The electrical conduction system of the heart transmits signals generated usually by the sinoatrial node to cause contraction of the heart muscle. 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 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
Electrical Conduction System of the Heart aka the Conduction Pathway for nurses and nursing students.Subscribe to NurseMinder https://www.youtube.com/c/nurse.. Conduction Disorders. Also known as Heart Block. A conduction disorder is a problem with the electrical system that makes your heart beat and controls its rate and rhythm. This system is called the cardiac conduction system. Normally, the electrical signal that makes your heart beat travels from the top of your heart to the bottom The electrical conduction system of the heart is responsible for the EKG tracing you see on a patient. In order to be able to analyze a rhythm strip, you must first learn how the electrical system of the heart works. As I've said many times before, this was my least favorite thing learning in nursing school Your heart beats as a result of the generation and conduction of electrical impulses. Cardiac conduction is the rate at which the heart conducts electrical impulses. These impulses cause the heart to contract and then relax. The constant cycle of heart muscle contraction followed by relaxation causes blood to be pumped throughout the body
