WebThe QRS complex (ventricular complex): normal and abnormal configurations and intervals. A complete QRS complex consists of a Q-, R- and S-wave. However, all three waves may not be visible and there is always variation between the leads. Some leads may display all waves, whereas others might only display one of the waves. WebIt is not always seen on the ECG of normal patients. When present, a normal U wave is of low amplitude (less than one fourth the height of the T wave) and has the same polarity as its T wave. When the U wave is abnormally prominent (more than half the height of the T wave), it should be included in the measurement of the QT interval.
