Aug 17, 2023 · The cardiac conduction system is a network of specialized cardiac muscle cells that initiate and transmit the electrical impulses responsible for the coordinated contractions of each cardiac cycle.
Apr 24, 2023 · 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 involved in the generation and conduction of that electrical impulse.
Jul 23, 2021 · The heart 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. These signals cause different parts of your heart to expand and contract.
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.
May 10, 2020 · This article will discuss the components of the heart’s conduction system including their anatomy and clinical significance. The heart has two main types of cells: 1 Conducting cells: generate and propagate electrical impulses.
Mar 17, 2022 · It’s also known as your heart’s electrical system. Cells in the cardiac conduction system can generate electrical impulses and then distribute the signal throughout your heart. While all cells in your heart can conduct electricity, the cells in this system conduct it at very specific speeds.
Jun 28, 2016 · The conducting system of the heart consists of cardiac muscle cells and conducting fibers (not nervous tissue) that are specialized for initiating impulses and conducting them rapidly...
Description. The cardiac conduction system initiates and coordinates the contraction of the myocardial tissue of the heart. This system, which receives autonomic input from the cardiac plexus, consists of highly specialized cardiac muscle cells.
Jul 24, 2019 · In this video, Dr Mike explores the cardiac conduction system. beginning at the SA node and propagating through atria myocardia, then AV node and propagating through the AV bundle (bundle of...
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).
