Heart Conduction System (Cardiac Conduction) - Cleveland Clinic
WebJul 23, 2021 · Your heart (cardiac) conduction system sends the signal to start a heartbeat. It also sends signals that tell different parts of your heart to relax and contract (squeeze). This process of contracting and relaxing controls blood flow through your heart and to the rest of your body.

WebAug 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. These special cells are able to generate an action potential on their own (self-excitation) and pass it on to other nearby cells (conduction ...
Cardiac conduction system - Wikipedia
WebThe 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.

WebMay 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.
Conducting System of the Heart - Bundle of His
WebApr 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.

WebMar 17, 2022 · What is the cardiac conduction system? The human heart is an engine that has to work 24/7 to keep you alive, and it has to be reliable and effective. To do this, it relies on a specialized network of cells called the cardiac conduction system. It’s also known as your heart’s electrical system.

WebMar 24, 2022 · Your heartbeat is the contraction of your heart to pump blood to your lungs and the rest of your body. Your heart's electrical system determines how fast your heart beats. Your heartbeat. The contraction of the atria and ventricles makes a heartbeat. When your heart beats, it makes a “lub-DUB” sound.

WebDec 3, 2021 · The cardiac conduction system is designed for electrical impulse creation and propagation. It allows for initiation of impulses in the atrium, slowed conduction in the atrioventricular (AV) node, and rapid propagation through the His-Purkinje system to allow synchronous contraction in the ventricles.
Conduction System Tutorial - Medical School
WebThe conduction system of the heart. Normal excitation originates in the sinoatrial (SA) node, then propagates through both atria (internodal tracts shown as dashed lines). The atrial depolarization spreads to the atrioventricular (AV) node, passes through the bundle of His (not labeled), and then to the Purkinje fibers which make up the left ...
Conduction System | The Texas Heart Institute
WebConduction System | The Texas Heart Institute. Electrical impulses from your heart muscle (the myocardium) cause your heart to beat (contract). This electrical signal begins in the sinoatrial (SA) node, located at the top of the right atrium. The SA node is sometimes called the heart’s “natural pacemaker.”
