title: Pseudoatrial fibrillation during pacemaker interrogation: what is the mechanism?
abstract: BACKGROUND
  Normal pacemaker response to magnet and programmer is almost universal and helps to interpret basal rhythm.
  
  
  RESULTS
  In this report, we report an undescribed atypical magnet response due to an internal cross-talk with atrial oversensing during a specific part of interrogation, simulating atrial fibrillation.
