A patient with a family history of sudden cardiac death and a structurally normal heart presented with a resting ECG intermittently displaying a saddle-type Brugada-ECG, which could be reproducibly converted to a coved-type ECG pattern suggestive of Brugada syndrome. However, no ST-segment changes occurred in the presence of a true right bundle branch block (RBBB) in the same patient. In consideration of the inalienable diagnostic criterion of dynamic ECG abnormalities in the right precordial leads in Brugada syndrome, setting the diagnosis in patients with true RBBB may be unattainable.
一名有心脏性猝死家族史且心脏结构正常的患者，静息心电图间歇性显示马鞍型Brugada心电图，可重复性地转变为提示Brugada综合征的穹窿型心电图模式。然而，该患者在出现真正的右束支传导阻滞（RBBB）时未发生ST段改变。鉴于Brugada综合征右胸前导联动态心电图异常这一不可分割的诊断标准，对真正RBBB患者进行诊断可能无法实现。
