What is atypical atrial flutter

The Re-entrant Mechanism Typical flutter is the type of MRT most frequently found in the clinical setting. The mechanism is a large re-entrant circuit contained in the right atrium (RA) with passive activation of the left atrium (LA).22 May 2017

Atypical atrial flutter is caused by scarring on the left side of the heart from prior heart surgeries, previous procedures, or heart disease . The scarring can stretch and injure the upper heart chamber, leading to problems such as heart failure or valvular heart disease.

INTRODUCTION. Atrial flutter (AFL) is an abnormal cardiac rhythm characterized by rapid, regular atrial depolarizations at a typical atrial rate of 250 to 350 beats per minute . There is frequently 2:1 conduction across the atrioventricular (AV) node, meaning that every other atrial depolarization reaches the ventricles …24 Şub 2021

Abstract. Atrial fibrillation (AF) is a common and refractory arrhythmia. Prevalence of AF increases with age. Asymptomatic AF is a state of asymptomatic episodes of arrhythmia and its exact prevalence remains unknown. Ablation and therapy with antiarrhythmic agents may predispose to asymptomatic AF.

Although atypical atrial flutter is characterised by a wavefront not travelling around the tricuspid annulus , it can take on many forms. Similarly, in typical atrial flutter, cycle arrhythmia, scarred atria, concomitant circuits, high and irregular ventricular rate responses can render diagnosis difficult.6 Mar 2013
