Incidence of Atrial Fibrillation in African Americans post Atrial Flutter Ablation.

Background: African Americans have a lower incidence of atrial arrhythmias both atrial fibrillation (AF) and atrial flutter (AFL) despite having a greater number of traditional risk factors. The incidence of atrial fibrillation after cavotricuspid isthmus (CTI) ablation in patients with typical AFL is markedly increased approaching 40% in some studies. It is unknown if African Americans specifically have a similar rate of increased AF after CTI ablation for typical AFL.
