An echocardiogram is a non-invasive medical imaging test that uses ultrasound waves to produce images of the heart's structure and function. It provides information about the heart's chambers, valves, and blood vessels, and can help diagnose heart conditions such as heart valve disease, cardiomyopathy, and coronary artery disease. The test can also help evaluate the heart's pumping function and measure blood flow through the heart.
