In order for your heart to beat properly, your heart’s tissue conducts electrical impulses throughout your heart muscle in a regular pattern. This electrical impulse causes the upper chambers (atria) ...

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 ...

LBBB is linked to electrical abnormalities, causing inefficient heart pumping, dilation, and systolic dysfunction. The study found LBBB associated with increased heart failure risk, surpassing other ...

Yogesh N. Reddy, MBBS: Hi. This is Yogesh Reddy, cardiology fellow at Mayo Clinic. Today we will be discussing the very common clinical scenario of a left bundle branch block (LBBB) on ...

A bundle branch block is characterized by a delay or an obstruction to the electrical impulses that prompt the heart to beat. These blockages along the heart’s electrical pathway can occur in healthy ...

THE electrocardiographic findings resulting from infarction of the interventricular septum were recently described by Roesler and Dressler.‡ These investigators found that when the septum was involved ...

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 ...

A left bundle branch block occurs when electrical conduction is unable to course through the left bundle and instead travels down the right bundle. The electrical impulse then reaches the left ...
