Epidemiology
-
-
-
-
Often associated with atrial fibrillation and frequently require a similar initial therapeutic approach
Treatment
Catheter ablation - creating a conduction block to try a restore rhythm and block offending re-entrant wave
IV Amiodarone to restore sinus rhythm and use a beta-blocker e.g. Bisoprolol to suppress further arrhythmias
Electrical cardioversion but anticoagulant before e.g. low molecular weight heparin e.g. Enoxaparin or Dalteparin if acute i.e. atrial flutter started less than 48 hours ago

Diagnosis
ECG
Regular saw tooth-like atrial flutter, waves (F waves) between QRS complexes due to continuous atrial depolarisation
Note: if F waves are not visible then they may be able to be unmasked by slowing atrioventricular conduction by carotid sinus massage or IV adenosine (AVN blocker)
