Prevalence of Atrial Flutter

Atrial flutter is a common dysrhythmia in older patients (Table 1) and has similar causes to atrial fibrillation. A rare cause is digoxin toxicity and this should always be considered before treatment.

Many patients have episodes of both flutter and fibrillation, and patients with atrial flutter often progress to atrial fibrillation with advancing age or if left untreated. It is unusual for patients to remain in atrial flutter long-term.

Male: Female ratio is 2:1.
