During the test, your Long Island cardiologist will measure your EKG at resting. You will then be asked to walk on a treadmill at an increasing speed. As soon as you exceed your target heart rate by 85% or experience discomfort, the treadmill will be stopped. You will then be given an injection of a harmless radioactive substance that shows up on a gamma-ray camera. The camera takes pictures of different parts of the heart and sends them to a computer monitor.

After the images have been recorded, your heart doctor in Long Island will ask you to return after 3 to 4 hours. During this period you can go about your daily activities, but do not exercise or consume and caffeine containing products. When you return, the gamma-ray camera will be used once again to take pictures of your heart at resting.

  • Allergic reaction
