We define AFL as an arrhythmia with a macroreentrant circuit (>2 cm) distinct from focal atrial tachycardias (or small circuit reentry) with subsequent centrifugal spread. Symptoms are typic- ally related to the rate of ventricular response. Thin wires are used to send energy to destroy the tiny areas of heart tissue that are causing atrial flutter. In this chapter, we will review recent advances in our understanding of AFL mechanisms, its heterogeneous nature, and treatment. Typical atrial flutter is a common atrial tachyarrhythmia. Catheter ablation to stop atrial flutter. Atrial fibrillation is a common and harmful arrhythmia, not only for thromboembolic risk but also for symptoms, quality of life, hospitalization rate, and risk of death. AFL often occurs in the context of structural heart disease (e.g., valvular, ischemic heart disease, cardiomyopathy) and may also manifest during acute disease process (e.g., sepsis, myocardial infarction). It results from organised electrical activity in which large areas of the atrium take part in the re-entrant circuit. We define AFL as an arrhythmia with a macroreentrant circuit (>2 cm) distinct from focal atrial tachycardias (or small circuit reentry) with subsequent centrifugal spread.ĪB - Atrial flutter (AFL) is one of the most common cardiac arrhythmias in humans, afflicting ∼0.19 million people in the United States in 2005 its prevalence is expected to increase to 0.44 million by 2050 because of the aging population. Typical atrial flutter (anticlockwise cavotricuspid isthmus-dependent atrial flutter) is a macro re-entrant atrial tachycardia with atrial rates usually above 250 bpm up to 320 bpm. In this chapter, we will review recent advances in our understanding of AFL mechanisms, its heterogeneous nature, and treatment. Atrial flutter (AFL) is one of the most common cardiac arrhythmias in humans, affecting approximately 190,000 people in the United States in 2005 its prevalence is expected to increase to 440,000 by 2050 because of the increasingly older population. N2 - Atrial flutter (AFL) is one of the most common cardiac arrhythmias in humans, afflicting ∼0.19 million people in the United States in 2005 its prevalence is expected to increase to 0.44 million by 2050 because of the aging population. Typical atrial flutter (AFL) is a type of macroreentrant atrial tachycardia (AT) that uses the CTI as an essential part of its circuit.
