Severe hyperkalemia may be concealed in the electrocardiogram (ECG). We present the case of a critically ill patient with severe bradycardia and the BRASH syndrome. In critically ill patients, double counting of the heart rate is frequently a marker of severe hyperkalemia (Littmann sign). In our case, hyperkalemic double counting only appeared in the ECG performed during percutaneous pacing. The Littmann sign helped with the early recognition of hyperkalemia and the BRASH syndrome.
严重高钾血症可能隐藏在心电图（ECG）中。我们报告了一例重症患者伴严重心动过缓及 BRASH 综合征的病例。在危重症患者中，心率双重计数常常是严重高钾血症的标志（利特曼征）。在我们的病例中，仅在进行经皮起搏时进行的心电图中出现高钾血症的双重计数。利特曼征有助于早期识别高钾血症和 BRASH 综合征。
