Management of patients with atrial tachycardia: a clinical consensus statement of the European Heart Rhythm Association (EHRA) of the ESC, endorsed by the Heart Rhythm Society (HRS), the Asia Pacific Heart Rhythm Society (APHRS), the Latin American Heart Rhythm Society (LAHRS), and the Association for European Paediatric and Congenital Cardiology (AEPC)

Abstract

Atrial tachycardias (AT) represent an increasingly recognized cause of morbidity and mortality. Over the past decade, the mechanistic understanding and therapeutic concepts guiding AT treatment have undergone rapid progress. Catheter ablation has become the most effective therapy for maintaining sinus rhythm in patients with regular AT, while mapping and ablation concepts and technologies have improved significantly. Accordingly, international cardiac electrophysiology professional societies aimed at outlining best practices on the management of regular AT, with a special focus on indications, timing, and technical aspects of AT mapping and ablation. After reviewing and discussing available evidence, including a systematic literature review and meta-analysis, an expert writing group summarized current knowledge and practice and has proposed strategies in the here outlined 10-Point Plan for SMART-AT care (Standardized Management and Ablation Roadmap for Treatment of Patients with Atrial Tachycardia).
