Almost one-third of patients undergoing transcatheter aortic valve replacement (TAVR) with a balloon-expandable device develop new-onset left bundle branch block, although the condition resolves by ...

A left anterior fascicular block (LAFB) also known as a left anterior hemiblock (LAHB) occurs when the anterior fascicle of the left bundle branch is no longer able to conduct action potentials. The ...

Impulses, or electrical signals, travel through both the left and right chambers of your heart to make it pump. But if the pathway is blocked, the impulses may move slower than normal or irregularly.

Left bundle branch block (LBBB) is a type heart block. It results from a problem with the electrical conduction system that enables the heart to beat. It may cause no symptoms, but an ...
