WebRight bundle branch block (RBBB) The diagnostic criteria for RBBB are: 2. QRS > 120 ms (3 small squares) RSR’ pattern in V1-V3. Wide, slurred S wave in lateral leads – I, aVL, V5-V6. A quicker simpler way to recognise and interpret this … WebIn a right bundle branch block (RBBB), depolarization begins the way that it always does, in the sense that the impulse travels through the AV node and down the left bundle branch to the interventricular septum. 2 The septum is then activated by the LBB's posterior fascicle, and depolarization occurs in a left-to-right fashion. dave\u0027s poem
