Atrial flutter is a type of supraventricular tachycardia caused by a re-entry circuit within the right atrium
The electrocardiogram (ECG) usually demonstrates a regular rhythm, with P waves that can appear sawtoothed (see the image below), also called flutter waves, usually best visible in lead II. The QRS complex is narrow if there is no aberrancy. Because the AV node cannot conduct at the same ...

Atrial Flutter ECG ReviewAtrial 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 is 400 to 600 bpm. ...
One of the major management decisions in atrial fibrillation (AF) (and atrial flutter) is determining the risk of stroke and appropriate anticoagulation regimen for low-, intermediate-, and high-risk patients. For each anticoagulant, the benefit in terms of stroke reduction must be weighed against...
Image: Learn the Heart The ventricular rate is frequently elevated; at rates above 150 bpm, it may be difficult to distinguish AF from atrial flutter, atrial tachycardia or atrioventricular nodal reentrant tachycardia (AVNRT). In this situation, administering adenosine will transiently slow the ventric...
(mostly paroxysmal), which is two-channel ECG signals each sampled at 250 samples per second with 12-bit resolution over a range ± 10 mV for 10 h. The rhythm annotation files were prepared manually. The rhythm annotations of types are atrial fibrillation (AF), atrial flutter (AFL), ...
