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.
