Abstract:
We report a case of prolonged atrial fibrillation (AF) precipitated by new-onset generalized tonic-clonic convulsions and marijuana abuse in a developmentally normal 18-year-old adolescent with a structurally normal heart. Our case highlights an interesting association and a unique pathophysiology between generalized tonic-clonic convulsions, marijuana abuse, and AF. We suggest that seizures and marijuana abuse should be considered in the differential diagnosis of the etiology of AF in children.
