About prevalence and incidence statistics:

The term 'prevalence' of Atrial Fibrillation usually refers to the estimated population of people who are managing Atrial Fibrillation at any given time. The term 'incidence' of Atrial Fibrillation refers to the annual diagnosis rate, or the number of new cases of Atrial Fibrillation diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence.
