The aim of this study was to determine whether P\u2010wave duration and presence of IAB before the implantation of a cardiac implantable electronic device (CIED) are associated with the presence of atrial high rate episodes (AHRE), during long\u2010term follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>380 patients (57% men; 75 \u00b1 10 years) were included. IAB was defined according to the International Consensus Criteria. AHRE was defined as an episode of atrial rate \u2265225\u00a0beats\/min with a minimum duration of 5\u00a0minutes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Documented paroxysmal AF before the implantation was present in 24% of the patients; 80% had hypertension and 32% structural heart disease. Mean P\u2010wave duration was 123 \u00b1 23\u00a0ms, and 39% of the patients had IAB (32% partial, 7% advanced). After a mean follow\u2010up of 18 \u00b1 12 months, 33% of the patients presented AHRE. Patients with AHRE had a P\u2010wave duration significantly longer (130 \u00b1 24\u00a0ms vs 119 \u00b1 21\u00a0ms; P\u00a0&lt;\u00a00.001) and a greater prevalence of IAB (53%\u00a0vs 32%; P\u00a0&lt;\u00a00.001). In a multivariate analysis, predictors of AHRE were: IAB (odds ratio [OR] 2.1; 95% confidence interval [CI] [1.3\u20133.4], P\u00a0&lt;\u00a00.001) and previous paroxysmal AF (OR 2.6; 95% CI [1.5\u20134.3], P\u00a0&lt;\u00a00.001). In patients without previous AF, the presence of IAB was also a significant predictor of AHRE (OR 3.1; 95% CI [1.8\u20135.5], P\u00a0&lt;\u00a00.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>IAB is a strong predictor of AHRE in patients with CIED.
