     • The current leaves the AV node down a bundle of cells termed the "bundle of His" located inferior to the AV node in the interventricular septum. The bundle of His then transmits the conduction down two bundle branches that arc throughout the two ventricles, named the right and left bundle branches.

   Can a bundle branch block cause a heart block?

   • Your heart’s two ventricles usually contract at the same time. But a bundle branch block delays the electrical signal, therefore, the ventricle that receives the delayed signal will contract at a later time. Healthcare providers don’t always treat bundle branch blocks. But they may treat the underlying health problems that cause the block.

   What is a right bundle branch block?

   • Similarly, when a person has a “left” bundle branch block, the left side of the heart beats a bit behind the right side. A right bundle branch block is less serious than a left bundle branch block, which can be a sign of an underlying heart condition, such as coronary artery disease.

   What is the left bundle branch of the atrioventricular bundle?

   • The left bundle branch or crus sinistrum (Latin) branches from the atrioventricular bundle at the start of the muscular interventricular septum. It is made up of numerous small fascicles that become flattened sheets. These fascicles occupy the left half of the muscular interventricular septum.

   How does a bundle branch affect your body?

   • Bundle branches form part of your heart conduction system, which controls your heartbeat. A block affects your body based on where it’s located: Right bundle branch block: If you have RBBB, the blockage is in the bundle branch that carries the electrical impulse to your right ventricle.

    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.
