Heart Conduction Animation

An excitation signal an action potential is created by the sinoatrial sa node. In this medical 3d animation we take a look at the heart and how it pushes oxygenated blood out to the body then returns to be re oxygenated by the lungs and pushed out again. Dysfunction of the conduction system can cause irregular fast or slow heart rhythms.

Heart conduction animation. Fig 1 animation of the spread of conduction through the heart the sequence of electrical events during one full contraction of the heart muscle. Thanks to mcgraw hill you can watch this video about the conducting system of the heart. Your heart has a special electrical system called the cardiac conduction system. Conduction system of the heart sinoatrial node av node bundle of his purkinje fibers animation duration.

Electrical signals cause muscles to contract. This results in the continuous exchange of oxygen rich blood with oxygen poor blood that is necessary to keep you alive. The conduction system consists of specialised heart muscle cells and is situated within the myocardium. As the signal travels it causes the heart to contract and pump blood.

The conduction system keeps your heart beating in a coordinated and normal rhythm which in turn keeps blood circulating. This system controls the rate and rhythm of the heartbeat. With each heartbeat an electrical signal travels from the top of the heart to the bottom. There is a skeleton of fibrous tissue that surrounds the conduction system which can be seen on an ecg.

The wave of excitation spreads across the atria causing them to contract. Drg bhanu prakash animated medical videos 23167 views. Skip navigation sign in.
