Overview of the Cardiac Conduction System The cardiac conduction system is a network of specialized cells responsible for the initiation and co-ordination of the heartbeat. Relative to the myocytes responsible for regulating cardiac contraction in a normal heart (~1 × 109), the cells that make ...
In the normal rhythm of the human heart an electrical impulse originates within the sinus node and courses by way of internodal pathways to the AY (atrioventricular) junction where it enters the AV node and passes to the His bundle for distribution through its right and left bundle branches ...
The heart conduction system is made up of cells, nodes, and signals that help your heart to beat. In fact, the cardiac conduction system is responsible for our heart beating around 2.5 billion times during the average human lifespan. The conduction system, also called the cardiac electrical sy...
Surgical heart block has assumed a major experimental and clinical position in the overall picture of heart block. Anatomical studies of the conduction system have revealed moderately consistent patterns in various cardiac anomalies, but... HL Gadboys,RS Litwak - 《Progress in Cardiovascular Diseases》...

conductionsystem. The primary function of the ventricular conduction system is to synchronize the segmental activation of the ventricles, optimizing energy demand. In a normal heart, theventricular contractionstarts at the apex of the heart and moves with a twistingmotionto the side walls, reaching ...
