Pseudo myocardial infarct--electrocardiographic pattern in a patient with diabetic ketoacidosis.

Diabetic ketoacidosis is an extremely serious complication of diabetes mellitus. It arises because of a complex disturbance in glucose metabolism. There is usually a precipitating cause such as sepsis or myocardial infarction. If not recognised and appropriately treated, it can have devastating consequences. This is a case report of a patient with severe diabetic ketoacidosis and interesting electrocardiographic findings. The initial electrocardiographic (ECG) findings were suggestive of an acute myocardial infarction. The ECG changes normalised remarkably following initial management of the diabetic ketoacidosis. There have been only occasional reports of hyperkalemia causing electrocardiographic changes, closely resembling those of acute myocardial infarction.
