An echocardiogram is a moving picture of the heart with ultrasound. It shows the chambers, size, their valves and their movement, and even the blood flow. Valves that do not open properly or that leak can be precisely assessed.
Nuclear Stress Test
A nuclear stress test is a way to determine if the heart muscle is getting enough blood. A small amount of tracer is injected in your arm through an IV and a camera is used to obtain an image of the heart. Afterwards, blood flow to the heart is increased either with exercise on a treadmill or with medication. If an artery is significantly blocked, an area of the heart muscle will pick up less of the tracer and appear “cold” on the scan image.
