| BASH | body acceleration synchronous with heart rate |
|---|---|
| BHR | basal heart rate; benign hypertrophic prostatitis; bronchial hyperreactivity |
| HEHR | highest equivalent heart rate |
| HRA | health record analyst; health risk appraisal; heart rate audiometry; hereditary renal adysplasia; hi... |
| HRF | heart rate fluctuations |
| base of heart | That part of the heart that lies opposite the apex, formed mainly by the left atrium but to a small extent by the posterior part of the right atrium; it is directed backward and to the right and is separated from the vertebral column by the oesophagus and aorta. Synonym: basis cordis. (05 Mar 2000) |
|---|---|
| beer heart | <cardiology, pathology> A weakness of the cardiac muscle which is seen in some chronic alcoholics, may be related to a thiamin deficiency or occur for unknown reasons. Origin: Gr. Pathos = disease (27 Sep 1997) |
| beriberi heart | Heart disease due to thiamine deficiency that may be epidemic or sporadic as characterised by cardiac metabolic damage and myocardial failure, often of the "high output" type, with oedema (except in "dry" beri) and polyneuritis. The term is derived from Singhalese, "I am unable." (05 Mar 2000) |
| biopsy, heart | <investigation, procedure, surgery> A procedure which involves the removal of a small specimen of cardiac muscle tissue for microscopic analysis. This is generally performed at the same time as a cardiac catheterisation or as a very similar, yet separate, procedure. A small piece of heart tissue is taken via a small forceps inserted into the cardiac catheter site (usually threaded through a vein in the neck). This test may reveal the cause of a cardiomyopathy, myocarditis, amyloidosis or a heart transplant rejection. (21 Mar 1998) |
| bony heart | The presence of extensive calcareous patches in the pericardium and walls of the heart, some of which chronically develop bony changes. (05 Mar 2000) |
| box-like heart | <radiology> Ebstein's anomaly, massive cardiomegaly, primarily RA enlargement (12 Dec 1998) |
| brain-heart infusion agar | A medium used for the isolation of fastidious microorganisms, especially fungi. (05 Mar 2000) |
| carcinoid heart disease | Cardiac manifestation of malignant carcinoid syndrome. It is a unique form of fibrosis involving the endocardium, primarily of the right heart. The fibrous deposits tend to cause constriction of the tricuspid and pulmonary valves. (12 Dec 1998) |
| machine, heart-lung | A machine that does the work both of the heart (pump blood) and the lungs (oxygenate the blood). Used, for example, in open heart surgery. Blood returning to the heart is diverted through the machine before returning it to the arterial circulation. Also called a pump-oxygenator. (12 Dec 1998) |
| valvular heart disease | A general term that applies to any abnormality of one of the heart valves, tricuspid, mitral, aortic or pulmonic valves. (27 Sep 1997) |
| venous heart | <anatomy> The right side, including both the atrium and ventricle, of the heart. (05 Mar 2000) |
| ventricles of heart | One of the two lower chambers of the heart. Synonym: ventriculus cordis. (05 Mar 2000) |
| parchment heart | A congenital or acquired condition in which there is thinning of the right ventricular myocardium. Synonym: right ventricular hypoplasia. (05 Mar 2000) |
| vertical heart | Loosely descriptive of the heart's electrical axis when this is directed at approximately +90 |
| partial heart block | Impulses penetrate the atrioventricular junction in some relation to the ventricular rate. Synonym: incomplete atrioventricular block. (05 Mar 2000) |
