An ECG strip shows the presence of atrial flutter, which involves rapid contraction of the atria. Atrial flutter is indicated by a very rapid (250 to 350 beats per minute) rate and a "saw tooth" pattern. In this case, the ventricular (QRS) rate is also fast. A normal ECG strip is shown at the bottom for comparison.
