Atrial Flutter

Although the rate is 140 bpm, it is possible to clearly identify the P wave, QRS complex and T wave.

Notice how the flutter waves are clearly defined like the teeth of a saw. There are 4 flutter waves between each QRS complex and the rate is 75 bpm. (4 large squares divided into 300)
Atrial Flutter with 2:1 Block

The rhythms above are still atrial flutter but the rate is now 150 bpm. Too fast to analyse if the rhythm is regular. But because the rate is 150 bpm it is likely to be atrial flutter with 2:1 block.
