An unusual case of supraventricular arrhythmia.

This case report describes the occurrence of a supraventricular arrhythmia in a patient with a large epiphrenic oesophageal diverticulum. The arrhythmia was precipitated by meals and was thought to result from pressure effects on the left atrium. Medical therapy did not control the arrhythmia. Excision of the diverticulum combined with oesophageal myotomy resulted in a dramatic relief of symptoms.
