atrioventrikulaarne
Atrioventrikulaarne refers to the relationship or connection between the atria and the ventricles of the heart. The atria are the two upper chambers of the heart, and the ventricles are the two lower chambers. The atrioventricular valves, specifically the tricuspid valve between the right atrium and right ventricle, and the mitral valve (or bicuspid valve) between the left atrium and left ventricle, are crucial structures that ensure unidirectional blood flow from the atria to the ventricles.
In normal cardiac function, electrical impulses originating in the sinoatrial node travel to the atria, causing
Disruptions in the atrioventricular system can lead to various cardiac arrhythmias, such as heart block, where
