Atrial flutter is a supraventricular tachydysrhythmia believed to arise from electrophysiologic disturbances in the atria. It tends to be an unstable rhythm and is usually associated with intrinsic cardiac or pulmonary disease or adverse extrinsic influences on the heart. It is due to either a re...
Atrial flutter with 2:1 AV block can be difficult to distinguish from other, regular narrow-complex tachycardias because one of the flutter waves may be concealed within the QRS complex; the rhythm may be mistaken for sinus tachycardia with first-degree AV block. Negative flutter waves on the...

Atrial flutter is a cardiac arrhythmia characterized by atrial rates of 240-400 beats/min, usually with some degree of atrioventricular (AV) node conduction block (eg, 2:1 or 3:1 block). Approximately 60% of patients with atrial flutter have coronary artery disease (CAD) or hypertensive ...

Because the AV node cannot conduct at the same rate as the atrial activity, some form of conduction block is often seen, typically 2:1 (most common), 3:1, or 4:1. This block may also be variable and cause atrial flutter to appear as an irregular rhythm. Twelve-lead ECG showing ...
