Pediatric Syncope

Key Points About Syncope in Children

  • Syncope is a brief loss of consciousness and muscle tone. It’s caused when the brain doesn’t get enough blood. 
  • It's usually harmless, but in a small number of children, it's caused by a heart problem.
  • Syncope is usually diagnosed with a health history and physical exam, including checking blood pressure and heart rate.
  • If there is no serious cause, syncope is managed by finding the cause and learning ways to prevent it.
