ECHO

Echocardiography, or echo, is a painless test that uses sound waves to create moving pictures of your heart. The pictures show the size and shape of your heart. They also show how well your heart's chambers and valves are working. We recommend echocardiography (echo) if you have signs or symptoms of heart problems.

For example, shortness of breath and swelling in the legs are possible signs of heart failure. Heart failure is a condition in which your heart can't pump enough oxygen-rich blood to meet your body's needs. Echo can show how well your heart is pumping blood.

Echo also can help your doctor find the cause of abnormal heart sounds, such as heart murmurs. Heart murmurs are extra or unusual sounds heard during the heartbeat. Some heart murmurs are harmless, while others are signs of heart problems.

Echo also can pinpoint areas of heart muscle that aren't contracting well because of poor blood flow or injury from a previous heart attack. Echo can detect possible blood clots inside the heart, fluid buildup in the pericardium (the sac around the heart), and problems with the aorta. The aorta is the main artery that carries oxygen-rich blood from your heart to your body.
