A pediatric cardiologist is a doctor who specializes in diagnosing and treating heart conditions in children, from newborns to young adults. They focus on various heart issues, including congenital heart defects, arrhythmias, and heart murmurs. These specialists work closely with families to provide care tailored to each child's unique needs. Pediatric cardiologists often collaborate with other healthcare professionals, such as pediatricians and cardiac surgeons, to ensure comprehensive treatment. They may perform tests like echocardiograms and electrocardiograms to assess heart function and monitor any changes over time. Their goal is to help children lead healthy, active lives despite their heart conditions.
