What is the ideal resting heart rate with af?

Same: Same as normal heart rate, 60 to 100 BPM although up to 110 BPM would be ok based on 2011 guidelines.

60-100: The resting heart rate ideally should be well below 100 beats per minute, which is similar to a heart rate in normal rhythm. There may be some leeway with regard to rate depending on various other factors such as other illnesses and how recently the diagnosis was made.
