Pediatric cardiology is a specialized branch of medicine that focuses on diagnosing and treating heart conditions in children, from newborns to young adults. Pediatric cardiologists are trained to understand the unique heart issues that can arise in children, including congenital heart defects, arrhythmias, and heart murmurs. These specialists use various tools, such as echocardiograms and electrocardiograms, to assess heart health and function. Treatment may involve medication, lifestyle changes, or surgical interventions, depending on the specific condition. The goal of pediatric cardiology is to ensure that children with heart problems can lead healthy, active lives.
