Abstract

Here, we discuss mapping of an atrioventricular reciprocating tachycardia (AVRT) using color-coding and a coherence module of the CARTO^® mapping system (Biosense Webster, Diamond Bar, CA, USA). AVRT is a reentry tachycardia and, when the atrial exit site of the arrhythmia circuit was mapped in this case, it appeared to have a focal centrifugal activation pattern as depicted by coherent mapping.

Keywords: AVRT; Ablation; coherent; mapping; three-dimensional.
