ALD Stress Test
The test is done in two parts. An IV will be placed in your arm. During the first part, you will have a radioactive tracer injected into your bloodstream. After a short wait, resting images of your heart will be taken.
Electrodes will be placed on your chest to record the heart’s activity. The blood pressure cuff on your arm will be inflated every few minutes. Baseline measurements of heart rate and blood pressure will be taken before exercise starts and continue during the entire test and into recovery.
For patients who are unable to walk on a treadmill, IV medication is given to dilate the heart vessels (like during exercise) to satisfy the desired test requirements.
During this portion, a radioactive tracer (Sestamibi) will be injected through the IV, and later, pictures will be taken of the heart. These images show how blood flows to the heart during the stress portion of the test.
The entire test can take about 3-5 hours.
A physician is present during the stress portion of the test.
