The Norwegian Exercise in Atrial Fibrillation Trial

150-300 minutes of moderate intensity activity (55-75% of maximum heart rate in sinus rhythm or RPE 12-13 on the Borg Scale) or 75-150 minutes of vigorous intensity activity (75-90% of maximum heart rate or 14-16 on the Borg Scale) per week, or an equivalent combination of both, according to current general recommendations, including also those with established CVD. To maximize the potential for improvements in cardiorespiratory fitness, we encourage that at least 40-60 minutes per week (i.e. 2 sessions á 20-30 minutes) should be of vigorous intensity.

Standard management according to usual practice at the respective participating centers, including medical therapy as per guidelines. Prior to randomization all will be provided an ICM (Confirm RX™). The UC group will receive information about general PA recommendations as per guidelines at study enrollment. No further supervision is given.
