Atypical atrial flutter originates from the left atrium or areas in the right atrium, such as surgical scars, and has a variable appearance on ECG in regards to the flutter waves.

During the times of lesser conduction on this ECG, the flutter waves are more apparent. The atrial rate is organized at a rate of about 300 beats per minute. The P waves are negatively deflected ...
