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.

At times it is difficult to distinguish atrial fibrillation from atrial flutter on the ECG. This example shows coarse "fibrillatory waves" in the setting of atrial fibrillation. This are of ...

Lab tests show an increased ... The two atrial waveforms have the same morphology and occur at a regular rate of 300 beats/min. Therefore, the rhythm is atrial flutter with 2:1 AV block.

It is characterized by 'saw-tooth' flutter waves in inferior electrocardiogram leads. Given the large excitable gap associated with typical atrial flutter, antiarrhythmic medications may stabilize ...

The FDA submission is backed by robust data from the VALID-ECG pivotal study ... Arrhythmias evaluated include sinus rhythm, atrial fibrillation, atrial flutter, and sinus with premature ...
