What Is Your Resting Heart Rate? in Dysautonomia Discussion Posted August 10, 2012 · Report reply Since being on a beta blocker, my resting h/r is low 50's to sometimes 40's. A few times on cardionet, I was captured at 27. And to think that two years ago my resting was above 100. Been lowering the beta (acebutolol) to every other day at the smallest dose, but heart rate stays the same. It did come back up when I went three days without out and worked out.Got to 103. But the beta blocker does help with the surges.
