Nicotine gum-induced atrial fibrillation.
A 39-year-old man with no prior history of atrial fibrillation was hospitalized with atrial fibrillation and a rapid ventricular rate. For the 7 months before presentation, he had been chewing nicotine polacrilex gum on his own. The week he first developed palpitations, he was chewing more than 1 piece of nicotine Polacrilex gum per hour during work. His diagnostic work-up during hospitalization found no cause for atrial fibrillation. He was cardioverted to sinus rhythm. At 6-month follow-up, he had not renewed chewing nicotine polacrilex gum, was in sinus rhythm, and had no history of palpitations. The temporal relation between more frequent gum usage and the excessive consumption of nicotine polacrilex chewing gum with a probable high serum nicotine level at the time the patient developed his first episode of atrial fibrillation suggests a causal relationship.
