Abstract:
Ciguatera fish poisoning occurs with ingestion of fish containing ciguatoxin. It causes a clinical syndrome that comprises classic gastrointestinal, neurological and cardiovascular symptoms. Ciguatoxin is a sodium channel agonist with cholinergic and adrenergic activity. Although cardiovascular symptoms are rare with ciguatoxin, we report two cases with bradycardia and hypotension. Fatality and long-term sequelae are not uncommon with ciguatoxin poisoning and educating the general population is essential.
