What is the typical heart rate associated with atrial flutter?

• A. 60 to 100 beats per minute
• B. 100 to 150 beats per minute
• C. 240 to 340 beats per minute
• D. More than 340 beats per minute

Answer: (C)

Atrial flutter is characterized by a rapid reentrant circuit typically located in the right atrium. The hallmark feature of atrial flutter is the atrial rate, which usually falls within a specific range due to the distinct mechanism of the arrhythmia. The typical heart rate associated with atrial flutter ranges between 240 and 340 beats per minute. This elevated heart rate results from the automative nature of the atrial electrical impulses, which can lead to a consistent and organized contraction of atrial tissue. In contrast, the other heart rate ranges mentioned do not represent the typical state of atrial flutter. Rates of 60 to 100 beats per minute are commonly seen in normal sinus rhythm, while 100 to 150 beats per minute could relate to other forms of tachycardia, such as atrial tachycardia or supraventricular tachycardia, rather than atrial flutter. Heart rates exceeding 340 beats per minute might suggest a different and more chaotic arrhythmia, which is beyond the organized rhythm typical of atrial flutter. Thus, the specified range of 240 to 340 beats per minute accurately reflects the typical heart rate for this condition.
