| denture, complete, upper | A complete denture replacing all the natural maxillary teeth and associated maxillary structures. It is completely supported by the oral tissue and underlying maxillary bone. (12 Dec 1998) |
| Freund's complete adjuvant | Water-in-oil emulsion of antigen, to which killed mycobacteria or tuberculosis bacteria are added. (05 Mar 2000) |
| ambiguous atrioventricular connections | Connections in which half the atrioventricular junction is connected concordantly and the other half is discordantly connected. (05 Mar 2000) |
| anomalous atrioventricular excitation | Ectopic atrial beat conducted to the ventricle. (05 Mar 2000) |
| anterior cusp of atrioventricular valve | The anterior leaflet or valvule of either the tricuspid or mitral valves. Synonym: cuspis anterior valvae atrioventricularis dextrae/sinistrae. (05 Mar 2000) |
| artery to atrioventricular node | The atrioventricular branches or the nodal branches, the small arteries supplying the atrioventricular node; they usually arise from the right coronary artery where it starts to descend the posterior interventricular sulcus. Synonym: ramus nodi atrioventricularis, atrioventricular nodal branch, branch to atrioventricular node. (05 Mar 2000) |
| atrioventricular | <anatomy, cardiology> Pertaining to an atrium of the heart and to a ventricle. (16 Dec 1997) |
| atrioventricular band | The bundle of modified cardiac muscle fibres that begins at the atrioventricular node as the trunk of the atrioventricular bundle and passes through the right atrioventricular fibrous ring to the membranous part of the interventricular septum where the trunk divides into two branches, the right crus of the atrioventricular bundle and the left crus of the atrioventricular bundle; the two crura ramify in the subendocardium of their respective ventricles. Synonym: fasciculus atrioventricularis, atrioventricular band, Gaskell's bridge, His' band, His' bundle, bundle of His, Keith's bundle, Kent's bundle, Kent-His bundle, ventriculonector. (05 Mar 2000) |

(05 Mar 2000) |
| atrioventricular canal | The canal in the embryonic heart leading from the common sinuatrial chamber to the ventricle. (05 Mar 2000) |
| atrioventricular canal cushions | A pair of mounds of embryonic connective tissue covered by endothelium, bulging into the embryonic atrioventricular canal; located one dorsally and one ventrally, they grow together and fuse with each other and with the lower edge of the septum primum, dividing the originally single canal into right and left atrioventricular orifices. Synonym: endocardial cushions. (05 Mar 2000) |
| atrioventricular conduction | Forward conduction of the cardiac impulse from atria to ventricles via the A-V node or any bypass tract, represented in the electrocardiogram by the P-R interval. P-H conduction time is from the onset of the P wave to the first high frequency component of the His bundle electrogram (normally 119 ± 38 msec); A-H conduction time is from the onset of the first high frequency component of the atrial electrogram to the first high frequency component of the His bundle electrogram (normally 92 ± 38 msec); P-A conduction time is from the onset of the P wave to the onset of the atrial electrogram (normally 27 ± 18 msec). (05 Mar 2000) |
| atrioventricular conduction abnormalities | <cardiology, physiology> Any condition which involves abnormal (blocked, delayed or aberrant) electrical conduction through the atrioventricular node (for example atrioventricular block). Some medications may precipitate atrioventricular conduction abnormalities. (02 Jan 1998) |
| atrioventricular connections | The five distinct and discrete ways in which the atrial chambers may be connected to the ventricles are concordant, discordant, ambiguous, double inlet, and univentricular. (05 Mar 2000) |
