There is increasing literature suggesting that in the context of chest pain, a new RBBB is highly concerning forOMIand a potential indication for immediate reperfusion therapy. The right bundle branch is supplied by LAD perforators in most patient populations and thus occlusion of this branch may ...

In patients with radiologically confirmed PE, there is evidence to suggest that ECG changes of right heart strain and RBBB are predictive of more severe pulmonary hypertension; while the resolution of anterior T-wave inversion has been identified as a possible marker of pulmonary reperfusion following...
Clinically, bifascicular block presents with one of two ECG patterns: Right bundle branch block (RBBB) with left anterior fascicular block (LAFB), manifested as left axis deviation (LAD) RBBB and left posterior fascicular block (LPFB), manifested as right axis deviation (RAD) in the absence...
If the paced QRS morphology changes from a LBBB pattern (indicating RV placement) to a RBBB pattern (indicating LV placement), this suggests that the electrode has eroded through the interventricular septum A chest x-ray will usually help to confirm the diagnosis ...
ECG ExamplesExample 1Atrial fibrillation:Irregular ventricular response Coarse fibrillatory waves are visible in V1 “Sagging” ST segment depression is visible in V6, II, III and aVF, suggestive of digoxin effectExample 2Atrial fibrillation:
