Arrhythmia Center at Children's Hospital Colorado


Since 1993, the Arrhythmia Center at Children's Hospital Colorado has been an internationally recognized program for the treatment of kids with abnormal heart rhythms, known as cardiac arrhythmia. Our patients range in age from the fetus through the young adult. 

Patients may be referred to our Arrhythmia Center for symptoms such as a rapid heartbeat, too slow of heartbeat, passing out (syncope), extreme fatigue, an abnormal electrocardiogram or holter monitor test result, or a family history of arrhythmia

Why choose Children's Hospital Colorado for the treatment of arrhythmias?

The Arrhythmia Center provides state-of-the-art heart care to babies, kids, teens and young adults. The arrhythmia team consists of board-certified pediatric cardiologists who are leaders in their field and specialize in electrophysiology (the management of heart rhythms). A dedicated cardiac anesthesiologist is also on-call 24/7 to help keep your child comfortable during certain tests and procedures.

To make your visit as convenient as possible, an arrhythmia coordinator is available to help your family as needed and schedule appointments and procedures.  What's more, our state-of-the-art facilities, with family waiting rooms, a pre/post area for surgery and catheterization, and electrophysiology laboratories, are all designed with our patients and families in mind.

What conditions does the Arrhythmia Center evaluate and treat?

Our heart experts at the Arrhythmia Center evaluate patients for:

  • Heart rhythms that are too slow, too fast, or irregular
  • Fainting (known as "syncope"), sudden collapse, and sudden arrhythmias that could cause death
  • Abnormal heart rhythms that tend to run in families

Specific diagnoses include:

  • Atrial flutter
  • Atrial fibrillation
  • Ectopic atrial tachycardias
  • Supraventricular tachycardias caused by accessory pathways (which are extra electrical connections in the heart)
  • Wolff-Parkinson-White syndrome
  • Ventricular tachycardias
  • Torsades or torsades des pointes
  • Long QT syndrome
  • Brugada syndrome
  • Catecholamine sensitive ventricular tachycardia
  • Arrhythmogenic right ventricular cardiomyopathy
