Explanation:

Syncope is a brief loss of consciousness and muscle tone (or posture) that can occur when not enough blood gets to the brain. Syncope is commonly called fainting. In most children, it’s usually harmless. But in a few children, syncope is serious. Fainting may be due to a heart problem, or sometimes a neurological problem. The common reason behind each fainting episode is a temporary lack of oxygen-rich (red) blood getting to the brain. However, many different problems can cause a decrease in blood flow to the brain.The healthcare provider will ask about your child’s symptoms and health history. He or she will give your child a physical exam.
