How is atrial tachycardia characterized?

Atrial tachycardia is characterized by a rapid heartbeat that originates specifically from the atria, typically ranging between 150 to 200 beats per minute. This condition occurs when an abnormal electrical impulse causes the atria to beat faster than usual. Understanding the origin and rate of the heartbeat is crucial in distinguishing atrial tachycardia from other types of tachycardia, such as ventricular tachycardia, which originates from the ventricles and involves different clinical implications. The rate and regularity of the heartbeat also help differentiate it from other rhythm abnormalities. A normal heartbeat pattern does not indicate atrial tachycardia, nor does an irregular or slow heartbeat—both of which are inconsistent with this specific condition. Hence, the defining feature of atrial tachycardia is its distinct origin in the atria and the rapid heart rate observed.
