What is a right bundle branch block?

What is a right bundle branch block?

Abnormal conduction: The signal to beat is distributed to through the heart by a specialized electrical system. The right bundle is one of the branches of this system. If conduction through the right bundle is slowed or blocked the parts of the heart it serves will contract late, seen as widening of the electrocardiographic qrs-wave. Unless the remainder of the conduction system fails, it usually isn't a problem. ...Read more

Bundle Branch Block (Definition)

There are 2 main branches of the heart's electrical system within the ventricles, the right bundle branch and the left bundle branch. Additionally, the left bundle branch has two sub-branches, the antero-superior fascicle and the posteroinferior fascicle. When one or more branches are disrupted, the resultant electrical abnormalities can be ...Read more

What occurs when someone has right bundle branch block?

Not much: Bundle branch block happens when there is a delay in conduction across a bundle. The his purkinjie fibers break into lb and rb. When there is a block in the rb, it is called rbbb. In most cases rbbb is of minimal consequence. ...Read more

What are side effects of right bundle branch block?

What are side effects of right bundle branch block?

None by itself: This is a fairly minor change in the electrical pattern of the heart which is harmless by itself but you need to know if it's related to any heart condition. Some people have it from birth with no consequences. If it comes later from a heart condition or even hypertension, it may mean that the wiring system is starting to get tired & it will be checked periodically to make sure it's stable. ...Read more

What are differences between left bundle branch block and right bundle branch block?

The location: Obviously the location of the electrical block in the conduction of electric impulses from the atrium to the ventricles is different. The electrical signals travel to the two ventricles through the left and the right bundle, the left then bifurcates to two fascicles itself. In my experience, the non-pathologic presence of right bundle branch block is more common. ...Read more
