Given today's short hospital stays after transcatheter aortic valve replacement (TAVR), there may be a role for selective long-term monitoring to flag delayed conduction abnormalities, studies showed.

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 ...

A specialist tells how to interpret subtle changes on the ECG, including those caused by two life-threatening syndromes you might otherwise miss. Reading ECGs is like learning to appreciate art—it is ...
