Atrial flutter is an extremely common condition, especially in older patients. In this, the electrical circuit revolves round and round in the right atrium at the rate of 250-300 beats per minute.

In atrial fibrillation (AF), the sinus node is no longer regulating the electrical activation of the atria. Instead, chaotic, swirling wavefronts of electrical activation pass through the atria.
