Changes include non-specific repolarization changes, peaked T-waves, and QRS widening with ST-segment depression.\r\n\r\nNote also that while the management of hyperkalemia does not rely on the ECG alone, the presence of changes, which correlate with myocardial toxicity, warrant aggressive therapy. Calcium gluconate should be administered as soon as possible and ICU admission considered for these patients.\n"},{"insert":"Treatment of hyperkalemia"},{"insert":"\n","attributes":{"header":1}}]}
