Background: Atrial fibrillation is the most common clinically significant cardiac arrhythmia. It occurs when a diffuse and chaotic pattern of electrical activity in the atria suppresses or replaces the normal sinus mechanism. This disorder is a major cause of morbidity, mortality, and health care expenditure. Case Presentation: In this article, we will present a rare case of a 93-year-old men who was admitted with atrial fibrillation secondary to megaesophagus that was reversible to sinus rhythm after dilation and removal of food debris from the esophagus. Conclusion: The megaesophagus can lead to atrial fibrillation by compression of the left atrium, which is reversible after dilatation sessions and the evacuation of food debris in the esophagus.
