Atrial flutter
Def....atrial flutter is characterised by a regular rapid atrial rate of 250-350/min.where ventricles respond to every second,third or fourth heart beat (2:1,3:1 atrioventricular block).Causes
-Organic heart disease (ischaemic,rheumatic,congenital).
-pericarditis
-acute respiratory failure
-1st week following open heart
surgery.
Electrocardiographic feature
-characteristic flutter waves r seen as regular saw toothed waves F waves.
Management
-immediate conversion to sinus rhythm can be accomplished by direct current cardioversion or atrial pacing
-initial reduction of ventricular rate using digoxin.beta blockers or verapamil followed by conversion to sinus rhythm using quinidine.amiodarone.disopyramide.
-prevention of recurrences can be accomplished by quinidine.amiodarone.disopyramide or flecainide.
