Learn about the intrinsic conduction system, including the SA node, AV node, the bundle of His, bundle branches, and Purkinje fibers, and discover its role in heart contraction coordination. Related to this QuestionWhich of the f...
1 of 2 electrical conduction in the heartElectrical conduction in the heart in healthy individuals is controlled by pacemaker cells in the sinoatrial node. Electrical impulses are conducted from the sinoatrial node to the atrioventricular node and bundle of His, through the bundle branches, and into...

(3) the atrioventricular bundle of His, which extends from the atrioventricular node to the interventricular septum. The bundle of His divides into right and left branches, which spread out in the ventricular myocardium in the form of Purk-inje fibers. The cells of the conduction system generate...
The relationships among the His bundle, the origin of both bundle branches, and the interventricular (IV) septum were examined histologically in 32 human hearts, and the entire bundle branch systems were delineated in 13 of these. The His bundle in five hearts traversed the right IV septal cres...

bundle is also known as the Bundle of His. It contains severalnervecells and receives electrical input from the atrioventricular node. The bundle has two branches: left and right. They send electrical signals to the left and right ventricles found in the chamber at the bottom of your heart. ...

The meaning of HEART BLOCK is incoordination of the heartbeat in which the atria and ventricles beat independently and which is marked by decreased cardiac output.
