Abstract

Two cases of implantable cardioverter-defibrillator lead impedance changes that corresponded with changes in serum potassium are described. In the first case, an audible lead alert was triggered due to a significant change in lead impedance caused by hyperkalemia. In the second case, a patient was admitted with hyperkalemia and renal failure. Device interrogation revealed a change in lead impedance corresponding to changes in serum potassium. As devices and leads become more sophisticated, their role for monitoring parameters and triggering alerts may expand to include electrolyte and other metabolic changes.
