Problems may occur anywhere in the conduction system and interfere with effective pumping of blood. These abnormal beats are known as arrhythmias. Special studies of the heart's electrical system may be needed to accurately diagnose the type and cause of the arrhythmia. Therapy for arrhythmias is based on their type and any difficulties they cause the child. Treatment may include medication, cardiac catheterization, placement of a pacemaker, or other surgery.
Many arrhythmias require no treatment as they cause no important problems for the child.
