At a glance
- Macro-re-entrant atrial tachycardia with an atrial rate of about 250 to 350/min, usually conducted 2:1 to give a ventricular rate near 150/min.
- Typical flutter runs around the tricuspid annulus through the cavotricuspid isthmus (CTI) and is cured by CTI ablation in over 90%.
- It shares causes, stroke risk and anticoagulation rules with atrial fibrillation, and the two often coexist.
