I am new to Mayo Connect, posting because I am concerned about a nuclear stress test scheduled for 10 days from now. After wearing a heart recording device I was told the results were "crystal clear" that I have AFib and atrial flutter. Cardiologist told me I needed a Lexiscan nuclear stress test. I asked her if the heart recorder showed any episodes of abnormally low heart rate, and she said no. I know I've had episodes of bradycardia as well as tachycardia. I have a pulse ox monitor for COPD. When I feel faint or out of breath I use this and have seen a number of instances where my oxygen level was fine but heart rate was in 30's and 40's. Yesterday after exertion I felt unwell and pulse rate was between 29-44 for several minutes until I laid down.

I am wondering if the stress test is appropriate when it's not yet been determined whether my problem is one related to electrical activity in the heart? I had the feeling the doctor was not tuned in to what I was trying to say about having had bradycardia symptoms as well. I'd like to hear if anyone else has been through this scenario.
