What happens during the Lexiscan stress test?
After medical history is reviewed and paperwork completed, an IV is placed in your arm/hand. Electrodes (metal plates) are placed on your chest to monitor your heart during the test. A small amount of radioactive tracer is injected through your IV. Pictures are captured for about eight minutes that show blood flow to your heart at rest.
After the first round of images are taken, the stress portion of the test is performed. Medication is given to stress your heart. Immediately after the stress medication, a second dose of radioactive tracer in administered and imaging is captured while your heart is in stress. These images show blood flow to your heart when stressed.
Can I bring someone with me to the test?

test begins, only your medical team involved in your test can be in the room.
