Like all muscle, the heart needs a source of energy and oxygen to function. The heart's pumping action is regulated by an electrical conduction system that coordinates the contraction of the various …

Your cardiac conduction system is the network of nodes, cells and signals that controls your heartbeat. Each time your heart beats, electrical signals travel through your heart.

Mar 12, 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 …

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 …

Detailed anatomical description of the heart's electrical system, including simple definitions and a labeled, full-color illustration.

Learn the principles of cardiac physiology, electrocardiography and ECG interpretation. The action potential and conduction system are also discussed.

Aug 23, 2025 · The heart’s rhythmic beating is governed by a precise electrical conduction system, depicted step-by-step in this informative diagram.

Normally, the heartbeat starts in the right atrium in a group of special heart cells called the sinoatrial (or sinus) node. These cells act as a pacemaker for the heart. The heart's pacemaker sends out an …

The electrical signal spreads through the chambers of the heart. First, the atria are activated. The electrical signal then travels down through the conduction pathways to the heart's ventricles. This …

Sep 10, 2024 · The conduction system, also called the cardiac electrical system, helps the heart contract, thus pumping blood through the body.
