Oct 8, 2024 · Higher-degree blocks can occur — usually due to medications or underlying heart disease — resulting in lower rates of ventricular conduction, e.g. 3:1 or 4:1 block. Atrial flutter …

Typical atrial flutter is due to a large reentrant circuit involving most of the right atrium and requires conduction between the orifice of the inferior vena cava and the annulus of the …

An electrocardiogram showing atrial flutter in which varying ratios of AV conduction and the cyclical recurrence of varying QRS morphologies are observed is presented.

Jun 20, 2025 · Here, we present a case of atrial flutter with a marked SVR in a patient without exposure to AV nodal inhibitors, highlighting the need for comprehensive evaluation and …

Oct 10, 2013 · The P waves, also called flutter waves, march out regularly at a rate of around 300/minute, which is typical of atrial flutter. The conduction ratio is variable, and the intervals …

Nov 4, 2024 · Sometimes, variable conduction may occur with alternating or seemingly random patterns of 2:1, 3:1, 4:1, or other conduction patterns, again due to varying levels of block in …

Dec 10, 2024 · Atrial flutter, in the typical form, is characterized electrocardiographically by flutter waves, which are a saw-tooth pattern of atrial activation, most prominent in leads II, III, aVF, …

This article discusses atrial flutter with emphasis on ECG diagnosis, clinical features, causes and management. Current guidelines are also presented.
