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 ...

When the atrial rate is greater than 100 beats per minute ... Brief atrial tachycardia is seen very commonly on ambulatory ECG monitoring in the elderly and is frequently asymptomatic.
