WebThe DURATION of the T Wave is 0.10 to 0.25 seconds or greater. The AMPLITUDE of the T Wave is less than 5 mm. The SHAPE of the T Wave is sharply or bluntly rounded and slightly asymmetrical. A T Wave always follows a QRS Complex. The U Wave The U Wave probably represents the final state of repolarization of the ventricles. WebThe T wave represents ventricular repolarization. T waves are normally positive, but negative T waves are normal findings in leads aVR and V1 (and in young people, in V 2). The causes of pathologic T-wave inversion include myocardial ischemia and infarction, ventricular strain, and treatment with digoxin. Following a myocardial infarction, T ...
