What is the typical atrial rate range for Atrial Flutter?

Atrial flutter is characterized by a rapid reentrant circuit in the atria, which leads to an organized, repetitive electrical activity in the atrial chambers. The typical atrial rate in atrial flutter ranges from 240 to 340 beats per minute. This is a well-established hallmark of the condition, distinguishing it from other atrial arrhythmias.

The atrial rate being in the range of 220 to 350 beats per minute is indicative of how the atrial electrical activity is conducted. In atrial flutter, the atria contract rapidly but can still present a regular rhythm, unlike atrial fibrillation, which is more chaotic. Understanding this specific range assists clinicians in identifying the condition and determining appropriate management strategies.

Other rates indicated by the options are not representative of atrial flutter. The ranges below 220 beats/min are generally associated with other types of arrhythmias, such as normal sinus rhythm or atrial fibrillation, rather than the unique fast yet organized rhythm of atrial flutter.
