An atrial arrhythmia: The two top chambers of the 4chamber heart are called atria. The normal heartbeat is set off in sinus node, a concentrated bundle of heart cells that sets off the lub (contraction of atria) of the lub dub. Every single heart cell has the capacity to depolarize & set the chambers into contraction. Atrial fibrillation or flutter causes chaotic atrial contrctns. Ekg in flutter looks like a saw tooth.

Atrial flutter: This is a rapid regular atrial rhythm from 250-350 beats per minute roughly, it rarely conducts to the ventricles at 1:1. It is related to atrial fibrillation and is treated in a somewhat similar manner.
