Arrhythmia Care at Norton Children’s Heart Institute

The heart is a muscle that is constantly beating to pump blood through tubes (blood vessels) to all parts of the body. The heart’s “plumbing system” and “electrical system” must both work correctly for the heart to work as it should.

The heart’s normal electrical system synchronizes the beating of the heart’s chambers. When the electrical system does not work well, disturbances in normal heart rhythm (arrhythmias) cause abnormal heartbeats, such as too rapid, too slow or not very regular.

These arrhythmias can cause symptoms such as fluttering and palpitations. The abnormal heartbeat sometimes can reduce heart function.

Physicians usually treat these disturbances in heart rhythm with medication, minimally invasive procedures or implanted cardiac electrical devices. At Norton Children’s Heart Institute, affiliated with the University of Louisville, electrophysiologists work closely with specially trained nurses and technicians in the electrophysiology laboratory to fully evaluate, treat and often cure many arrhythmias in children.

State-Of-The-Art Technology to Treat Arrhythmias

Electrophysiology services include:

• Defibrillator insertion
• Intracardiac electrophysiology studies
• Transesophageal electrophysiology studies
• 3-D mapping
• Catheter ablation with radiofrequency or cryoablation technologies
• Insertion of pacemakers — small, battery-powered medical devices designed to electrically stimulate the heart muscle in an effort to restore a more normal heart rhythm
• Loop recorder insertion
