Abstract

Atrial echo beats due to a dual‐atrioventricular nodal pathway are a possible cause of fluctuating tachycardia in cycle length (CL) but have not been reported so far. Here, we present a case of an 82‐year‐old man with symptomatic atrial tachycardia (AT), which was accompanied by periodic fluctuations in atrial sequence at the coronary sinus. Electrophysiological study (EPS) for atrioventricular conduction and three‐dimensional (3D) electro‐anatomical mapping system explained that the mechanism of periodic fluctuations was due to atrial echo beats through a dual‐atrioventricular nodal pathway.
