The differential for narrow complex tachycardia is extremely important as it is the most commonly seen abnormal EKG in the emergency department. It includes rhythms such as sinus tachycardia, AVnRT, AVRT, atrial flutter, ectopic atrial tachycardia (EAT), atrial fibrillation, atrial flutter, and multifocal atrial tachycardia (MAT).
