A cardiac ultrasound, or echocardiogram, uses high-frequency sound waves to create pictures of the heart, including the chambers, valves, walls and blood vessels. This test helps evaluate the overall function and integrity of the heart.
A vascular ultrasound is a similar procedure that is used to examine the circulation in the blood vessels in the body and can identify blockages and detect blood clots.
A stress echocardiogram is another test that uses ultrasound imaging to evaluate how well the heart is working. For this test, images of the heart are taken before and immediately after the patient exercises.
