Results:
Left Bundle Branch Block (LBBB) DDx
Key Point Overview: Left bundle branch block (LBBB) is an intraventricular conduction delay that results from a block in the left bundle branch of the heart’s electrical conduction system. It…
Left Bundle Branch Block
Key Points Definition: LBBB occurs when electrical conduction through the left bundle branch is delayed or blocked, resulting in asynchronous and delayed activation of the left ventricle (LV) and a…
