| cardiac souffle | A soft puffing heart murmur. (05 Mar 2000) |
|---|---|
| cardiac sound | 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) |
| cardiac standstill | <cardiology> Cardiac standstill or arrest, absence of a heartbeat. Synonym: Beau's syndrome. (18 Nov 1997) |
| cardiac surgical procedures | Surgery performed on the heart. (12 Dec 1998) |
| cardiac symphysis | Adhesion between the parietal and visceral layers of the pericardium. (05 Mar 2000) |
| cardiac syncope | Fainting with unconsciousness of any cardiac cause. (05 Mar 2000) |
| cardiac 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) |
| cardiac tube | The primitive tubular heart in the embryo, before its division into chambers. (05 Mar 2000) |
| cardiac valve prosthesis | See: valve. (05 Mar 2000) |
| cardiac valvular incompetence | Failure of a valve to perform its fundamental function: insurance of one-way flow; manifested by regurgitation of blood in the opposite direction when the valve is supposed to be closed. (05 Mar 2000) |
| cardiac veins | See: anterior cardiac veins, great cardiac vein, middle cardiac vein, venae cordis minimae. (05 Mar 2000) |
| cardiac volume | The volume of the heart, usually relating to the volume of blood contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is stroke volume. (12 Dec 1998) |
| great cardiac vein | <anatomy, vein> Begins at the apex of the heart (where it anastomoses with the middle cardiac vein), runs first with the anterior interventricular artery as it ascends the anterior interventricular groove, then turns to the left as it approaches or reaches the coronary groove to run with the circumflex branch of the left coronary artery; it merges with the oblique vein of the left atrium to form the coronary sinus. Synonym: vena cordis magna, left coronary vein, vena cardiaca magna. (05 Mar 2000) |
| middle cardiac vein | <anatomy, vein> Begins at the apex of the heart (where it anastomoses with the great cardiac vein), and ascends within the posterior interventricular sulcus to the coronary sinus. Synonym: vena cordis media, inferior cardiac vein. (05 Mar 2000) |
| middle cervical cardiac nerve | <anatomy, nerve> One of the cardiopulmonary splanchnic nerves conveying postsynaptic sympathetic fibres running downward, from the middle cervical ganglion along the subclavian artery (on the left) or the brachiocephalic (on the right side) to join the cardiac plexus. Synonym: nervus cardiacus cervicalis medius. (05 Mar 2000) |
