Brugada syndrome (BrS) is a disorder leading to potentially life-threatening ventricular arrhythmias in patients with an apparently normal heart. It mostly affects men of Asian descent, and the prevalence varies between ethnicities. Typical ECG abnormalities with no symptoms are referred to as the Brugada pattern, and hypothyroidism is a potential trigger of this. We report on a Caucasian man with severe hypothyroidism and Brugada ECG pattern, which normalised after starting replacement therapy. The association has been previously described in only a few patients.
