| heart rate, foetal | The heart rate of the foetus. The normal range at term is between 120 and 160 beats per minute. (12 Dec 1998) |
|---|---|
| heart rupture | Laceration or tearing of the walls of the heart, of the interatrial or interventricular septum, of the papillary muscles or chordae tendineae, or of any of the valves of the heart. Rupture may be due to a variety of pathological entities, however, the majority are secondary to myocardial infarction (heart rupture, post-infarction). (12 Dec 1998) |
| heart rupture, post-infarction | Rupture of the heart after myocardial infarction. (12 Dec 1998) |
| heart sac | <anatomy> A double membranous sac which envelops and protects the heart. The layer in contact with the heart is referred to as the visceral layer, the outer layer in contact with surrounding organs is the parietal pericardium. In between the two layers is the pericardial space. (27 Sep 1997) |
| heart septal defects | Defects in the cardiac septa, resulting in abnormal communications between the opposite chambers of the heart. (12 Dec 1998) |
| heart septal defects, atrial | Defects in the septum between the atria of the heart, due to failure of fusion between either the septum secundum or the septum primum and the endocardial cushions. (12 Dec 1998) |
| heart septal defects, ventricular | Congenital defects in the septum between the cardiac ventricles, most often due to failure of the bulbar septum to completely close the interventricular foramen. (12 Dec 1998) |
| heart septum | The thin membranous structure between the two heart atria or the thick muscular structure between the two heart ventricles. (12 Dec 1998) |
| heart sounds | The sounds heard over the cardiac region produced by the functioning of the heart. There are four distinct sounds: the first occurs at the beginning of systole and is heard as a "lubb" sound; the second is produced by the closing of the aortic and pulmonary valves and is heard as a "dupp" sound; the third is produced by vibrations of the ventricular walls when suddenly distended by the rush of blood from the atria; and the fourth is produced by atrial contraction and ventricular filling but is rarely audible in the normal heart. The physiological concept of heart sounds is differentiated from the pathological heart murmurs. (12 Dec 1998) |
| heart stroke | Impact of the apex of the heart against the wall of the chest. Synonym: angina pectoris. (05 Mar 2000) |
| heart tamponade | Interference with the venous return of blood to the heart due to an extensive accumulation of blood in the pericardium (pericardial effusion). Tamponade may occur as a complication of dissecting thoracic aneurysm, pericarditis, renal failure, acute myocardial infarction, hypothyroidism, autoimmune disease (for example lupus), chest trauma or a malignancy. Fluid in the pericardial sac is demonstrated by echocardiogram. Treatment involves the emergent removal of the fluid. This may be accomplished by a needle aspiration technique or emergency surgery (pericardial window). (27 Sep 1997) |
| heart tones | The sounds heard over the cardiac region produced by the functioning of the heart. There are four distinct sounds: the first occurs at the beginning of systole and is heard as a "lubb" sound; the second is produced by the closing of the aortic and pulmonary valves and is heard as a "dupp" sound; the third is produced by vibrations of the ventricular walls when suddenly distended by the rush of blood from the atria; and the fourth is produced by atrial contraction and ventricular filling but is rarely audible in the normal heart. The physiological concept of heart sounds is differentiated from the pathological heart murmurs. (12 Dec 1998) |
| heart transplantation | The transference of a heart from one human or animal to another. (12 Dec 1998) |
| heart valve | <anatomy> A term used to describe anyone of the main 4 valves of the heart: tricuspid, mitral, aortic or pulmonic valves. Mitral valve separates left atrium and left ventricle, pulmonic valve separates pulmonary vein and left atrium, tricuspid valve separates right atrium and right ventricle, aortic valve separates left ventricle and the aorta (27 Sep 1997) |
| heart valve prolapse | Displacement of the valves of the heart. (12 Dec 1998) |

| hearing aid |
A hearing aid is a device used to help the hard-of-hearing hear sounds better. In the past, a funnel-like amplification cone, called an "ear trumpet" or "ear horn", was used. Now, however, the most common style is a small electronic device that fits into the wearer's ear. The first variety of this device had a rectangular battery pack connected by a thin wire, intended to be held in a pocket. ...
