Electrophysiology & Heart Rhythm Program

If an abnormal rhythm occurs, it's important to find out what kind it is, as treatment recommendations depend on its type. That’s where we can help. We offer personalized, trusted arrhythmia care that is tailored to each patient’s unique needs.


Our Pediatric Electrophysiology & Heart Rhythm team has implanted more than 600 pacemaker/defibrillators and currently follows nearly 350 patients in a pacemaker clinic, providing them with comprehensive outpatient care. Patients with pacemakers can also be followed with the latest remote home monitors to minimize outpatient visits and hospitalizations.

A common way of treating arrhythmia is with catheter ablation. During ablation, a doctor inserts a thin, flexible tube into the patient’s heart. A special machine delivers hot or cold energy through the tube to tiny areas of the heart muscle that cause the abnormal heart rhythm. This energy destroys the small piece of heart tissue which was causing the abnormal rhythm. At Phoenix Children’s, 95% of our ablations result in a "cure," avoiding the need for lifelong anti-arrhythmic medication therapy.
