    Risk of having a nuclear stress test with atrial fibrillation
    My husband is in Atrial Fib and is on coumadin he was to have a cardiovversion after 4 weeks of INR of 2-3 but his cardiologist was out of town so it wasn't done and now he has to wait another 4 weeks. In the meantime his doctor has ordered a nuclear stress test. Should the stress test be postponed until after the cardioversion. What are the risks if he has the stress test with his heart out of rhythm?
    James Beckerman, MD, FACC responded:
    It is possible that his heart rate could become more elevated with exercise, but this risk is not specific to the stress test itself.
