$Figure 1. Aberrant conduction. The figure shows a supraventriclar extrasystole (an extra atrial impulse, discharged by an ectopic focus outside of the sinoatrial node). The supraventricular extrasystole arrives into the ventricles while the right bundle branch is still refractory, which is why it blocks the impulse. The resulting QRS-complex has a right bundle branch block pattern.$

This figure illustrates ECG patterns in LBBB and RBBB. As seen, LBBB is characterized by deep and broad S-waves in V1/V2 and broad and clumsy R-waves in V5/V6. RBBB is characterized by rSR’ complex in V1/V2, meaning that there are two R-waves and a large S-wave. Furthermore, the S-wave in V5/V6 is typically very broad in the presence of RBBB.
