atrialadj.

Brit.

/ˈeɪtrɪəl/, U.S.

/ˈeɪtriəl/

Origin: Either (i) formed within English, by derivation. Or (ii) a borrowing from Latin, combined with an English element. Etymons: atrium n., -al suffix¹; Latin ātrium , -al suffix¹.

Etymology: < atrium n. or its etymon classical Latin ātrium + -al suffix¹.

Of or relating to an atrium or atria (in various, mainly anatomical, senses); spec. of or relating to the atria of the heart (cf. auricular adj. 5).

1859 Philos. Trans. 1858 (Royal Soc.) 148 ii. 843 This atrial membrane is found in the most rudimentary condition in the Polyzoa.

1869 T. H. Huxley Introd. Classif. Animals 31 In these animals [sc. Ascidioida] there is an atrial system.

1913 Brit. Med. Jrnl. 21 Dec. 90/1 The secondary wave of stasis seen in repose in the atrial wave disappears after fatigue.

1930 H. G. Newth Marshall & Hurst's Junior Course Pract. Zool. (ed. 11) xi. 195 The inner surface of each gill-slit is lined by columnar ciliated cells, which maintain a continuous stream of water through the gill-slits from the pharynx to the atrial cavity.

1961 Lancet 22 July 187/2 Continuous monitoring of the atrial pressure would provide early warning of a dangerous rise.

1991 R. B. Javellana Wood & Stone for God's Greater Glory 212/1 A similar atrial plan is found in a 25 Aug. 1826 copy of a map of Cebu.

2003 N.Y. Times 9 Sept. (Washington Final ed.) d6/3 They have closed atrial septal defects, openings in the wall between the heart's upper chambers.

Compounds

atrial fibrillation n. Medicine irregular, uncoordinated twitching or quivering (as opposed to regular contraction) of the atria of the heart, typically associated with irregular and often rapid ventricular contraction.

ΚΠ

1910 Jrnl. Amer. Med. Assoc. 15 Oct. 1352/1 Evidences of atrial fibrillation cannot be obtained with venous pulse, as the fibrillating auricle does not give any wave on it.

1980 D. R. Maloff & P. K. Levinson Issues Controlled Substance Use 117 In this study 10 patients suffering from atrial fibrillations were given digitoxin.

2008 Daily Tel. 4 Sept. 1/5 The largest trial in patients with atrial fibrillation (AF) showed that the drug Multaq reduced the risk of stroke by more than a third.

atrial natriuretic factor n. Physiology = atrial natriuretic peptide n.; abbreviated ANF.

ΚΠ

1981 Canad. Jrnl. Physiol. & Pharmacol. 59 1279/1 Our present results suggest that the atrial natriuretic factor may be such an ‘endogenous diuretic’.

2008 M. S. Ebadi Desk Ref. Clin. Pharmacol. (ed. 2) 93/2 Atrial extracts possess both vasodilatory and natriuretic activity that is mediated by atrial natriuretic factor.

atrial natriuretic peptide n. Physiology a peptide hormone secreted by atrial muscle cells which causes increased excretion of sodium and water by the kidneys and has a variety of other effects on the cardiovascular system, generally tending to reduce blood pressure; abbreviated ANP.

ΚΠ

1984 Biochem. & Biophysical Res. Communications 119 527 The contribution of the ring structure of the atrial natriuretic peptide to its natriuretic activity was examined.

2004 M. Moretti et al. in N. M. Siafakas et al. Acute Exacerbations Chronic Obstructive Pulmonary Dis. xvi. 271 The high levels of atrial natriuretic peptide may be the reason that not all patients who present with hypoxic-hypercapnic respiratory failure develop peripheral edema.
