|---|---|---|---|
| 설명 | 심장의 수술에 사용되는 기계로서 심장이 수술을 받고 있는 동안 기능을 하지 못하므로 이 기능을 대신 해주는 기계이다. 이것은 대정맥과 대동맥사이에 연결이 되어서 혈액을 강제로 순환시키면서 대정맥에서 온 피에 산소를 공급하여 대동맥으로 돌려 보내는 역할을 한다. 즉 심장과 폐의 역할을 동시에 하는 기계이다. |

|---|---|---|---|
| 설명 | 심장의 원래 기능, 즉 혈액을 말초로 보내는 펌프와 같은 기능이 거의 없어진 상태를 말한다. 피를 보내는 펌프의 역할이 멈추었으므로 심장으로 들어오는 피는 심장으로 들어오지 못하고 정맥속에서 정체하게 된다. 그리하여 혈액의 대부분이 말초의 정맥에 머물게 되어 여러 가지 증상이 나타난다. 특히 허파를 돌아 좌심방으로 들어가야하는 피가 펌프 기능이 없어져서 왼심방에 많은 피가 정체하고 있어서 들어가지 못해서 허파에 고이게 된다. 그러면 허파에 산소와 이산화탄소를 교환하는 기능이 없어져서 숨을 쉬지 못하는 결과를 낸다. 즉 숨이 차고 숨쉬기 힘든 증세가 나타난다. 또 온몸을 순환한 다음에 우심방으로 들어와야하는 피도 우심방으로 들어오지 못해서 말초에 정체하므로 온몸이 붓게 된다. |

| 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) |
| rate, heart | Number of heart beats per minute. The normal resting adult heart beats regularly at an average rate of 60 times per minute. (young children's hearts beat faster). The speed of the heartbeat (heart rate) is governed by the speed of electrical signals from the pacemaker of the heart, the sa node, located in the right atrium (upper chamber of the heart). The electrical signals from the sa node travel across the atria and cause these two upper heart chambers to contract, delivering blood into the lower heart chambers, the ventricles. The electrical signals then pass through the av node to reach the ventricles. Electrical signals reaching the ventricles cause these chambers to contract, pumping blood to the rest of the body, generating the pulse. During rest, the speed of electrical signals originating from the sa node is slow, so the heart beats slowly. During exercise or excitement, the speed of signals from the sa node increases, and the heartbeat quickens. (12 Dec 1998) |
| 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) |
| mechanical alternation of the heart | A disorder in which contractions of the heart are regular but are alternately stronger and weaker. (05 Mar 2000) |
| mechanical heart | Term loosely applied to any mechanical circulatory assist device. (05 Mar 2000) |
