   What happens if a heart bundle is blocked?

   • If both the right and the left bundles are blocked, the main complication is a complete blockage of the electric signaling from the upper to the lower chambers of the heart. The lack of signaling can slow the heart rate. A slowed heart rate may lead to fainting, irregular heart rhythms and other serious complications.

   What are the two branches of the bundle of his?

   • There are two branches of the bundle of His: the left bundle branch and the right bundle branch, both of which are located along the interventricular septum. The left bundle branch further divides into the left anterior fascicle and the left posterior fascicle. These structures lead to a network of thin filaments known as Purkinje fibers.

   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.

   Jun 11, 2022 · Bundle branch block is a condition in which there's a delay or blockage along the pathway that electrical impulses travel to make the heart beat. It sometimes makes it harder for the heart to pump blood to the rest of the body.

   May 5, 2022 · 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.

   The bundle branches, or Tawara branches, are offshoots of the bundle of His in the heart's ventricle. They play an integral role in the electrical conduction system of the heart by transmitting cardiac action potentials from the bundle of His to the Purkinje fibers.
