![]() 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. In this chapter, we will review recent advances in our understanding of AFL mechanisms, its heterogeneous nature, and treatment. 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). Sometimes a medical procedure called an ablation is needed. 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. An ablation is a medical procedure that is done to correct certain heart rhythm problems such as atrial flutter. They slow the heart rate and control the flow of beat now signals that regulate the heartbeat. ![]() ![]() 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.
