| 설명 | 관 혹은 통로에 있는 막과 같은 주름. 내용물의 역류를 막는다. 1.심장판막: 우심방과 우심실사이의 삼첨판, 좌심방과 좌심실사이의 승모판, 우심실과 폐동맥사이의 폐동맥반월판, 좌심실과 대동맥사이의 대동맥반월판이 있다. 2.정맥판막: 정맥에서 발견되는 내막의 작은 첨 혹은 주름. 탄력성이 적어 역류되기 쉬운 정맥혈의 흐름을 역류없이 정상적인 방향으로 지속되도록 해준다. 3.인공판막: 심장판막부족이나 심장판막협착이 있어 더이상 자신의 판막으로는 생존이 불가능할 때 대신 이식하게 되는 인공판막을 말한다. 크게 동물의 조직을 이용한 것과 그렇지 않은 것으로 양분할 수 있다. 동물의 조직을 이용한 것은 주로 돼지나 소의 판막 또는 심외막 등을 이용하며, 그렇지 않은 것은 특수한 금속을 이용하여 만든다. |

| atrioventricular connections | The five distinct and discrete ways in which the atrial chambers may be connected to the ventricles are concordant, discordant, ambiguous, double inlet, and univentricular. (05 Mar 2000) |
|---|---|
| atrioventricular dissociation | Any situation in which atria and ventricles are activated and contract independently, as in complete A-V block, more specifically, the dissociation between atria and ventricles that results from slowing of the atrial pacemaker or acceleration of the ventricular pacemaker at nearly equal (rarely equal) rates, each depolarising its own chamber, thus interfering with depolarisation by the other (interference-dissociation). (05 Mar 2000) |
| atrioventricular extrasystole | An extrasystole arising from the "junctional" tissues, either the A-V node or A-V bundle. Synonym: junctional extrasystole. (05 Mar 2000) |
| atrioventricular gradient | The diastolic pressure difference between the atrium and ventricle. (05 Mar 2000) |
| atrioventricular groove | A groove on the outer surface of the heart marking the division between the atria and the ventricles. Synonym: sulcus coronarius, atrioventricular groove, atrioventricular sulcus, auriculoventricular groove, coronary sulcus. (05 Mar 2000) |
| atrioventricular interval | The time between depolarisation of the atria and of the ventricle. Synonym: atrioventricular interval. (05 Mar 2000) |
| atrioventricular junctional bigeminy | Paired beats, each pair consisting of an A-V nodal extrasystole coupled to a beat of the dominant, usually sinus, rhythm. Synonym: nodal bigeminy. (05 Mar 2000) |
| atrioventricular junctional rhythm | The cardiac rhythm when the heart is controlled by the A-V junction (including node); arising in the A-V junction, the impulse ascends to the atria and descends to the ventricles, each at varying speeds depending on site of the pacemaker. Synonym: A-V junctional rhythm, nodal bradycardia, nodal rhythm. (05 Mar 2000) |
| atrioventricular junctional tachycardia | Tachycardia originating in the A-V junction. Synonym: A-V junctional tachycardia, nodal tachycardia. (05 Mar 2000) |
| atrioventricular nodal branch | The atrioventricular branches or the nodal branches, the small arteries supplying the atrioventricular node; they usually arise from the right coronary artery where it starts to descend the posterior interventricular sulcus. Synonym: ramus nodi atrioventricularis, atrioventricular nodal branch, branch to atrioventricular node. (05 Mar 2000) |
| atrioventricular nodal extrasystole | A premature beat arising from the A-V junction and leading to a simultaneous or almost simultaneous contraction of atria and ventricles. (05 Mar 2000) |
| atrioventricular node | <cardiology> The location in the heart's conduction system, between the atria and the ventricles, which conducts the normal electrical impulse from the atria to the ventricles. (27 Sep 1997) |
| atrioventricular septum | The small part of the membranous septum of the heart just above the septal cusp of the tricuspid valve that separates the right atrium from the left ventricle. Synonym: septum atrioventriculare, pars membranacea septi atriorum. (05 Mar 2000) |
| atrioventricular sulcus | A groove on the outer surface of the heart marking the division between the atria and the ventricles. Synonym: sulcus coronarius, atrioventricular groove, atrioventricular sulcus, auriculoventricular groove, coronary sulcus. (05 Mar 2000) |
| atrioventricular valves | See: tricuspid valve, mitral valve. (05 Mar 2000) |
