| sinoatrial node | <anatomy, cardiology, physiology> The impulse generating (pacemaker) tissue located in the right atrium, under the epicardium at the upper end of the sulcus terminalis. The specialised cardiac muscle fibres generate cardiac impulses that normally acts as the pacemaker of the cardiac conduction system. Normal impulses start in the sinoatrial node and are transmitted to the ventricles, through the atrioventricular node and into the bundle of His. Synonym: nodus sinuatrialis, atrionector, Flack's node, Keith and Flack node, Keith's node, Koch's node, sinoatrial node, sinus node. (20 Jun 2000) |
|---|
| sinoatrial | <anatomy> Relating to the sinus venosus and the right atrium of the heart. Synonym: sinuatrial. (20 Jun 2000) |
|---|---|
| sinoatrial block | <cardiology, physiology> Disturbance of heart conduction in which the atrial response is delayed or omitted because of partial or complete interference with the propagation of impulses from the sinoatrial node to the atria. (12 Dec 1998) |
| sinoatrial chamber | <anatomy> The common chamber formed by the single embryonic atrium and the right and left horns of the sinus venosus. (20 Jun 2000) |
| sinoatrial conduction time | <cardiology, physiology> The time required for an impulse to travel from the sinoatrial node to the atrium; estimated indirectly during asystole by halving the average interval from the premature beat to the following normal sinus beat of the atrium. (05 Mar 2000) |
| sinoatrial nodal artery | <anatomy, artery> A branch usually of the right coronary artery that supplies the sinuatrial node. Synonym: sinus node artery. (05 Mar 2000) |
| sinoatrial recovery time | <cardiology, physiology> Interval from the last paced P wave to the first succeeding spontaneous P wave (after 2 to 5 minutes of right atrial pacing at 120 to 140 beats per minute, and when expressed as percentage of control cycle length, it normally ranges from 115 to 159%). (05 Mar 2000) |
| tachycardia, sinoatrial nodal reentry | A tachycardia arising from the sinus node region and characterised by rates between 115 and 140 beats per minute. It is paroxysmal rather than constant. (12 Dec 1998) |
| angiofollicular mediastinal lymph node hyperplasia | Solitary masses of lymphoid tissue containing concentric perivascular aggregates of lymphocytes, occurring usually in the mediastinum or hilar region of young adults; similar changes have been reported outside the mediastinum and, if associated with interfollicular sheets of plasma cells, may progress to lymphoma or plasmacytoma. Synonym: angiofollicular mediastinal lymph node hyperplasia, Castleman's disease. (05 Mar 2000) |
| anterior tibial lymph node | A small inconstant lymph node in front of the interosseous membrane along the upper part of the anterior tibial vessels. Synonym: nodus tibialis anterior, anterior tibial node. (05 Mar 2000) |
| anterior tibial node | A small inconstant lymph node in front of the interosseous membrane along the upper part of the anterior tibial vessels. Synonym: nodus tibialis anterior, anterior tibial node. (05 Mar 2000) |
| artery to atrioventricular node | 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) |
| artery to the sinuatrial node | Ascending atrial branch, usually (55%) arising from the anterior stem of the right coronary artery (but 35-45% arising from the circumflex branch of the left coronary artery), which runs around the base of the superior vena cava to reach the sinuatrial node. Synonym: ramus nodi sinuatrialis arteriae coronaria dextra, branch to sinuatrial node, sinuatrial nodal branch of right coronary artery, sinuatrial node artery. (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) |
| A-V 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) |
| axillary node | <anatomy> The lymph nodes in the axilla (underarm) that are cut out and examined during surgery to see if the cancer has spread past the breast. The number of nodes in this area varies. (09 Oct 1997) |
