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. Web11 de mar. de 2013 · This duration (0.12 to 0.20 sec) is called the PR interval; on the electrocardiogram (ECG), it’s measured from the start of the P wave to the start of the QRS complex. Normally, the QRS complex is 0.06 to 0.11 sec (60 to 110 msec) wide. A QRS complex wider than 0.11 sec indicates either a bundle branch block or a QRS complex of …
