What is the typical heart rate associated with atrial flutter?

The typical heart rate associated with atrial flutter is generally characterized by a rapid atrial rate of 250-350 beats per minute. This arrhythmia results from a reentrant circuit in the atria, typically in the right atrium, leading to the rapid and regular contracting of the atria. While the ventricular response can vary depending on factors such as conduction through the atrioventricular (AV) node, the hallmark of atrial flutter is the atrial rate falling within that range.

When considering the other heart rate ranges provided, they tend to represent different situations or types of arrhythmias. For instance, 60-100 beats per minute is considered normal sinus rhythm. Heart rates of 100-120 beats per minute might indicate mild tachycardia, which is not specifically indicative of atrial flutter. Rates of 120-180 beats per minute could be associated with conditions like atrial fibrillation with a rapid ventricular response, but again, these do not specifically define atrial flutter's typical atrial rate. Thus, recognizing the fast and regular rhythm of atrial flutter at 250-350 beats per minute is crucial for accurate diagnosis and management.
