Pediatric Electrophysiology

Pediatric electrophysiologists are cardiologists who study the electrical system of your child’s heart. Through specialized equipment located inside the cath lab, electrophysiologists perform three-dimensional mapping and navigation of the heart to discover the heart’s rhythm patterns. These maps help to pinpoint the origin of abnormal rhythms, or arrhythmias.

Electrophysiologists use radiofrequency ablation (heating) or cryoablation (freezing) to correct the heart’s rhythm.

Our electrophysiology team also implants and monitors pacemakers and implantable cardiac defibrillators (ICD) in children. The devices are programmed according to your child’s age, cardiac disorder and arrhythmia. In addition to providing this care for children, we also care for Adult Congenital Heart Disease patients.
