  2. The cardiac conduction system (CCS, also called the electrical conduction system of the heart) 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.

  3. In a healthy heart all activities and rests during each individual cardiac cycle, or heartbeat, are initiated and orchestrated by signals of the heart's electrical conduction system, which is the "wiring" of the heart that carries electrical impulses throughout the body of cardiomyocytes, the specialized muscle cells of the heart.

  4. Apr 24, 2023 · The cardiac conduction system is a collection of nodes and specialised conduction cells that initiate and co-ordinate contraction of the heart muscle. It consists of: Sinoatrial node. Atrioventricular node. Atrioventricular bundle (bundle of His) Purkinje fibres.

  5. May 10, 2020 · The cardiac conduction system involves the spread of electrical activity from the sinoatrial node, to the atrioventricular node, down the bundle of His and along the Purkinje fibres. As the electrical activity spreads along the heart’s conduction system it initiates myocardial contraction in the surrounding myocardial tissue.

  6. 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 generated by the sinus node (also called the sinoatrial node, or SA node).

  7. Aug 25, 2022 · The electrical conduction system of the heart, (also called the cardiac conduction system) [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.
