WebbThe AV node serves as a traffic signal, controlling the rate of electrical impulses from the atria allowed to reach the ventricles, limiting the danger of 1 to 1 conduction of fast rhythms from the atrium to the ventricles. AV block is a term to describe abnormal impulse conduction through the AV node. This can be manifest as slower than usual ... Webbslows conduction velocity ensures ventricles have enough time to relax and fill with blood before contraction rapid conductions through AV node can lead to decreased stroke …
WebbThe cardiac conduction system is a specialized network of cells within the heart that generates and conducts electrical impulses, which regulate the rhythmic contractions of the heart. The process begins with the sinoatrial (SA) node, located in the upper right atrium, which serves as the natural pacemaker of the heart. WebbSlow conduction areas and conduction block in the atria are considered pro-arrhythmic conditions. Studies examining the size and distribution of slow...
