| tachycardia, ectopic atrial | A tachycardia originating in the atrial myocardium and characterised by rates between 135 and 175 beats per minute. (12 Dec 1998) |
| tachycardia, ectopic junctional | A tachycardia arising in the conduction tissues surrounding the atrioventricular node. It usually occurs during myocardial infarction, after heart surgery, or in digitalis intoxication. The rate may range from 140 to 250 beats per minute. (12 Dec 1998) |
| ectopic | Pertaining to or characterised by ectopia. (18 Nov 1997) |
| ectopic ACTH syndrome | <syndrome> The association of Cushing's syndrome with a non-pituitary neoplasm, usually a lung carcinoma that produces ACTH. (05 Mar 2000) |
| ectopic decidua | Decidual cells which may be found in the cervix, appendix, or areas other than the endometrium. (05 Mar 2000) |
| ectopic eyelash | The condition in which the eyelash's grow from the eyelid at a site other than the lid margin. Synonym: canities poliosis. (05 Mar 2000) |
| ectopic heartbeat | Any heartbeat that occurs out of the normal sinus rhythm of the heart. Examples include premature ventricular contractions and atrial premature contractions. Premature beats can be exacerbated by the use of stimulants such as caffeine, smoking, alcohol, decongestants and cocaine. (27 Sep 1997) |
| ectopic hormone | A hormone formed by tissue outside the normal endocrine site of production; e.g., adrenocorticotropic hormone produced by a bronchogenic carcinoma. Synonym: inappropriate hormone. (05 Mar 2000) |
| ectopic impulse | An electrical impulse from an area of the heart other than the sinus node. (05 Mar 2000) |
| ectopic pacemaker | Any pacemaker other than the sinus node. (05 Mar 2000) |
| ectopic pairing | Pairing of heterochromatin randomly, without regard to whether they are homologous. (09 Oct 1997) |
| ectopic pancreas | <radiology> Site: stomach (most common), small bowel, Meckel diverticulum, gallbladder, spleen prevalence: 10% at autopsy, 1:500 at operation (12 Dec 1998) |
| ectopic pinealoma | <tumour> An obsolete term for an undifferentiated neoplasm resembling a pinealoma, usually found near the pituitary gland; believed by some to be an undifferentiated teratoma. (05 Mar 2000) |
