Hi Jacob,
You need to ask your doctor about ordering a CTA Heart (it gives a picture of your heart in detail. I kept knocking on doctor doors until somebody listened to me. I went to a cardiologist concerning my afib and he ordered a Nuclear Med scan and called me regarding the " normal results"-per cardiologist, I asked for a CTA Heart scan and he stated that I didn't need one. He said to f/u with him in a year, I had a brain stem stroke exactly 2 weeks later.
