I'm taking Atenolol, but have been taking it for over a year, and not until about two weeks ago did the slow heart rate begin. This was noted on an autonomic test I had done. Dear Ellen, Normal heart rate is between 50 and 90. A resting rate of 60, especially on beta blockers is nothing to be concerned about especially if you are not having any symptoms. The vagus nerve keeps the heart from going to fast.
Adrenergic function makes the heart go faster.
Your adrenergic function is normal and your vagus function is slightly reduced by this test. Information provided here is for general educational purposes only.
