| third heart sound | Occurs in early diastole and corresponds with the end of the first phase of rapid ventricular filling; normal in children and younger people but abnormal in others. Synonym: third sound. (05 Mar 2000) |
|---|---|
| three-chambered heart | Congenital abnormality in which there may be a single atrium with two ventricles or a single ventricle with two atria. Rudimentary parts of the atrial and ventricular septa may be present but are incompetent to prevent a virtual single chamber in either case. (05 Mar 2000) |
| tiger heart | A fatty degenerated heart in which the fat is disposed in the form of broken stripes in the subendocardial myocardium. (05 Mar 2000) |
| egg-on-its-side heart | <radiology> Marked cardiomegaly, typical of transposition of the great vessels (TGV), also called apple on a string (12 Dec 1998) |
| electrical alternation of heart | A disorder in which the ventricular or atrial complexes or both are regular in time but of alternating pattern; detected by electrocardiography. The P, QRS, T, QRS-T, or P-QRST alternate singly or in combination. (05 Mar 2000) |
| electrical heart position | A description of the heart's assumed electrical habitus based upon the form of the QRS complexes in leads aVL, aVF, V1, and V6. Sometimes loosely (and inaccurately) used to describe the frontal plane electric axis. Synonym: heart position. (05 Mar 2000) |
| tobacco heart | Cardiac irritability marked by irregular action, palpitation, and sometimes pain, believed to occur as a result of the excessive use of tobacco. (05 Mar 2000) |
| Jarvik artificial heart | A pneumatic artificial heart. (05 Mar 2000) |
| eyeball-heart reflex | Slowing of the heart rate due to the vagal effects of compressing an eyeball. Synonym: eyeball compression reflex. (05 Mar 2000) |
| false-heart | Hollow or unsound at the core; treacherous; deceitful; perfidious. Source: Websters Dictionary (01 Mar 1998) |
| fatty heart | Fatty degeneration of the myocardium, accumulation of adipose tissue on the external surface of the heart with occasional infiltration of fat between the muscle bundles of the heart wall. Synonym: cor adiposum. (05 Mar 2000) |
| univentricular heart | An anomaly in which all blood flows through one ventricle or in which the arterioventricular valves are committed to empty into only one chamber in the ventricular mass. (05 Mar 2000) |
| fibrous ring of heart | One of four fibrous rings that surround atrioventricular and arterial orifices of the heart, providing attachment for the valve leaflets and maintaining patency of the orifice. As part of the fibrous skeleton of the heart, the fibrous rings also provide origin and insertion for the myocardium. Synonym: annulus fibrosus cordis, annulus fibrosus, coronary tendon, fibrous ring, Lower's ring. (05 Mar 2000) |
| fibrous skeleton of heart | A complex framework of dense collagen forming four fibrous rings (annuli fibrosi), which surround the ostia of the valves, a right and left fibrous trigone, formed by connecting the rings, and the membranous portions of the interatrial and interventricular septa; it is found in association with the base of the ventricles, i.e., at the level of the coronary sulcus; its functions include: 1) contributing reinforcement of the valvular ostia while providing attachment for the leaflets and cusps of the valves; 2) providing origin and insertion for the myocardium; and 3) serving as a sort of electrical "insulator," separating the electrically conducted impulses of the atria and ventricles and providing passage for the common atrioventricular bundle of conductive tissue through the right fibrous trigone and membranous interventricular septum. Synonym: cardiac fibrous skeleton, cardiac skeleton, skeleton of heart. (05 Mar 2000) |
| fibrous trigones of heart | See: right fibrous trigone, left fibrous trigone. (05 Mar 2000) |
