Different rotation activation pattern (RAP) sites with good pacemap score were identified by activation mapping with both last deflection and peak frequency annotations. These two RAP sites were considered to be the critical ablation targets of ventricular tachycardia in cardiac sarcoidosis, which led to successful ablation without an extensive lesion.
Keywords: cardiac sarcoidosis; isochronal late activation mapping; last deflection annotation; peak frequency annotation; ventricular tachycardia.
