Heart Rate Slowed After Injection During Nuclear Stress Test. Sweating, Nausea. Am Diabetic. Meaning?
I am taking care of a 82 year old gentleman who has had a 5 way bypass in 2003. Today he had a nuclear Stress Test, during this test his heart rate before the injection was 50-70BPM. after the injection it slowed to 30 BPM. What does this mean? He was covered in sweat and thought he was going to vomit . He is also a diabetic.

Dear caregiver,
Thanks for your concerns. Most likely he was given a substance called adenoseine, which is given through an IV to simulate exercise response in the heart; one of the side effects is transient heart block with slow heart rates, which is probably what he exprienced and made him feel bad with those symptoms; it is just a side effect of the medication, which can be more common with old adults.
Yours truly,
