An arrhythmia is an abnormal heart rhythm usually caused by an electrical "short circuit" in the heart. The heart normally beats in a consistent pattern, but an arrhythmia can make it beat too slowly, too quickly or irregularly. This can cause the heart muscle's pumping function to work erratically, which can lead to a variety of symptoms, including fatigue, dizziness and chest pain.

The electrophysiology team at Joe DiMaggio Children's Hospital Heart Institute is one of the busiest in the region and specializes in the diagnosis and treatment of cardiac rhythm disturbances and heart arrhythmias in pediatric and adult patients, including:

  • Atrioventricular reentrant tachycardia
  • Cardiac channelopathy
  • Congenital heart arrhythmia
  • Postural tachycardia syndrome postural (POTS)
  • Supraventricular tachycardia
  • Ventricular tachycardia
  • Wolff-Parkinson-White (WPW) syndrome

Our highly-skilled electrophysiology team is led by Ming-Lon Young, MD, a pioneer in ablation therapy in children. He has performed more than 1,500 cases with outstanding outcomes and uses innovative, sophisticated technology to pinpoint the origin of an arrhythmia or the pathway that it uses to spread.

The team performs electrophysiology studies (PES) using advanced cardiac catheterization techniques to test the electrical activity of a patient's heart to determine where an arrhythmia is coming from. We also use some of the latest, most advanced equipment around, including three-dimensional and non-contact mapping systems, to diagnose and treat a variety of heart arrhythmias.

With these results, our cardiac electrophysiologist works closely with your child's clinical cardiologist and/or primary care physician to develop the appropriate course of heart arrhythmia treatment for your child, which may include:

  • Cardiac ablation
  • Cryoablation
  • Implanting a pacemaker or implantable cardioverter defibrillator (ICD)
  • Radiofrequency catheter ablation

We also provide continuum of care and collaborate with adult electrophysiologists when needed.

Other Non-Invasive Diagnostic Tests

Many additional non-invasive diagnostic tests are also available, including:

  • Electrocardiograms (EKG)
  • Holter monitoring
  • Magnetic resonance imaging (MRI)
  • Stress tests
  • Tilt tests
