Transient atrial fibrillation in a patient with acute ureterolithiasis

A 34-year-old woman with symptoms associated with a confirmed ureteral calculus was found to be in atrial fibrillation on arrival at the emergency department. When her symptoms had improved, it was noted that the atrial fibrillation had reverted spontaneously to a sinus rhythm. Subsequent evaluation did not reveal a common etiology of the atrial fibrillation. Transient atrial fibrillation has been associated with many diverse conditions. It has not been previously reported in association with acute ureterolithiasis.
