Pediatric Right Bundle Branch Block

Background

Right bundle branch block (RBBB) occurs when transmission of the electrical impulse is delayed or not conducted along the right bundle branch. Thus, the right ventricle depolarizes by means of cell-to-cell conduction that spreads from the interventricular septum and left ventricle to the right ventricle. This results in the characteristic electrocardiographic (ECG) pattern compared with a normal ECG as shown in the image below.

These electrocardiographs demonstrate a normal sin

These electrocardiographs demonstrate a normal sinus rhythm and a sinus rhythm with a right bundle branch block.
