Eck u waves
WebEKG changes can include increased amplitude and width of P wave, T wave flattening and inversion, prominent U waves and apparent long QT intervals due to merging of the T and U wave. The 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 ... WebDec 6, 2015 · U wave on ECG occurs after the T wave and is usually seen in the mid precordial leads. In hypokalemia, T wave becomes flattened and U wave becomes prominent (or apparently so because of near absence …
