Conduction block is an abnormal rhythm of your heart beat, it is also known as heart block. With every beat of your heart, electric signal travel from the upper chamber (Atria) and lower chamber (ventricles) of your heart. This electric signal instructs your heart to pump blood. In the conduction block situation, the signal frequency slows down and that affects the heartbeat rate, rhythm, and pattern. In some, it is a congenital issue.
A normal heartbeat comes from an electrical signal that comes from the natural pacemaker of the heart. A sinoatrial node is the heart’s natural pacemaker which is located at the top of the right atrium. The electrical signal travels from the upper chamber to the lower chamber of the heart and the signal passes through the bundle. This bundle is further divided into thin wired structures, these are known as branches and extend to the right and left ventricles. The electric signal travels from bundle branches and reaches to muscle cell of the ventricles, it allows them to contract and pump blood. When these signals are interrupted or delayed the conduction block happens.
The people who have heart block doesn’t always show the sign and symptoms of it. On the other hand, others may reflect the following symptoms:
