What is the typical atrial tachycardia rate?

Explanation:
In atrial tachycardia, an ectopic atrial focus fires rapidly, so the atrial rate becomes brisk and regular. The typical range for this paced atrial rhythm is about 140–250 beats per minute. This range helps distinguish it from other tachycardias: normal sinus rhythm is 60–100 bpm, sinus tachycardia usually up to around 160 bpm, and atrial flutter typically around 250–350 bpm. The actual ventricular rate depends on how the AV node conducts those impulses, but the atrial rate placing within 140–250 bpm is characteristic of atrial tachycardia.
