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.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
