In bundle branch block, the pathway these impulses follow is delayed or blocked. The pathway includes two branches the left and the right bundles. If one bundle is damaged, the ventricles rely on the other bundle to receive and respond to signals from the right atrium.
Right bundle branch block is a problem with your right bundle branch that keeps your heart’s electrical signal from moving at the same time as the left bundle branch. Instead of moving together on the left and right sides, the signal on the right side is running behind.
Diagnosis. If you have a right bundle branch block and you're otherwise healthy, you might not need a full medical checkup. If you have a left bundle branch block, you will need a thorough medical exam. Tests that can be used to diagnose a bundle branch block or its causes include: Electrocardiogram (ECG or EKG).
Right bundle branch block (RBBB) is a cardiac conduction abnormality that can occur due to various underlying conditions affecting the heart’s electrical system.
A bundle branch block (BBB) is a blockage or disruption to the electrical signal that causes your heart to beat. BBB can affect your right ventricle (right bundle branch block), left ventricle (left bundle branch block) or both ventricles.
A bundle branch block refers to a condition that arises from a blocked electrical pathway in the heart, causing the left and right sides of your heart to beat out of sync. When a person has a “right” bundle branch block, the right side of the heart beats slightly later than the left side.
A right bundle branch block (RBBB) is a heart block in the right bundle branch of the electrical conduction system. [1] During a right bundle branch block, the right ventricle is not directly activated by impulses traveling through the right bundle branch. However, the left bundle branch still normally activates the left ventricle.
