The electrical stimulus travels down through the conduction pathways and causes the heart's ventricles to contract and pump out blood. The 2 upper chambers of the heart (atria) are stimulated first and contract for a short period of time before the 2 lower chambers of the heart (ventricles).
12 Μαρ 2023 · The electrical system of the heart is critical to how it functions. It controls the electrical impulses that cause your heart to beat and their conduction, which organizes the beating of your heart. The movement of electrical signals across the heart is what is traced on an electrocardiogram (EKG). The EKG is also what allows irregularities in ...

The heart's electrical system. The heart is a pump made up of muscle tissue. Like all muscles, the heart needs a source of energy and oxygen to work. The heart's pumping action is controlled by an electrical system. This system organizes how the chambers of the heart contract and pump blood.
The cardiac conduction system (CCS, also called the electrical conduction system of the heart) [1] transmits the signals generated by the sinoatrial node – the heart's pacemaker, to cause the heart muscle to contract, and pump blood through the body's circulatory system.
The heart's electrical system. In the simplest of terms, the heart is a pump made up of muscle tissue. The heart's pumping action is controlled by an electrical conduction system that coordinates the contraction of the heart chambers. Click Image to Enlarge. How does the heart beat?
23 Ιουλ 2021 · Your heart’s conduction system is the network of signals that keeps your heart beating. These electrical signals make your heart contract or relax. Each contraction also controls blood flow through your heart.
