Pediatric Electrophysiology Program


The Pediatric and Congenital Electrophysiology Program offers a full range of diagnostic and therapeutic modalities for arrhythmias in children or associated with congenital heart disease. Our program performs over 100 catheter based electrophysiology procedures a year and 40 device implants. In addition, there are over 800 clinic encounters and 1000 non-invasive diagnostic studies performed each year.

The available diagnostic modalities include a full range of non-invasive testing, including continuous ambulatory monitoring, transtelephonic event monitoring and exercise testing. Invasive diagnostic modalities include catheter based eletrophysiology testing, implantable loop recorders and transesophageal pacing.

A broad array of therapeutic modalities are also available including catheter-directed radiofrequency or cryoablation therapy for both ventricular and supraventricular arrhythmias. This procedure is performed on an outpatient basis and offers a 95 percent cure rate for tachycardias associated with Wolff-Parkinson-White syndrome as well as refractory cases of PSVT, ectopic atrial tachycardia, and permanent junctional reciprocating tachycardia. More advanced mapping and ablation technologies are available for more complex arrhythmias, including ventricular tachycardia and post operative scar related arrhythmias.

Implantable device therapies are also available, including implantation of pacemakers, defibrillators and biventricular systems. In select cases, device implant can be performed from and axillary approach, allowing for a more cosmetic result. The device program at UCLA includes a comprehensive follow-up clinic, and transtelephonic monitoring. UCLA also works with manufacturers to provide comprehensive in home monitoring for implantable defibrillators, when indicated.

A UCLA pediatric electrophysiologist is on call 24 hours a day to provide consultation for patients with complex rhythm disturbances. Consultation is available regarding a full range of therapeutic alternatives including pharmacologic agents, pacemakers and internal implantable defibrillators.
