Guidelines suggest a resting rate below 80, and a rate below 115 on exercise. For many who don’t exercise hard, this may well be achievable without medication. This will include those unaware they have AF, either without symptoms or who accept how they feel as normal when getting older.
The Race-2 trial from 2010 challenged these guidelines and concluded that so called “ lenient” rate control with a target resting rate below 110, was “non-inferior” to “strict” control as recommended.
I was looking in to this, because I was getting fed up with the side effects from Nebivolol which for me have been only marginally less than Bisoprolol. I weaned myself off the Nebivolol and my resting rate is between 70-80. I have more energy and nap less: my exercise tolerance is much better.
I like to exercise reasonably energetically in the gym, and often push my rate to 130 and don’t see that as a problem.
I don’t suggest anyone else in my situation should do this, but it may be worth discussing with your GP.
The RATE-AF trial from Birmingham UK, revisits this and reports later this year.
