Hyperkalemia is generally associated with electrocardiographic (ECG) changes and these changes have been used to follow the effects of high serum potassium (K+) levels on the heart. It is known that chronic renal impairment may diminish the toxic effects of hyperkalemia on ECG abnormality formation. (1-3) Here, we report a case of recurrent severe hyperkalemia without any significant ECG changes in a patient with normal baseline renal function.
高钾血症通常与心电图（ECG）改变相关，这些改变已被用于追踪高血清钾（K+）水平对心脏的影响。已知慢性肾功能损害可能会减轻高钾血症对心电图异常形成的毒性作用。（1 - 3）在此，我们报告一例基线肾功能正常的患者反复出现严重高钾血症但无任何明显心电图改变的病例。
