WebNov 8, 2024 · Lesson #9: T Wave. The T wave indicates the repolarization of the ventricles. It is a slightly asymmetrical waveform that follows (after a pause), the QRS complex. Take note of T waves that have a downward (negative) deflection or of T waves with tall, pointed peaks. The U-wave is a small upright, rounded bump. When observed, it follows the T-wave. WebFeb 15, 2024 · Interpretation. Narrow, symmetrical 'tented' T waves - suggestive of hyperkalaemia. Tall T waves with concave ST elevation in the precordial leads - suggestive of benign early repolarisation. Prominent, symmetrical and pointed ('hyperacute') T waves - suggestive of myocardial infarction.

WebThe U wave is a small, rounded deflection sometimes seen after the T wave (see Fig. 2-2 ). As noted previously, its exact significance is not known. Functionally, U waves represent the last phase of ventricular repolarization. Prominent U waves are characteristic of hypokalemia (see Chapter 10 ). Very prominent U waves may also be seen in other ... WebJul 15, 2015 · Both peaked T waves and rapid-upslope ST segment depression are common normal findings during an exercise test.
