Wear comfortable clothing and shoes, suitable for exercise. A technologist will first clean three areas on your chest, and then place three small self-sticking electrodes on those areas. Then the nuclear technologist will give you two injections. You will lie down on a special bed. A nuclear camera will surround you, taking pictures of your heart.
Some people feel a little claustrophobic.
This part of the test may last for 20 minutes. If you are having a test at rest, the technologist will take three pictures of your heart. After the rest portion of the test, you may go on to the exercise portion of this test. In the exercise portion, you will lie on your back and place your feet into pedals. Then while remaining in a supine position, you will pedal as if on a bicycle.
