We report a case of atrioventricular (AV) block diagnosed 28 years ago compensated by a functional accessory pathway. During follow‐up, the accessory pathway conduction properties at rest deteriorated while the refractory properties were unchanged. At 46 years, the patient became symptomatic from bradycardia and a dual‐chamber pacemaker was implanted. Although rare, concealed AV block due to an accessory pathway has to be recognized before radiofrequency ablation.
