A 41‐year‐old woman with recurrent wide‐QRS tachycardia is reported. Electrophysiologic findings were consistent with the diagnosis of a preexcited atrioventricular nodal reentrant tachycardia due to a bystander nodo‐ventricular fiber. However, slow pathway ablation did not preclude tachycardia recurrence. A second electrophysiology study shed light on the correct mechanism and eventually a successful ablation was achieved.
