title: Reversible atrial fibrillation secondary to a mega-oesophagus.
abstract: BACKGROUND
  Atrial fibrillation (AF) is the most common cardiac arrhythmia, and it increases in prevalence with advancing age to about 5% in people older than 65 years.
  
  
  METHODS
  We present a rare case of atrial fibrillation secondary to a mega-oesophagus occurring in an 84-year-old Caucasian woman. The patient had a history of progressive dysphagia and the accumulation of food debris lead to mega-oesophagus.
  
  
  CONCLUSIONS
  The diagnosis was made by barium swallow and electrocardiogram; evacuations of 300 ml of the food debris lead to complete resolution of the arrhythmia. The possible aetiology leading to this AF is discussed.
