Describe the Passage of a Normal Impulse Through the Conduction

Question

Examlex · Accepted Answer

The Answer is The passage of a normal impulse through the conduction system of the heart begins in the sinoatrial (SA) node, located in the right atrium. The SA node generates an electrical signal that spreads through the atria, causing them to contract and push blood into the ventricles.

The electrical signal then travels to the atrioventricular (AV) node, where it is briefly delayed to allow the ventricles to fill with blood. From the AV node, the impulse travels down the bundle of His, which divides into the left and right bundle branches, and then into the Purkinje fibers.

These fibers distribute the electrical signal throughout the ventricles, causing them to contract and pump blood out to the rest of the body. This coordinated sequence of electrical impulses ensures that the heart beats in a regular and efficient manner, allowing for proper circulation of blood throughout the body. Any disruption in this conduction system can lead to abnormal heart rhythms or arrhythmias.
