Aerobic Interval Training in Patients With Atrial Fibrillation

Aerobic Interval Training in Patients With Paroxysmal or Persistent Atrial Fibrillation

The purpose of this study is to determine the effect of aerobic interval training in patients with paroxysmal or persistent atrial fibrillation, especially to see if the burden of atrial fibrillation and symptoms are reduced.

Long term endurance sport practice is associated with a higher incidence of atrial fibrillation. Moderate/light physical activity seems to be associated with a lower incidence. The underlying mechanisms are uncertain. In order to examine the effect of training in this population, the investigators will perform a randomised controlled study with aerobic interval training in patients with paroxysmal/persistent atrial fibrillation.

Inclusion Criteria:

• Patients with paroxysmal or persistent atrial fibrillation, that are able to perform aerobic interval training.

Exclusion Criteria:

• Performing high intensity training (pulse >90% of max) for more than 2 times a week.
• Moderate intensity training more than 30 min, more than 3 times a week
• Previous open heart surgery
• EF <40%
• Significant aorta stenosis
• Mitral insufficiency, >gr. 2
• Pacemaker
• Earlier coronary intervention and not complete revascularization
