Severe metabolic abnormalities can sometimes create confusing and grossly abnormal electrocardiogram (ECG) recordings. In this case study, a man who had diabetic ketoacidosis and acute renal failure with severe hyperkalemia had an unusual cardiac rhythm strip recording. A subsequent 12-lead ECG showed findings compatible with an acute myocardial infarction of the anterior wall. An ECG obtained after aggressive treatment of the metabolic disorders had a more normal pattern.
