Atrial flutter is characterised by a regular, rapid atrial rate of 250-350 per minute, where ventricles respond to every second, third or fourth beat. Some common causes are Organic heart diseases, Pericarditis, Acute respiratory failure and First week following open heart surgery. Electrocardiographic feature are characterised by flutter waves are seen as regular saw-toothed waves. Atrial flutter can be managed by immediate conversion to sinus rhythm can be accomplished by direct current cardio version or atrial spacing and also initial reduction of ventricular rate using digoxin, beta-blockers or verapamil followed by conversion to sinus rhythm using quinidine, amiodarone, disopyramide or flecainide.
