AV conduction in the setting of atrial flutter can be variable and dependent on atrial rate, often 2 : 1. Typically electrical cardioversion or pacing is required to terminate the arrhythmia. View chapterExplore book Cardiac Diseases David M. Greer, ... Karen L. Furie, in Stroke (Sixth...
Atrial flutter (AFL) is characterized by rapid atrial activation with atrial rate usually between 240 and 320 beats per minute with a variable ventricular response depending on the status of AV conduction. One has to keep in mind that on occasion, atrial rate may be slower due to the use ...

(ECG) is not always AF. It is necessary to consider and exclude other types of irregular rhythm disturbances, including atrial or ventricular ectopy, atrial tachycardia, or atrial flutter (Figure 1) with variable AV conduction, multifocal atrial tachycardia (Figure 2), and wandering atrial ...

The conducted ventricular rhythm is also usually regular but may become irregular, often at higheratrialrates because of variable conduction through the AV node, thus producing conduction patterns such as 2:1, 3:1, andWenckebachAV block. The P wave morphology as observed on the ECG may give ...
