WebRight Bundle Branch Block (RBBB) ECG Review Learn the Heart - Healio WebJun 20, 2024 · Bundle Branch Blocks. Definition: Interruption of the normal conduction system leading to aberrant conduction and an abnormal QRS morphology. Anatomy: At the AV node, conduction splits into the right and left bundle branches. The left bundle branch is composed of anterior and posterior branches.
