The QRS complex is the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG or EKG). It is usually the central and most visually obvious part of the tracing. It corresponds to the depolarization of the right and left ventricles of the heart and contraction of the large ventricular muscles. WebIf the QRS duration is ≥0,110 seconds but <0,12 seconds, the right bundle branch block is said to be incomplete. Note that a second r-wave (r') may occur as a normal variant in lead V1 (the normal variant has normal QRS duration). Moreover, the normal septal q-waves (seen in V5, V6) are not affected by right bundle branch block.
