Atrial flutter is commonly described as:

1. Consistent heart rhythm

2. Rapid heartbeat

3. Irregular beating of the atria

4. Normal atrial contraction

The correct answer is: Irregular beating of the atria

Atrial flutter is characterized by a specific type of abnormal heart rhythm wherein the atria, the upper chambers of the heart, beat in a rapid and organized manner. This leads to a scenario where the atria may contract quickly but in a regulated form, often around 240 to 340 beats per minute. However, rather than being completely chaotic, the contractions are recognized as a fluttering rhythm that can create a distinct pattern observable on an electrocardiogram (ECG). The key aspect of atrial flutter is this organized but rapid beating of the atria, which differentiates it from conditions that exhibit more chaotic or disorganized electrical activity. Such regulation distinguishes it from irregular rhythms seen in other arrhythmias, highlighting why the rhythmic aspect of atrial flutter is an essential component of its definition. In contrast, options describing consistent heart rhythm or normal atrial contraction do not accurately represent the nature of atrial flutter, as neither aligns with the rapid and fluttering pattern of activity observed. Similarly, while rapid heartbeat is a feature of atrial flutter, the primary descriptive quality is the irregular beating pattern of the atria, which captures the essence of this arrhythmia more accurately.
