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 ...

The mechanism of the benefits achieved with the therapy has been attributed to resynchronization of the dyssynchronous segments resulting from bundle branch block, especially left bundle branch block ...

Among patients with a wide QRS, cardiac resynchronization therapy (CRT) seems to help patients with an intraventricular conduction delay (IVCD) as much as it does those with left bundle branch block ...

Newer pacing method matched standard cardiac resynchronization therapy with respect to clinical outcomes in the first ...

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 ...

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.

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 ...
