A 23‐year‐old gentleman presented with a history of palpitations. The 12‐lead electrocardiogram showed no manifest ventricular pre‐excitation. Echocardiogram was within normal limits. A retrograde study showed concentric activation of the atrium with decremental conduction. Atrial pacing from right atrial free wall showed progressive pre‐excitation. No anterograde nodal duality was documented.
