Typical atrial flutter rotates around tricuspid annulus and uses the crista terminalis and sometimes sinus venosa as the boundary. The IVC-tricuspid isthmus is a slow conduction zone and the …

Oct 8, 2024 · Atrial flutter is a form of supraventricular tachycardia caused by a re-entry circuit within the right atrium. The length of the re-entry circuit corresponds to the size of the right …

Electrophysiological studies have defined multiple mechanisms of tachycardia, both re-entrant and focal, with varying ECG morphologies and rates, authenticated by the results of catheter …

Mar 11, 2025 · Atrial flutter is a common arrhythmia that involves a reentrant circuit in the atria, leading to rapid but organized atrial contractions. The condition can have a significant impact …

Jun 14, 2024 · 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.

Atrial flutter is characterized by a sudden-onset (usually) regular abnormal heart rhythm on an electrocardiogram (ECG) in which the heart rate is fast.

Atrial flutter is a rapid regular atrial rhythm due to an atrial macroreentrant circuit. Symptoms include palpitations and sometimes weakness, effort intolerance, dyspnea, and presyncope.

May 1, 2002 · Classical atrial flutter, now called typical and reverse typical atrial flutter [7], is well recognized to be due to a macro-reentrant mechanism, in which the reentrant wave front …

Common or typical right atrial flutter is attributed to a wavefront of electrical propagation encircling the tricuspid valve annulus, bounded anteriorly by the annulus and posteriorly by the inferior …

Sep 19, 2025 · There is frequently 2:1 conduction across the atrioventricular (AV) node, meaning that every other atrial depolarization reaches the ventricles. As a result, the ventricular rate is …
