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...
On ECG, the hallmark pattern is “saw-toothed” flutter waves, which are best viewed in leads II, III, and V1. The atrial rate is on average approximately 300 atrial bpm.3 Since the AV node cannot respond this quickly, there is an AV block that can present as a 2: 1, 3: 1, or...
Atrial flutter is a type of supraventricular tachycardia caused by a re-entry circuit within the right atrium

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. ...
heart condition. May be present: palpitations, dizziness, anxiety, faintness, shortness of breath, attacks ofangina pectoris(especially in form with atrioventricular block 2 / 1) especially if it is a severe cardiomyopathy. Atrial flutter with ventricular rate of 75 beats / minute may be ...
(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), ...
