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 ...

Better devices and changes in implant depth have likely led to fewer LBBBs over time, but the issue needs continued attention ...

First-degree heart block is the mildest type and often requires no treatment. Third-degree heart block is the most severe and ...

A person with RBBB typically does not have symptoms and may not know they have the condition. On rare occasions, a person may faint due to a severe block, though this is unlikely to occur unless other ...

Dear Dr. Roach: I’m a female, age 70, who is 5 feet, 4 inches tall and weighs 125 pounds. I have no problems with cholesterol, diabetes or blood pressure. I do not take any medications, just vitamins.

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 ...

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 ...
