Pediatric Cardiac Electrophysiology is a specialized field within pediatric cardiology that focuses on the study and treatment of abnormal heart rhythms (arrhythmias) in children. Unlike the traditional approach of pediatric cardiac catheterization, which primarily deals with structural issues of the heart, pediatric cardiac electrophysiology specifically addresses the electrical aspects of heart function. In this field, highly trained pediatric electrophysiologists utilize advanced technologies and techniques to diagnose and manage arrhythmias in children. These abnormal heart rhythms can range from simple, benign conditions to more complex and potentially life-threatening issues. The goal of pediatric cardiac electrophysiology is to understand the electrical signals that regulate the heart's rhythm and to develop targeted interventions to correct any abnormalities. One common tool used in pediatric cardiac electrophysiology is the electrophysiology study (EPS). During an EPS, specialized catheters are carefully threaded through the blood vessels to the heart. These catheters record the heart's electrical activity and help identify the source of the arrhythmia. Once the abnormality is pinpointed, various treatment options can be considered.
