| anomalous | Deviating from a general rule, method, or analogy; abnormal; irregular; as, an anomalous proceeding. Origin: L. Anomalus, Gr. Uneven, irregular; priv. + even, same. See Same, and cf. Abnormal. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| anomalous atrioventricular excitation | Ectopic atrial beat conducted to the ventricle. (05 Mar 2000) |
| anomalous complex | A complex in the electrocardiogram differing significantly from the physiologic type in the same lead. (05 Mar 2000) |
| anomalous correspondence | Abnormal correspondence, a condition, frequent in strabismus, in which corresponding retinal points do not have the same visual direction; the fovea of one eye corresponds to an extrafoveal area of the fellow eye. Synonym: abnormal correspondence. (05 Mar 2000) |
| anomalous diffusion | <radiobiology> Diffusion in most plasma devices, particularly tokamaks, is higher than what one would predict from understood causes. The observed, typical diffusion is referred to as anomalous because it has not yet been explained. Anomalous diffusion includes all diffusion which is not due to collisions and geometric effects. While such effects were not understood when the term was coined, and most still are not, diffusion due to well-understood wave phenomena is still 'anomalous'. Classical diffusion and Neo-classical diffusion are the two well-understood diffusion theories, although neither is adequate to fully explain the observed anomalous diffusion. See: entries for classical diffusion and neoclassical diffusion. Anomalous resistivity (09 Oct 1997) |
| anomalous mitral arcade | Short chordae tendineae extending from both papillary muscles to the central portion of the anterior leaflet of the mitral valve and resulting in stenosis or incompetence of the valve. (05 Mar 2000) |
| anomalous trichromatism | A defect in colour perception in which there appears to be an abnormality or deficiency in one of the three primary pigments of the retinal cones. See: protanomaly, deuteranomaly, tritanomaly. (05 Mar 2000) |
| anomalous uterus | A malformed uterus caused by abnormal development or fusion of the paramesonephric ducts. (05 Mar 2000) |
| anomalous viscosity | The viscous behaviour of nonhomogenous fluids or suspensions, e.g., blood, in which the apparent viscosity increases as flow or shear rate decreases toward zero. (05 Mar 2000) |
| total anomalous pulmonary venous return | <radiology> (TAPVR) admixture lesion: cyanosis, increased pulmonary blood flow, must have L to R shunt for survival (e.g., atrial septal defect) associated with, atrial septal defect, asplenia (12 Dec 1998) |
| total or partial anomalous pulmonary venous connections | Connections in which some or all of the pulmonary veins connect to the right atrium or one of its tributaries. (05 Mar 2000) |
| aberrant ventricular conduction | Abnormal intraventricular conduction of a supraventricular beat, especially where surrounding beats are normally conducted. Synonym: ventricular aberration. (05 Mar 2000) |
| accelerated conduction | Any pathologically increased speed of conduction; usually occurs between the atrium and ventricles as in the Wolff-Parkinson-White and Lown-Ganong-Levine syndromes; such accelerated pathways provide the bases for particular forms of reentry tachycardia. (05 Mar 2000) |
| A-H conduction time | 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) |
| air conduction | In relation to hearing, the transmission of sound to the inner ear through the external auditory canal and the structures of the middle ear. (05 Mar 2000) |
| anomalous conduction |
conduction of the sinus impulse over accessory conducting pathways, thus avoiding the delay in passage through the normal atrioventricular node.
