This block may also be variable and cause atrial flutter to appear as an irregular rhythm. Twelve-lead ECG showing atrial flutter with variable block. View Media Gallery Atrial flutter can arise from conditions that lead to atrial dilatation. These include chronic left-sided congestive heart ...
Atrial flutter is a type of supraventricular tachycardia caused by a re-entry circuit within the right atrium
A 67-year-old man without prior heart disease presented with atrial flutter, with a 12-lead electrocardiogram (ECG) suggestive of typical atrial flutter. The patient underwent electrophysiology study and was found to have atypical atrial flutter, with entrainment mapping indicating likely left-sided ...
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. ...
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...
