WebThe appearance of U-waves in hypokalaemia. In severe hypokalaemia giant U-waves have been described that can be mistaken for peaked T-waves. 12 To differentiate between peaked T-waves and giant U-waves the following rules can be used to aid the diagnosis. WebThe U-wave is a deflection following the T wave. Hypokalemia causes enlarged and prominent T waves on the EKG. Potassium levels that are critically low (<1.7) can lead to …
