Electrophysiology service

The heart is a pump that is constantly beating to deliver blood to all parts of the body. For the heart to be effective, the heart’s “plumbing system” and “electrical system” must both work well together. Whenever there is a suspected problem with a patient’s heart, cardiologists with special training figure out what the problem is, and determine the best way to approach the problem. In children, many of these problems involve the plumbing of the heart; that is, the size and strength of the cardiac chambers, any holes in the heart that don’t belong, the valves that help blood move forward in one direction through the heart (and not backward!), and the blood vessels bringing blood into and out of the heart.

However, for the heart to work properly, all parts of the heart’s plumbing system also have to be well coordinated; this coordination is accomplished by the heart’s electrical system. The electrical system “listens in” to what else is going on in the body (for example, the individual is at rest or asleep, up and walking around, playing and jumping, or angry or sick), and adjusts the heartbeats accordingly – slow and steady when deeply asleep, and much faster with exercise.

Sometimes the heart’s normal electrical coordination is disturbed, causing the heart to beat too fast, too slow or very irregular. When this happens, the person may feel funny heartbeats (palpitations), chest pain , lightheaded or dizzy, possibly faint (syncope ), or even worse. Some patients with otherwise seemingly normal hearts can suddenly develop disturbances in the heart’s rhythm (so-called “arrhythmias”). Patients born with plumbing abnormalities (holes in the heart, abnormal valves, etc.) are more likely to develop arrhythmias, whether or not they’ve had surgery to correct or improve the heart’s plumbing.

At Norton Children’s Heart Institute, affiliated with the University of Louisville, we have a specialized cardiology team with expertise in diagnosing and treating arrhythmias in children and adults with congenital heart disease. These cardiac “electricians” are available 24/7 to work with many other healthcare teams, including other cardiologists and heart surgeons focusing on the heart’s “plumbing”, and providers in the emergency room, pediatric and neonatal intensive care units, in outpatient clinics in Louisville Metro and across the KY Commonwealth, and through online web-based services.

These “electricians of the heart” are able to find out what causes abnormal heartbeats in any patient through a careful understanding of the patient’s circumstances (eg; specific symptoms, prior medical history, etc.) and the use of tests including different types of electrocardiograms. Sometimes a minimally invasive procedure like an EP study is required to confirm the diagnosis. Once complete understanding of the patient’s arrhythmia has been made, physicians may or may not need to treat the problem. If treatment is required, we have the experience, resources and support to treat any cause, whether that involves medication, catheter-based treatments like ablation, implanting a pacemaker or defibrillator, or working with our heart surgeons during open heart surgery.

Norton Children’s Hospital is home to Kentucky’s only electrophysiology laboratory dedicated to children. At Norton Children’s Heart Institute, our electrophysiologists work closely with specially trained nurses and technicians in the Electrophysiology Laboratory to fully evaluate, treat and often cure many arrhythmias in children.
