Antimalarial drugs are well known for their cardiovascular toxicity. Quinine, the most famous antimalarial agent, mostly causes bradycardia. Quinidine, its dextrorotatory isomer, may cause 1:1 atrioventricular (AV) conduction during atrial flutter. The newly developed drug mefloquine was reported to have fewer cardiac side effects. We describe a 63-year-old male patient with atrial flutter in whom mefloquine use was associated with 1:1 AV conduction, and who then responded to therapy with digoxin and sotalol. The patient had a history of palpitations. This case report emphasizes that mefloquine should be used with caution in patients with a history of palpitations or underlying heart disease.
