Electrical conduction system of the heart. The pacemaking signal generated in the sinoatrial node travels through the right atrium to the atrioventricular node, along the Bundle of His and through bundle branches to cause contraction of the heart muscle. This signal stimulates contraction first of the right and left atrium,The heart's electrical system. In the simplest terms, the heart is a pump made up of muscle tissue. Like all muscle, the heart needs a source of energy and oxygen to function. The heart's pumping action is regulated by an electrical conduction system that coordinates the contraction of the various chambers of the heart. diagram of electrical conduction system of the heart

Cardiac Conduction System. The SA node is the natural pacemaker of the heart. You may have heard of permanent pacemakers (PPMs) and temporary pacing wires (TPWs) which are used when the SA node has ceased to function properly. The SA node releases electrical stimuli at a regular rate, the rate is dictated by the needs of the body. Overview. The cardiac conduction system is a group of specialized cardiac muscle cells in the walls of the heart that send signals to the heart muscle causing it to contract. The main components of the cardiac conduction system are the SA node, AV node, bundle ofdiagram of electrical conduction system of the heart The heart is an amazing muscle. For reasons described on this previous blog, The Anatomy And Heart Function, I am constantly marveling at all the complex elements that makes the heart operate. Interestingly enough Electricity has a lot to do with the actual starts and stops (aka contractions) in the cardiac conduction system.

May 20, 2015  Electrical Conduction System of the Heart (cardiac conduction system): This video explains how the SA node, AV node, bundle of His, right and diagram of electrical conduction system of the heart 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. Text in this Example: The hearts electrical system controls all the events that occur when your heart pumps blood. Each beat of your heart begins with an electrical signal from the sinoatrial node, called SA node. The signal is generated as the two vena cavae fill your hearts right atrium with blood from other parts of your body. Cardiac Conduction System Disorders. A more serious condition, known as heart block, involves the impairment or blockage of electrical signal transmissions between the heart's atria and ventricles. Heart block electrical disorders range from first to third degree and are accompanied by symptoms ranging from lightheadedness and dizziness to palpitations and irregular heartbeats.
