An echocardiogram is a non-invasive imaging test that uses sound waves to create real-time images of the heart. It provides detailed information about the structure and function of the heart, allowing cardiologists to evaluate the size, shape, and movement of the heart chambers, valves, and blood vessels.

Echocardiograms are valuable in diagnosing various heart conditions in children, including congenital heart defects, valve abnormalities, and heart muscle disorders.
