Atrial Flutter - ECG
Atrial flutter is a rhythm disorder usually associated with tachycardia, in which we find the “sawtooth” flutter waves that are typically well seen in leads II, III, aVF. The QRS complexes are short.

that are best visible in leads II, III, aVF (red)
Conclusion: In atrial flutter we use a similar approach as in atrial fibrillation. The flutter is relatively sensitive to the electrical cardioversion.
