Hi Steph, I also have a very low resting HR. Usually between 45-55. I used to run all the time and thought it was that at the time. My LLMD thinks it could be thyroid or low metabolism. Have you been checked for either one? I know this stupid illness effects the heart. Ironically, last yr as I was trying to find out what was wrong with me, I found out I have a hole in my heart from birth! Has your cardio doc run many tests to rule out other things?
