Electrophysiology/Arrythmia Management

The Electrophysiology and Arrhythmia Management Program at the Children’s Hospital at Montefiore’s (CHAM) Pediatric Heart Center offers comprehensive diagnostics and treatment for the full spectrum of cardiac rhythm disorders. From fetal stages through adulthood, patients diagnosed with an arrhythmia can benefit from our unparalleled pediatric electrophysiology experience, state-of-the-art diagnostic tools and therapeutic solutions for all arrhythmias. Additionally, our team of expert electrophysiologists works in a pleasant, child-friendly environment designed to make the experience as comfortable as possible.

What Is Electrophysiology Testing, and Why Would My Child Require It?

An electrophysiology (EP) study is a nonsurgical test conducted on patients suspected to have an abnormal heart rhythm. Cardiac catheters and sophisticated computers generate electrocardiogram (EKG) tracings and electrical measurements from within the heart chambers. The test is used for diagnostic purposes or to pinpoint the precise location of electrical impulses that impact the heart’s ability to pump blood.

Your cardiologist may recommend an EP examination if a standard EKG, Holter monitor, stress test, echocardiogram or angiogram does not provide sufficient information to assess an abnormal heart rhythm (arrhythmia). An EP study offers more detailed information about the electrical activity in the heart than other tests because electrodes are placed directly onto heart tissue. Many times, the cardiologist can correct the abnormality during this same procedure.

Prominent Electrophysiology Team at CHAM

At the Children's Hospital at Montefiore, our electrophysiologists are some of the most experienced nationally and around the globe. Robert H. Pass, MD, Director, Electrophysiology and Arrhythmia Management Program, CHAM, has performed more than 1,000 radiofrequency ablations and over 100 cryoablations on patients as young as 6 weeks of age.

Christine A. Walsh, MD, is Co-Director of the Montefiore Einstein Center for CardioGenetics, which uses the latest in diagnostic techniques, including advanced genetic testing, to search for the arrhythmogenic causes of sudden death and counsels families and physicians on the prevention of a reoccurrence.

Dr. Bradley Clark is an expert in pacemaker and defibrillator implantation and management, as well in cardiac arrhythmia management. He is presently conducting research on novel means of implanting defibrillator leads in children using less invasive approaches. He and Dr. Pass are both committed to reducing radiation exposure to patients during electrophysiologic procedures and have published extensively on this topic. Dr. Clark completed medical school at UMDNJ, now known as Rutgers Biomedical and Health Sciences. He did his general pediatric cardiology fellowship at Children's National Health Center, as well as his pediatric electrophysiology training. 

Our multidisciplinary team of extraordinary cardiac arrhythmia specialists, pediatric nurses and technicians, trained in this subspecialty as well as pediatrics, possesses the diverse skills needed to successfully treat children with arrhythmias.

Advanced Treatment Options

Thanks to various treatment options, most children with arrhythmias are able to lead active lives. Certain arrhythmias may be effectively managed with medication, while others may require an ablation procedure or implantable pacemaker. At CHAM, our team of experts will customize your child’s treatment plan in order to maximize his or her quality of life. Some of the treatment options offered at CHAM include the following:

  • Intracardiac ablation (radiofrequency ablation or cryoablation): Sometimes when an EP study shows that an arrhythmia is stemming from a specific point in the heart, it is possible to ablate, or remove, the area. During this procedure, a thin catheter (tube) is inserted into a vein and then into the heart. The tip of the catheter carries a special device that emits a low level of radiofrequency waves (or extremely cold, thermally conducted fluids in the case of cryoablation), which remove the abnormal tissue in the heart. Children who were dependent on drug therapy have often been “able to move forward with life without need for medications or athletic restrictions after undergoing this procedure," notes Dr. Pass.
  • Pacemaker: A pacemaker is a small, battery-powered implantable medical device that regulates the heart rate through electrical impulses. When the beat slows below an acceptable level, the pacemaker emits impulses to resynchronize the heart and improve blood flow.
  • Implantable cardioverter defibrillator (ICD): Similar to pacemakers, an ICD is a small device implanted beneath the skin near the collarbone and is programmed to regulate the heartbeat. However, ICDs are capable of treating both slow and fast heart rhythms and are typically prescribed for the latter. When the heart beats faster than the acceptable level, the device emits a small shock to slow the heart.
