Pediatric Arrhythmia

Key points about arrhythmias in children

  • An arrhythmia is an abnormal heart rhythm. It may be a heart rate that is too fast, too slow or irregular.
  • The cause may not be known. In some cases it is caused by a problem that's present at birth, a problem that's inherited, or an infection.
  • There may not be any symptoms. Or a child may have moderate to very serious symptoms.
  • Your child may need to see a pediatric heart doctor (cardiologist) for a diagnosis. Your child may also need tests.
  • Some children don't need treatment. If treatment is given, your child may need medicine, radiofrequency ablation, a device or surgery.
