| Einarson's gallocyanin-chrome alum stain | <technique> A method for staining both RNA and DNA a deep blue; with proper controls, nucleic acid content of stained cells and nuclei may be estimated by cytophotometry; also useful for Nissl substance. (05 Mar 2000) |

| einstein | A unit of energy equal to 1 mol quantum, hence to 6.0221367 × 1023 quanta. The value of einstein, in kJ, is dependent upon the wavelength. Origin: A. Einstein, German-born theoretical physicist and Nobel laureate in U.S., 1879-1955 (05 Mar 2000) |
| einsteinium | <chemical> Einsteinium. A man-made radioactive actinide with atomic symbol es, atomic number 99, and atomic weight 252. Its known isotopes range in mass number from 243-246. Its valence can be +2 or +3. Einsteinium was originally discovered in the debris from a thermonuclear explosion in 1952. Chemical name: Einsteinium (12 Dec 1998) |
| Einthoven's equation | In the electrocardiogram the potential of any wave or complex in lead II is equal to the sum of the potentials of leads I and III. Synonym: Einthoven's equation. (05 Mar 2000) |
| Einthoven's law | In the electrocardiogram the potential of any wave or complex in lead II is equal to the sum of the potentials of leads I and III. Synonym: Einthoven's equation. (05 Mar 2000) |
| Einthoven's triangle | An imaginary equilateral triangle with the heart at its centre, its equal sides representing the three standard limb leads of the electrocardiogram. (05 Mar 2000) |
| Einthoven, Willem | <person> Dutch physiologist and Nobel laureate, 1860-1927. See: Einthoven's equation, Einthoven's law, Einthoven's string galvanometer, Einthoven's triangle. (05 Mar 2000) |
| Eisenlohr's syndrome | <syndrome> Numbness and weakness in the extremities, paralysis of the lips, tongue, and palate, and dysarthria. (05 Mar 2000) |
| Eisenlohr, Carl | <person> German physician, 1847-1896. See: Eisenlohr's syndrome. (05 Mar 2000) |
| eisenmenger complex | Defect of the interventricular septum with severe pulmonary hypertension, hypertrophy of the right ventricle, and latent or overt cyanosis. (12 Dec 1998) |
| eisenmenger syndrome | <radiology> Pulmonary aterial hypertension, heart size normal (or slightly increased), big central pulmonary arteries with abrupt tapering, bidirectional or reversed cardiac shunt (12 Dec 1998) |
| Eisenmenger's complex | The combination of ventricular septal defect with pulmonary hypertension and consequent right-to-left shunt through the defect, with or without an associated overriding aorta. Synonym: Eisenmenger's defect, Eisenmenger's disease, Eisenmenger's tetralogy. (05 Mar 2000) |
| Eisenmenger's defect | The combination of ventricular septal defect with pulmonary hypertension and consequent right-to-left shunt through the defect, with or without an associated overriding aorta. Synonym: Eisenmenger's defect, Eisenmenger's disease, Eisenmenger's tetralogy. (05 Mar 2000) |
| Eisenmenger's disease | The combination of ventricular septal defect with pulmonary hypertension and consequent right-to-left shunt through the defect, with or without an associated overriding aorta. Synonym: Eisenmenger's defect, Eisenmenger's disease, Eisenmenger's tetralogy. (05 Mar 2000) |
| Eisenmenger's syndrome | <syndrome> Cardiac failure with significant right to left shunt producing cyanosis due to higher pressure on the right side of the shunt. Usually due to the Eisenmenger complex, a ventricular septal defect with right ventricular hypertrophy, severe pulmonary hypertension, and frequent straddling of the defect by a misplaced aortic root.
