Arrhythmias in Children

You want your child’s heart to beat strong and steady, from infancy throughout their lifetime. When you seek treatment for your child’s arrhythmia at Duke Children’s, that’s our goal, too.

Understanding Arrhythmias in Children

A child's normal heartbeat changes with age. However, when a child’s heart beats too fast, too slow, or irregularly, it’s called an arrhythmia. An arrhythmia could indicate that there is a problem with the body’s electrical signals that tell the heart muscle when and how to beat.

Arrhythmias can occur in children before birth, but most develop after birth. They can occur in infants, young children, or teenagers. There are many causes of arrhythmias, including imbalances of electrolytes in the blood, certain medications, abnormal electrical pathways in the heart muscle, congenital heart defects, a heart muscle disease called cardiomyopathy, or genetic heart cell problems that can occur in families (such as Long QT Syndrome). Arrhythmias may also occur following heart surgery.

Arrhythmias can be harmless -- or they can cause dizziness, fainting, or even sudden cardiac death. If your child has an abnormal heartbeat, it’s important to have it checked by a pediatric cardiologist. Your child may be seen by a pediatric electrophysiologist, who specializes in heart rhythm disorders in children.

Diagnosing and Treating Your Child’s Arrhythmia

Our pediatric cardiologists have the expertise to evaluate your in child's symptoms, which may include:

  • Fainting
  • Palpitations
  • Irregular heart rhythms
  • History of sudden cardiac arrest

If your child has had fainting episodes, it may be a sign of a heart rhythm issue, or it could have another cause -- for example, a problem with the autonomic nervous system (the part of the nervous system that controls “automatic” body functions, such as heartbeat and breathing). Our team will thoroughly evaluate your child to determine the cause of their fainting and recommend the most appropriate treatment.

If your child is diagnosed with an arrhythmia, you can rely on Duke Children’s for comprehensive, expert heart care. Our children’s heart care program is ranked among the best in the nation by US News and World Report.

Your child’s care team will include:

  • A pediatric electrophysiologist who has completed additional training in diagnosing and treating heart rhythm disorders in children. All of our pediatric electrophysiologists have years of experience performing advanced procedures to treat problems with electrical signals in the heart.
  • A dedicated pediatric procedure team -- including anesthesiologists and nurse anesthetists -- all of whom are certified specialists with specific training in providing care for children’s hearts.

Advanced Pediatric Arrhythmia Care

At Duke Children’s, your child will benefit from the most advanced treatments available, delivered in a compassionate and family-focused environment.

  • Our two dedicated pediatric cardiac catheterization and electrophysiology labs have the latest 3-D mapping systems, allowing the greatest precision for procedures on the smallest, most delicate hearts.
  • We perform procedures with the lowest possible radiation dose to minimize any future health risks.
  • If your child has a pacemaker or defibrillator, we can keep track of their heart rhythms between visits with remote monitoring, saving you travel time. A monitoring station in your home sends data from your child’s device to their care team, who will evaluate it and determine whether a clinic visit is needed.
  • If your child’s heart problem is diagnosed before birth, we work with our fetal cardiology team to ensure your child gets appropriate care -- including having a pacemaker implanted, if needed -- as soon as possible after delivery.
  • If someone in your family has been diagnosed with a genetic disease that causes arrhythmia, we partner with our colleagues in adult electrophysiology to evaluate family members who may have inherited the condition and help coordinate care for the entire family.
