We've prepared a list of questions to help you talk with your pediatric cardiologist.

If your child has an arrhythmia, it means his or her heart is beating irregularly. Electrophysiologists (EPs) are cardiologists who specialize in heart rhythm disorders. At Children’s National Heart Institute, we have one of the few programs in the region specifically dedicated to the treatment of arrhythmia in fetuses, infants, children, adolescents and young adults with congenital heart disease

Electrophysiology at Children’s National: Why Choose Us

Children’s National is one of the top pediatric cardiac centers in the nation. When your child needs treatment for a heart rhythm disorder, you can feel confident that you are in expert hands. All members of our EP team have years of experience diagnosing and treating arrhythmias in children.

Our EP program offers care that is:

  • Advanced. We have all the necessary resources to provide the full spectrum of arrhythmia care for your child. We use the latest techniques in cryoablation and device implantation to ensure a safe, effective treatment for your child. We also provide X-ray free ablation, avoiding the need for X-ray exposure.
  • Experienced. The team performing EP procedures, including catheter ablation, has decades of experience in treating children and teens. Our team consists entirely of pediatric specialists including:
    • Electrophysiologists   
    • Nurses and nurse practitioners
    • EP technicians
    • Cardiac anesthesiologists
  • Child-centered. Caring pediatric nurses that are with you from the moment you enter our hospital. Smaller catheter sizes that are more comfortable for your child. These are just some of the steps we take to provide a positive, pleasant experience for you and your child.
  • Comprehensive. Your child’s care doesn’t end when the procedure is over. Our Cardiac Procedure Recovery Unit (CPRU) is a child-friendly recovery room. There, children receive expert, compassionate care from our pediatric nursing and support staff as they recover from their procedure.
  • Convenient. We offer outpatient ablation for some patients, meaning your child can go home the same day. We also offer EP clinics around the region, so you can complete the diagnostic process locally, where you live. 

    Electrophysiology Procedures We Perform

    We provide the full spectrum of procedures for diagnosing and treating heart rhythm disorders in children. Procedures we perform include:

    • Cardiac ablation. During this procedure, we use a thin wire called a catheter to destroy the area of the heart tissue that is causing the abnormality. Learn more about cardiac ablation at Children’s National.
    • Pacemaker and defibrillator implantation. These are devices we place on your child’s heart to help regulate the heart rhythm. Learn more about pacemaker and defibrillator implantation at Children’s National.
    • Diagnostic tests. For your convenience, you can visit one of our numerous EP clinics in the region for diagnosing arrhythmias. Our experienced EPs travel to the clinics to perform a wide variety of diagnostic tests. This service saves you and your child a trip to our main facility and allows you to begin the diagnosis and treatment process right near home. 

    Electrophysiology Regional Clinics

    At Children’s National, we are where you are. Visit one of our numerous regional outpatient clinics for expert diagnosis of heart rhythm disorders (arrhythmias). Our convenient local clinics are located throughout the region. Some of the diagnostic procedures we perform at our clinics include:

    • Stress testing. This tests your child’s heart rhythm both at rest and after exercise (or after we administer a medicine that simulates exercise).
    • Ambulatory heart rhythm monitoring. These are monitors that your child wears, either for one day or up to a month, depending on the type of monitor. As your child continues his or her normal routine, the monitor evaluates your child’s heart rhythm, collecting important data. Then, our pediatric cardiologists analyze the data and can make a diagnosis. The heart rhythm monitors we use are small, specially designed for a child’s body.
    • Tilt table. This test can diagnose unexplained fainting spells. 

    After the evaluation, we will discuss care recommendations and next steps. If we diagnose your child with an arrhythmia, you can continue to receive care with our cardiac EP specialists at our main facility.
