I would think it's a problem and too low as you are in the throes of an ED. I'm pretty athletic, and my resting heartrate is generally around 52-55 bpm. During vigorous activity, it's up to 150 bpm, but that's really vigorous, like jogging in the heat. I really don't see how your treatment team is not getting you medical help for your ED at this point. What are they waiting for?
