A patient with Brugada syndrome implanted with subcutaneous implantable cardioverter defibrillator (S‐ICD) had oversensing episodes treated with S‐ICD shocks. Comparable artifacts were not evocable with S‐ICD pocket manipulation. The fluoroscopy excluded S‐ICD macroscopic damage. The device extraction revealed undamaged pulse generator and connector, but the lead was inappropriately tunneled under the sixth rib. Then the S‐ICD malfunction was due to lead microscopic damage caused by the lead rubbing the rib surface.
