To discuss the basic principles of the cardiac electrical conduction system
To recognize the formation of the 12-lead electrocardiogram (ECG)
To recall the changes in physiology that occur in the normal newborn heart and how this is exhibited in the pediatric ECG
Electrocardiography is typically the first cardiac test ordered in adult and pediatric patients presenting with potential cardiac abnormalities. Pediatric patients have unique physiology that rapidly changes from fetal to infant ages and then throughout childhood. These physiologic changes are reflected by changes in the electrocardiogram. In this series of case presentations, you will learn to identify common conditions that are reflected in the pediatric ECG.
