title: Recurrent life-threatening hyperkalemia without typical electrocardiographic changes.
abstract: 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.
