The left ventricle contracts a little later than it normally would. Right bundle branch through the heart muscle and slowly activate the left ventricle.

That's because the signal has to spread from the Travel down this path the way it normally would. With the left branch of the electrical conduction system. In left bundle branch block, there is a problem As the signal travelsĪlong the heart's conduction system, it triggers nearby parts of the heart to contractĮlectrical signal to the bottom of the heart and cause the ventricles to beat. To the lower chambers (right and left ventricles) of the heart. From there, the signal activates the left atrium and travels Healthy heart, the signal to start your heartbeat begins in the upper right chamber of Upper chambers are called atria, and the 2 lower chambers are called ventricles.

Problem with the heart’s electrical wiring (conduction) system.
