adj. Abbr. A-V

Of or relating to the atria and the ventricles of the heart.

atrioventricular (AV)

[ā′trē·ōventrik′yələr]

Etymology: L, atrium, hall, ventriculus

pertaining to a connecting conduction event or anatomic structure between the atria and ventricles.

atrioventricular [a″tre-o-ven-trik´u-ler]

pertaining to or connecting an atrium and ventricle of the heart.

atrioventricular

pertaining to an atrium and ventricle of the heart.

accessory tract atrioventricular conduction

see accessory tract atrioventricular conduction.

atrioventricular block

see atrioventricular heart block.

atrioventricular bundle

bundle of His.

common atrioventricular canal

a congenital cardiac defect in which both sides of the heart share the same atrioventricular orifice. Called also persistent atrioventricular canal, atrioventricularis communis.

atrioventricular node

a mass of cardiac muscle fibers (Purkinje fibers) lying on the right lower part of the interatrial septum of the heart. Its function is the transmission of the cardiac impulse from the sinoatrial node to the muscular walls of the ventricles. The conductive system is organized so that transmission is slightly delayed at the atrioventricular node, thus allowing time for the atria to empty their contents into the ventricles before the ventricles begin to contract.

partitioning atrioventricular canal

during embryological development partitioning of the cardiac chambers and their orifices may be incomplete, leading to fatal cardiac defects, e.g. persistent atrioventricular chamber.

persistent common atrioventricular canal

see atrioventricularis communis.

atrioventricular stenosis

left and right atrioventricular stenosis are recorded; the former is an acyanotic defect, the latter is more serious and a cyanotic defect.

atrioventricular trunk

see bundle of His.

atrioventricular valvular disease

may be identifiable on finding of systolic murmur (incompetent valve) or diastolic murmur (stenotic valve) over the apex of the heart with maximum audibility over the left or right sides, depending on the side involved.
