What is the range of heart rate for Atrial Flutter?

Atrial flutter typically presents with a rapid heart rate, commonly ranging from 250 to 350 beats per minute. This is due to the presence of a reentrant circuit within the atria, leading to a rapid and regular atrial contraction. In this arrhythmia, the atrial rate is generally more organized than in atrial fibrillation, allowing it to sustain this particular heart rate.

The rapid activation of the atria can result in variable ventricular responses depending on the atrioventricular (AV) node's conduction properties. However, the defining characteristic of atrial flutter is its atrial rate consistently being within that 250 to 350 bpm range, which distinguishes it from other arrhythmias. Other heart rate ranges listed do not accurately reflect the typical atrial rate in atrial flutter.
