| low density lipoprotein | <biochemistry> A lipoprotein substances (combination of a fat and a protein) which acts as a carrier for cholesterol and fats in the bloodstream. High levels of low density lipoprotein are considered a positive risk factor for the development of coronary artery disease. Less than 130 mg/dl is desirable, 130 to 159 mg/dl is borderline high, over 160 is considered high. Acronym: LDL (10 Jan 1998) |
| low density lipoprotein receptor | <biochemistry> A cell surface protein that mediates the endocytosis of low density lipoprotein by cells. Genetic defects in low density lipoprotein receptors lead to abnormal serum levels of low density lipoprotein and hypercholesterolaemia. (16 Mar 1998) |
| low-density lipoprotein receptors | Receptors on the surface of cells, especially liver cells, which bind to low density lipoprotein and promote clearance of LDL from the plasma. (05 Mar 2000) |
| A-H interval | The time from the initial rapid deflection of the atrial wave to the initial rapid deflection of the His bundle (H) potential; it approximates the conduction time through the A-V node (normally 50-120 msec). (05 Mar 2000) |
| A-N interval | The time between onset of the atrial deflection and the nodal potential (normally 40-100 msec). (05 Mar 2000) |
| atriocarotid interval | An obsolete term for the time between the beginning of the atrial and that of the carotid waves in a tracing of the jugular pulse. (05 Mar 2000) |
| atrioventricular interval | The time between depolarisation of the atria and of the ventricle. Synonym: atrioventricular interval. (05 Mar 2000) |
| auriculoventricular interval | The time between depolarisation of the atria and of the ventricle. Synonym: atrioventricular interval. (05 Mar 2000) |
| A-V interval | The time from the beginning of atrial systole to the beginning of ventricular systole as measured from pressure pulses or cardiac volume curves in animals, or from the electrocardiogram in humans. (05 Mar 2000) |
| BH interval | The duration of the His bundle deflections (normally 15-20 msec). (05 Mar 2000) |
| cardioarterial interval | The time between the apex beat of the heart and the radial pulse beat. (05 Mar 2000) |
| P-A interval | The time from onset of the P wave to the initial rapid deflection of the A wave in the His bundle electrogram (normally 25-45 msec); it represents the intra-atrial conduction time. (05 Mar 2000) |
| R-R interval | The time elapsing between two consecutive R waves in the electrocardiogram. (05 Mar 2000) |
| P-J interval | The time elapsing from the beginning of the P wave to the end of the QRS complex (J for junction between QRS and S-T segment) in the electrocardiogram. (05 Mar 2000) |
