Patients with atrial flutter, as with atrial fibrillation, tend to be older adults. In one study, the average age was 64 years. The prevalence of atrial fibrillation increases with age, as follows:

  • 25-35 years: 2-3 cases per 1000 population
  • 55-64 years: 30-90 cases per 1000 population
  • 65-90 years: 50-90 cases per 1000 population
