Atrial tachycardia is characterized as a rapid arrhythmia that is typically regular and can occur in bursts or may be sustained. This means that during episodes of atrial tachycardia, the heart's atria exhibit rapid electrical impulses, leading to a consistent rhythm, which is why it's described as regular.

The term "bursts" refers to the fact that atrial tachycardia can appear suddenly and may resolve on its own after a certain duration, making it paroxysmal in nature. However, it can also persist over time, leading to a sustained form of the arrhythmia. This duality in pattern—intermittent and sustained—is a key feature of atrial tachycardia, and it distinguishes it from other types of rapid arrhythmias that may be irregular or exhibit different patterns of occurrence.

Understanding these characteristics is crucial for the diagnosis and management of atrial tachycardia, as it helps clinicians determine the best treatment strategies for patients experiencing this type of arrhythmia.
