We report a 46‐year‐old man who presented with hypothyroidism. An electrocardiogram obtained at the time of the first examination revealed Brugada electrocardiographic (Brugada‐ECG) waveforms in leads V1 to V3. The patient and his family had no history of arrhythmia and syncopal attack. The Brugada‐ECG waveforms disappeared with the normalization of thyroid function. The case suggested that hypothyroidism could lead to secondary Brugada‐ECG waveforms because of its effect on myocardial ion channels. (PACE 2012; 35:e222–e225)
