minutes. We took her to pediatric cardiologists, endocrinologists and neurologists. She was finally diagnosed with Autonomic nervous dysfunction and was medicated with fludrocort. She seems to have mostly outgrown this but her most recent episode was while driving and a deer ran out in front of her, the fear of it caused her to pass out. Her boyfriend was on the phone with her when it happened, he heard her scream and then nothing but the car radio. He went looking for her the way she had gone home and found her passed out, her car had gone off the road and was sitting against an embankment. The biggest danger is where they are when this happens, driving, or on a hard floor or hitting something on the way down.
When you stand for a long time, it may cause your knees to buckle resulting in a vaso-vagal reaction. When this happens, there is a decrease in blood pressure which can make a person collapse or faint.
How about cocaine. It causes vaso-constriction of blood vessels in your body including vessels in your heart, which can result in a heart attack.
