A bundle branch block is a defect of the bundle branches or fascicles in the electrical conduction system of the heart.
A bundle branch block causes a delay in the depolarization of the right (RBBB) or left (LBBB) ventricle. In RBBB the QRS complex shows a second peak or R' in V1. Check V1 when QRS > 0.12 sec. When the terminal force of the QRS in V1 is below the baseline (i.e. QS wave), a LBBB is the most likely diagnosis.
