An echocardiography is a medical test that uses sound waves to create detailed images of the heart's structures, including the valves and chambers. By using a device called a transducer placed on the chest, it sends sound waves that bounce off the heart and are turned into moving pictures. These images help doctors see how the heart is working, including how well it pumps blood and how the heart valves are functioning. Echocardiography is often used to diagnose and monitor heart conditions, such as heart disease or valve problems. The test does not involve any surgery or needles and usually takes about 30 to 60 minutes.
