| A.I. | aortic incompetence |
| LAA | 2--Left Atrial Appendage |
| A | Atrial |
| AF | A-atrial fibrillation |
| chronotropic | <pharmacology> Affecting the time or rate, as the rate of contraction of the heart. Origin: Gr. Tropikos = turning (18 Nov 1997) |
|---|---|
| aortic incompetence | Defective closure of the aortic valve permitting regurgitation into the left ventricle during diastole. (05 Mar 2000) |
| cardiac incompetence | Inability of the ventricles to pump out the blood returning to the atria fast enough to prevent an abnormal rise in atrial pressure or to pump sufficient blood to maintain normal circulatory function. (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) |
| valvular incompetence | A leaky state of one or more of the cardiac valves, the valve not closing tightly and blood therefore regurgitating through it. Synonym: valvular incompetence, valvular insufficiency. (05 Mar 2000) |
| relative incompetence | Imperfect closure of a cardiac valve, in consequence of excessive dilation of the corresponding cavity of the heart. (05 Mar 2000) |
| cervix incompetence | Habitual abortion in which painless bloodless dilatation of the cervix in the second trimester of pregnancy is followed by rupture of membranes and expulsion of a foetus so immature that it usually dies. (12 Dec 1998) |
| mitral incompetence | <cardiology> The back flow of blood from the left ventricle to the left atrium through a defective mitral bicuspid valve. The most common cause for mitral regurgitation is rheumatic fever. Other causes include: myocardial infarction, massive calcification of the mitral annulus (in the elderly), lupus, rheumatoid arthritis, infectious endocarditis and ankylosing spondylitis. (13 Nov 1997) |
| muscular incompetence | Imperfect closure of an anatomically normal cardiac valve, in consequence of defective action of its papillary muscles. (05 Mar 2000) |
| pulmonary incompetence | Defective closure of the pulmonic valve permitting regurgitation into the right ventricle during diastole. (05 Mar 2000) |
| pyloric incompetence | A patulous state or want of tone of the pylorus that allows the passage of food into the intestine before gastric digestion is completed. (05 Mar 2000) |
| incompetence | Physical or mental inadequacy or insufficiency. Origin: L. Competens = sufficient (13 Nov 1997) |
| tricuspid incompetence | Defective closure of the tricuspid valve permitting regurgitation into the right atrium during systole. (05 Mar 2000) |
| arrhythmias, atrial | Abnormal heart rhythm due to electrical disturbances in the atria (the upper chambers of the heart) or the AV node relay station , leading to fast heart beats. Examples of atrial arrhythmias includes atrial fibrillation, atrial flutter, and paroxysmal atrial tachycardia (PAT). (12 Dec 1998) |
| atrial | <anatomy> Pertaining to an atrium. (16 Dec 1997) |
| atrial chronotropic incompetence |
inability to increase the heart rate to levels capable of satisfying the needs of the body.
