Right bundle branch block
Right Bundle Branch Block
Right Bundle Branch Block (RBBB) is a condition in which there's a delay or obstruction along the pathway that electrical impulses travel to make the right ventricle contract. It is a type of heart block.
Pronunciation
Right Bundle Branch Block: /ˈraɪt ˈbʌndl ˈbræntʃ blɒk/
Etymology
The term is derived from the anatomical location and the nature of the condition. The bundle branch is part of the electrical system of the heart, and a block indicates an obstruction or delay in the pathway.
Definition
Right Bundle Branch Block (RBBB) is a blockage of electrical impulses on the right bundle branch of the heart. This can lead to an abnormal sideways (rightward) shift of the heart's electrical axis. The condition can be diagnosed through an Electrocardiogram (ECG).
Symptoms
RBBB itself usually does not cause any symptoms. However, it can be associated with other underlying heart conditions that may produce symptoms such as chest pain, shortness of breath, or fainting.
Causes
RBBB can be caused by a variety of conditions that damage the heart's electrical system, including heart disease, high blood pressure, heart attack, and cardiomyopathy.
Treatment
Treatment for RBBB usually involves addressing the underlying condition that caused the block. In some cases, no treatment is necessary. If the block is causing significant symptoms or is associated with a high risk of complete heart block, a pacemaker may be implanted.
