| atrioventricular block |
AV block, impairment of conduction of cardiac impulses from the atria to the ventricles, usually due to a block in the atrioventricular junctional tissue (atrioventricular node, bundle of His, or bundle branches). It is generally subclassified as first, second, or third degree atrioventricular block. Cf. heart b.

| atrium |
In anatomy, the atrium (plural: atria) is the blood collection chamber of a heart. It has a thin-walled structure that allows blood to return to the heart. There is at least one atrium in an animal with a closed circulatory system. In fish, the circulatory system is very simple: a two-chambered heart including one atrium and one ventricle. In vertebrate groups that evolved later, the circulatory system is much more complicated. ...
