Arrhythmia

Expert Care for Irregular Heartbeat

An arrhythmia is a heartbeat that’s not regular. Examples would be beating too slowly (bradycardia) or too quickly (tachycardia), which causes problems like dizziness or fatigue. In most cases, arrhythmias are caused by an electrical “short circuit” in the heart, but they can also be caused by hormones produced by the thyroid. Many children with a heart arrhythmia never experience symptoms and don’t need medical care. However, in some cases, an experienced pediatric heart expert will need to identify and treat your child’s arrhythmia.

At Nemours, our team of experienced children’s heart experts is here to provide the personalized care your child needs. Our board-certified, fellowship-trained pediatric cardiologists and cardiothoracic surgeons (specialize in surgical procedures of the chest, including the heart and lungs) can provide answers to your questions, address your concerns and offer the latest treatment options for all types of heart arrhythmia. Our cardiac team provides children with research-backed care, delivered in a family-centered setting.

Services We Offer for Heart Arrhythmias

Cardiac arrhythmia doesn’t always need treatment. We offer extensive diagnostic and treatment services, which may vary depending upon the condition and location, including:

Cardiology. Your child’s heart specialist may prescribe a medication or combination of medications that can help to stabilize the heartbeat, as well as treat the underlying cause of the problem.
Cardiac Catheterization. If medications aren’t enough to treat your child’s arrhythmia, the cardiac specialist may recommend catheter ablation, a procedure used to diagnose or treat cardiac problems by inserting a thin plastic, flexible tube (called a “catheter”) into an artery or vein, and threading it through the bloodstream into the heart and its large blood vessels.
Cardiac Diagnostic Testing and Kid-Friendly Imaging. State-of-the-art, noninvasive and minimally invasive tests for kids of all ages, including fetal testing (for babies still in the womb), echocardiogram, and tilt table testing.
Endocrinology. Experts in pediatric hormones, since some arrhythmias are caused by problems with the thyroid.
Heart Surgery (Implanted Devices or Ablation). Your child’s heart specialist may recommend a pacemaker, a device that uses electrical impulses to help the heart beat more regularly. Similar to a pacemaker, an implanted defibrillator is a device that can also help the heart beat more regularly. Depending on your child’s condition, your heart surgeon may recommend ablation surgery.
