Atrial Tachycardia

Atrial flutter occurs from a reentrant circuit around the tripcuspid valve in the right atrium. It is an organized rhythm that is generally characterized by an atrial rate around 300 bpm, and a heart rate around 150 bpm. Consider 2:1 flutter in any tachycardia with a ventricular rate of 125 to 200 bpm, most commonly close to 150 bpm.
