LONDON, England—New research has identified several high-risk variables associated with the need for a new permanent pacemaker after TAVI for aortic stenosis. None on the list are among the more ...

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 ...

Ambulatory rhythm monitoring may be a valuable surveillance tool for the underappreciated complication of delayed high-grade atrioventricular block (DH-AVB) following transcatheter aortic valve ...

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 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 ...

2:1 AV block is a form of second degree AV nodal block and occurs when every other P wave is not conducted through the AV node to get to the ventricles and thus every other P wave is NOT followed by a ...

A trifascicular block is the combination of a right bundle branch block, left anterior or posterior fascicular block and a first degree AV block (prolonged PR interval). The term “trifascicular block” ...
