Atrial flutter occurs when a “reentrant” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute; the atrial rate in ...

Atrial fibrillation (AF) is characterized by rapid and irregular activation of the atrium, for example, 400–600 pulses of the atrium muscular wall per minute in humans. The occurrence of AF increases ...
