Abstract
Electrocardiograms were recorded in 24 patients with serum potassium of 2.5 mEq./L. or less. Only 5 (20.8%) had severe-classic changes of hypokalemia. Sixteen (66.7%) had mildmoderate changes and 3 (12.5%) had no changes. It is concluded that, although most (21 of 24, or 87.5%) of these patients had at least some definite electrocardiographic changes, in individual patients there is poor correlation between the severity of the hypokalemia and the electrocardiographic abnormalities. When changes were present, however, they were clinically helpful and evolved as expected during potassium replacement.
