However, the effectiveness of CA amongst the subset of patients with tachycardia\u2010induced cardiomyopathy (TIC) remains poorly defined.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>In a retrospective analysis we compared outcomes of first\u2010time CA for persistent AF in a cohort of patients with previously diagnosed TIC (n\u2009=\u200945; age 58\u2009\u00b1\u20098 years; 91% male) to those with structurally normal hearts (non\u2010TIC; n\u2009=\u2009440; age 55\u2009\u00b1\u20099 years; 95% male). TIC was defined as an impaired ventricular function (left ventricular ejection function [LVEF] &lt;50%), which was reversed after the treatment of HF. We compared atrial arrhythmias (AAs) recurrence after the CA in the TIC and non\u2010TIC cohorts. In the TIC group, LVEF improved from 35.8%\u2009\u00b1\u20098.1% to 57.5%\u2009\u00b1\u20098.3% after treatment of HF. During 3.3\u2009\u00b1\u20091.5 years follow\u2010up, AAs\u2010free survival after CA was significantly higher in the TIC group as compared with the non\u2010TIC group (69% vs 42%; <jats:italic>P<\/jats:italic>\u2009=\u2009.001), despite a comparable CA strategy between the two groups. In multivariable analysis, absence of HF with TIC, longer AF duration, and complex fractionated atrial electrogram ablation were independent predictors of arrhythmia recurrence (OR, 1.02; 95% CI, 1.01\u20101.03; <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.01; OR, 0.40; 95% CI, 0.20\u20100.79; <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.01 and OR, 2.29; 95%CI; 1.27\u20104.11; <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.01, respectively). In addition, the outcome after the last procedure was superior in the TIC cohort (89% vs 72%; <jats:italic>P<\/jats:italic>\u2009=\u2009.03) with fewer CA procedures as compared with the non\u2010TIC cohort (1.3\u2009\u00b1\u20090.5 vs 1.5\u2009\u00b1\u20090.7; <jats:italic>P<\/jats:italic>\u2009=\u2009.01).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Persistent
