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.
我们报告一名46岁患有甲状腺功能减退症的男性。首次检查时获得的心电图显示V1至V3导联出现Brugada心电图（Brugada-ECG）波形。患者及其家族无心律失常和晕厥发作史。随着甲状腺功能恢复正常，Brugada-ECG波形消失。该病例提示，甲状腺功能减退症因其对心肌离子通道的影响可导致继发性Brugada-ECG波形。
