Treatment of atrial flutter

Extract

• After atrial fibrillation, atrial flutter is the next most common and significant atrial arrhythmia.
• The regular sawtooth flutter waves (F waves) of typical atrial flutter can be seen in ECG leads II, III, and aVF (picture 1). The atrial rate is 240–350/min.
• Antiarrhythmic drugs have proved not to be very effective and, in some cases, even dangerous. Catheter ablation has therefore superseded antiarrhythmic drugs in the prophylactic treatment of typical atrial flutter.
• Flecainide is commonly used in the treatment of lone atrial fibrillation, but it must be avoided in atrial flutter due to the risk of proarrhythmia (1:1 atrial flutter).
