Moreover, the specific criteria used to classify LBBB are not indicated in clinical practice guidelines [7,8]. In left bundle branch block, there is a problem with the left branch of the electrical conduction system. The electrical signal can't travel down this path the way it normally would. The signal still gets to the left ventricle, but it is slowed down, compared to the right branch. Because of this, the left ventricle contracts a little later than it normally would.
