Your heart’s conduction system is the network of nodes (groups of cells that can be either nerve or muscle tissue), specialized cells and electrical signals that keep your heart beating.

Nov 6, 2025 · The pumping action of the heart muscle is controlled by an spontaneous electrical impulse, conducted around the heart by specialised cells. This article will look at the key structures …

May 10, 2020 · Both conducting and specialised muscle cells form the hearts conduction system and orchestrate cardiac contraction. The electrical system is intrinsic to the heart meaning that …

The conduction system consists of specialized heart muscle cells, situated within the myocardium. [3] There is a skeleton of fibrous tissue that surrounds the conduction system which can be seen on an …

Aug 17, 2023 · This article will discuss the anatomy of the cardiac conduction system and its different parts. Disorders of the conduction pathway and how they manifest clinically will also be discussed.

The heart generates its own electrical impulse as part of the cardiac conduction system. The components of the cardiac conduction system include the sinoatrial node, the atrioventricular node, …

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

The heart's pumping action is regulated by an electrical conduction system that coordinates the contraction of the various chambers of the heart. How does the heart beat? An electrical stimulus is …

The conduction system of the heart. Normal excitation originates in the sinoatrial (SA) node, then propagates through both atria (internodal tracts shown as dashed lines).

May 5, 2025 · This group of muscle cells is called the cardiac conduction system. The main parts of the system are the SA node, AV node, bundle of HIS, bundle branches, and Purkinje fibers.
