Nuclear Stress Test

A nuclear stress test measures blood flow to your heart, and can show areas with poor blood flow or heart damage. It also measures how well your heart pumps blood out to your body (called an ejection fraction). If your doctor has ordered a nuclear stress test, a technician will first inject an isotope into an IV line in your arm. You’ll then have a heart scan while you are at rest. Then a technician will place electrodes (small metal discs that detect electrical impulses) on your chest to monitor your heart while you walk or run on a treadmill. If you can’t exercise, you might receive a drug to substitute for exercise. You will receive a second isotope injection during this time, followed by a second heart scan. When your test is complete, you will be able to return home with no restrictions.

Preparing for Your Nuclear Stress Test

Unless your doctor tells you otherwise, continue taking your medications as usual. If you have been instructed not to take your medications, tell the technician before the test. The nuclear stress test will take about three to four hours. In certain instances, the test may be done over two days.

 

  • Please arrive 15 minutes before your scheduled appointment and bring your doctor’s order.
  • Do not eat, drink or smoke for at least four hours before the test.
  • Don’t consume any caffeine (including coffee, decaf coffee, or chocolate) for 24 hours before the test. 
  • Wear loose-fitting, comfortable clothing and tennis shoes or walking shoes. Do not wear one-piece undergarments. 

 

Nuclear stress tests are performed by appointment only.
