Abstract

Carbon monoxide (CO) can cause a variety of electrocardiogram (ECG) changes. The Brugada ECG patterns are very rare in CO poisoning cases. We detected a patient with a CO-induced type 1 Brugada ECG pattern with chest pain. The panel genetic test and echocardiogram revealed normal findings. The Brugada phenocopy gradually improved over 3 days. We reviewed the literature and suggested possible mechanisms.
