Atrial Flutter

Atrial flutter, or Intra-atrial re-entry tachycardia (IART) is similar in many ways to atrial fibrillation. Unlike fibrillation, however, atrial contractions are more coordinated and the pulse tends to be regular. It is usually associated with heart enlargement, tachycardia/bradycardia syndrome, electrolyte disorder, congenital heart defects or in patients who have undergone heart surgery.

A complete cardiovascular evaluation is indicated as well as attempting to terminate the atrial tachycardia. Electrocardioversion, medications and endocardial catheter ablation are most commonly used. Recurrent atrial flutter is not rare, even after successful acute treatment. The incidence of recurrent atrial flutter usually depends on the underlying cause and risk factors. Atrial flutter may be associated with stroke, heart failure, palpitations, dizziness, fainting, fatigue and shortness of breath. Sudden death is rarely seen, especially in patients with otherwise normal hearts.
