What is the typical heart rate range for Atrial Flutter?

• A. 60 to 100 beats per minute
• B. 100 to 160 beats per minute
• C. 240 to 340 beats per minute
• D. 150 to 250 beats per minute

Answer: (C)

The most accurate heart rate range for Atrial Flutter typically falls between 150 to 250 beats per minute. This elevated heart rate occurs because Atrial Flutter is characterized by a rapid reentrant circuit within the atria, often leading to a consistent rhythm that is faster than normal but less chaotic than Atrial Fibrillation. The typical "sawtooth" pattern seen in Atrial Flutter, especially observed in EKG readings, correlates with this range, reflecting the rapid atrial contractions that define the arrhythmia. While the other ranges provided may pertain to different conditions or heart rhythms, they do not represent the hallmark characteristics of Atrial Flutter, making the 150 to 250 beats per minute range the most representative of this particular arrhythmia. Understanding this helps in differentiating Atrial Flutter from other atrial arrhythmias, which can have significantly different heart rate profiles.
