Right Bundle Branch Block
Also written as RBBB.
Thus, with right bundle branch block,\ntude of electrical forces directed to the left and poste- the terminal QRS vector is oriented to the right and\nriorly.
What our notes say
- Thus, with right bundle branch block,\ntude of electrical forces directed to the left and poste- the terminal QRS vector is oriented to the right and\nriorly. (Harrisons Cardiovascular Medicine 2nd Edition 2)
- If right bundle branch block is present, there may be an ‘M’ in V1 and/or a ‘W’ in V6. (ECG MADE EASY (1))
- Investigations\n1- Chest X-ray:\n-Cardiomegaly with RVH & RAD.\n' - Plethoric lungs.\n2- ECG:\n- RVH & RAD.\n- Right bundle branch block is common.\n3- Echo: diagnostic\n4- Cardiac catheter: pre operative. (BABY NELSON PEADS)
- ECG: sinus tachycardia (commonest), S1Q3T3, right bundle branch block, T-wave inversion V1–V4 (right heart strain). (DVT and Venous Thromboembolism (with Pulmonary Embolism))
- ST-segment and T-wave changes, or right bundle branch block.\nABGs: Typically show a reduced PaO2 and a normal or low PaCO2, (Davidson's Essentials of Medicine - 2nd)
- \n\nwill widen with right bundle branch block because the left atrial–left ventricular diastolic pressure gradient. (Harrisons Cardiovascular Medicine 2nd Edition 2)
