U Wave Ecg. The PwaveECG interpretation usually starts with an assessment of the Pwave The Pwave is a small positive and smooth wave It is small because the atria make a relatively small muscle mass If the rhythm is sinus rhythm (ie under normal circumstances) the Pwave vector is directed downwards and to the left in the frontal plane and this yields a positive Pwave in lead.

ECG should be done on patients with hypokalemia Cardiac effects of hypokalemia are usually minimal until serum potassium concentrations are 3 mEq/L ( 3 mmol/L) Hypokalemia causes sagging of the ST segment depression of the T wave and elevation of the U wave With marked hypokalemia the T wave becomes progressively smaller and the U wave.
