| nontransmural myocardial infarction | Necrosis of heart muscle that fails to extend from the endocardium to the epicardium, often erroneously considered relatively benign. (05 Mar 2000) |
|---|---|
| diaphragmatic myocardial infarction | Infarction in which the inferior or diaphragmatic wall of the heart is involved, producing indicative changes in leads II, III, and aVF in the electrocardiogram. Synonym: diaphragmatic myocardial infarction. (05 Mar 2000) |
| inferior myocardial infarction | Infarction in which the inferior or diaphragmatic wall of the heart is involved, producing indicative changes in leads II, III, and aVF in the electrocardiogram. Synonym: diaphragmatic myocardial infarction. (05 Mar 2000) |
| inferolateral myocardial infarction | Infarction involving the inferior and lateral surfaces of the heart and producing indicative changes in the electrocardiogram in leads II, III, aVF, V5, and V6. (05 Mar 2000) |
| ischemic preconditioning, myocardial | Exposure of myocardial tissue to brief, repeated periods of vascular occlusion in order to render the myocardium resistant to the deleterious effects of ischemia or reperfusion. The period of pre-exposure and the number of times the tissue is exposed to ischemia and reperfusion vary, the average being 3 to 5 minutes. (12 Dec 1998) |
| through-and-through myocardial infarction | Infarction that involves the whole thickness of the heart muscle from endocardium to epicardium. Synonym: through-and-through myocardial infarction. (05 Mar 2000) |
| transmural myocardial infarction | Infarction that involves the whole thickness of the heart muscle from endocardium to epicardium. Synonym: through-and-through myocardial infarction. (05 Mar 2000) |
| lateral myocardial infarction | Infarction involving only the lateral wall of the heart, producing indicative electrocardiographic changes confined to leads I, aVL, V5, and V6. (05 Mar 2000) |
| alactic oxygen debt | That part of the oxygen debt that is not lactacid oxygen debt; during recovery, stores of ATP and creatine phosphate must be replenished by oxidative metabolism, and a small amount of oxygen is also needed to restore the normal oxyhemoglobin levels throughout the circulating blood. (05 Mar 2000) |
| alveolar-arterial oxygen difference | The difference or gradient between the partial pressure of oxygen in the alveolar spaces and the arterial blood: P(A-a)02. Normally in young adults this value is less than 20 mm Hg. See: alveolar gas equation. (05 Mar 2000) |
| arteriovenous oxygen difference | <physiology> The difference in the oxygen content (in ml per 100 ml blood) between arterial and venous blood. (05 Mar 2000) |
| biochemical oxygen demand | The amount of oxygen aerobicorganisms need to carry out oxidative metabolism in watercontaining organic matter, such as sewage. (09 Oct 1997) |
| carbon-oxygen ligases | <enzyme> Enzymes that catalyze the joining of two molecules by the formation of a carbon-oxygen bond. Registry number: EC 6.1 (12 Dec 1998) |
| carbon-oxygen lyases | <enzyme> Enzymes that catalyze the cleavage of a carbon-oxygen bond by means other than hydrolysis or oxidation. Registry number: EC 4.2 (12 Dec 1998) |
| reactive oxygen species | Reactive intermediate oxygen species including both radicals and non-radicals. These substances are constantly formed in the human body and have been shown to kill bacteria and inactivate proteins, and have been implicated in a number of diseases. Scientific data exist that link the reactive oxygen species produced by inflammatory phagocytes to cancer development. (12 Dec 1998) |
