As potassium levels decline U waves appear following the T wave. At the same time T waves will diminish. When severe, the T wave may disappear and a prominent U wave can be mistaken for the T wave, thus one of the reasons that hypokalemia is always included in a differential for prolonged QT interval.<\/p>\n<p>This young man was extremely hypokalemic, with a K<sup>+<\/sup> of 1.7mEq.
