Atrial Fibrillation Induced by Carbon Monoxide Poisoning and Successful Treatment with Hyperbaric Oxygen

Carbon monoxide (CO) intoxication is one of the major public health hazards which may go unnoticed as this is a colorless, odorless and tasteless gas. The manifestations of the CO poisoning are far-reaching. Although CO affects almost every organ in the body, cerebral and myocardial involvement are predominant due to the hypoxia-induced cellular damage. The mainstay treatment is providing high-flow oxygen and in some instances hyperbaric oxygen therapy. In the literature, there have been few cases of CO poisoning-induced atrial fibrillation (AF) reported. We hereby report an AF caused by CO toxicity in a young male patient and successful conversion to sinus rhythm with the hyperbaric therapy.
