Like Remar said you are not being specific as to the max HR you are referring too. I can tell you that when my anxiety would spike (and I would stay in that "fight or flight mode for DAYS) my HR would stay elevated, typically in the 90s or so. I had to get my anxiety under control for help with the adrenaline
How high does your heart rate get? Is it never above the 80's? Normal resting heart rate is between 60 and 100. Sorry, I'm not really sure what your question is. Could you be more specific please.
