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.

Remember that T wave inversions and ST segment depression are normal in leads V1 to V3 in the presence of a right bundle branch block; thus, myocardial ischemia technically cannot be easily determined ...

A right bundle branch block (RBBB) involves a delay in the electrical impulses reaching the heart’s right ventricle, which can affect the heart’s ability to pump blood effectively. While RBBB doesn’t ...

Your heart isn’t plugged into an outlet. And you don’t use a switch to turn it on. But just like a lamp, your heart runs on an electrical system. Every time your heart beats, an electrical signal ...

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 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 ...

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) ...

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 ...
