Figure 1: ECG Strip[1]
A right bundle branch block occurs when "activation of the right ventricle is delayed as depolarization has to spread across the septum from the left ventricle."[2] This delayed right ventricular activation gives rise to a slurred S wave and secondary depolarization abnormalities, such as ST depression and T wave inversion.[2]
