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 ...

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) ...

There are only a few sinus rhythm QRS complexes available to examine on this ECG. Using lead V1 an incomplete right bundle branch block is seen. A prolonged QT interval is present that extends all the ...

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 ...

The ECG shows regular P waves at 60 beats per minute (bpm) with no conduction to the ventricles. The ventricular rate is about 70 bpm with QRS duration of 0.20 and a left bundle branch block (LBBB) ...

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 ...

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 ...
