title: Recurrent syncope following radiation therapy.
abstract: This case report describes a 51-year-old man who presented with syncope. His electrocardiogram showed an abnormally long pause and the electrophysiology study revealed a prolonged H-V interval. This was attributed to the radiation therapy he received to the chest. He was successfully treated with implantation of a permanent pacemaker. This case highlights this rare complication of radiation-induced conduction system disease and management of this potentially life-threatening condition.
