| circadian rhythm | The regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs and stimuli, hormone secretion, sleeping, feeding, etc. This rhythm seems to be set by a 'biological clock' which seems to be set by recurring daylight and darkness. (12 Dec 1998) |

| circadian | Relating to biologic variations or rhythms with a cycle of about 24 hours. Compare: infradian, ultradian. Origin: L. Circa, about, + dies, day (05 Mar 2000) |
|---|---|
| circadian clock | <physiology> A biological timing mechanism that controls cell synchronisation (a entire population of cells divides simultaneously). (09 Oct 1997) |
| accelerated idioventricular rhythm | A transient and intermittent type of arrhythmia with episodes lasting from a few seconds to a minute which usually occurs in patients with acute myocardial infarction or with digitalis toxicity. Suppressive therapy is rarely necessary because the ventricular rate is generally less than 100 beats per minute. (12 Dec 1998) |
| agonal rhythm | An idioventricular rhythm, characterised by unusually wide and bizarre ventricular complexes, often seen in moribund patients. (05 Mar 2000) |
| alpha rhythm | Brain waves in the encephalogram which have a frequency of 8 to 13 per second. They are typical of the normal person awake and in a quiet resting state, and occur principally in the occipital region. (12 Dec 1998) |
| 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) |
| A-V 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) |
| basic electrical rhythm | A slow wave of depolarisation of smooth muscle from the fundus to the pylorus that coordinates gastric peristalsis and emptying. (05 Mar 2000) |
| Berger rhythm | Brain waves in the encephalogram which have a frequency of 8 to 13 per second. They are typical of the normal person awake and in a quiet resting state, and occur principally in the occipital region. (12 Dec 1998) |
| beta rhythm | <neurology> Brain waves in the electroencephalogram which have a frequency of 18 to 30 per second. They are typical during periods of intense activity of the nervous system, and occur principally in the parietal and frontal regions. (12 Dec 1998) |
| bigeminal rhythm | That cardiac rhythm when each beat of the dominant rhythm (sinus or other) is followed by a premature beat, with the result that the heartbeats occur in pairs (bigeminy). Synonym: coupled rhythm. (05 Mar 2000) |
| cantering rhythm | A triple cadence to the heart sounds; due to an abnormal third or fourth heart sound being heard in addition to the first and second sounds, and usually indicative of serious disease. Synonym: bruit de galop, cantering rhythm, gallop rhythm, Traube's bruit. (05 Mar 2000) |
| gallop rhythm | Heart rhythm like the gallop of a horse. (12 Dec 1998) |
| ventricular rhythm | A slow independent ventricular rhythm under control of a ventricular centre (which is, by definition, ectopic). Synonym: ventricular rhythm. (05 Mar 2000) |
| reciprocal rhythm | A cardiac arrhythmia in which the impulse arising in the A-V junction descends to and activates the ventricles on one intrajunctional pathway and simultaneously ascends toward the atria in parallel pathways; before reaching the atria, however, the impulse is reflected downward and again activates the ventricles, producing an echo or reciprocal beat; recognised in the electrocardiogram by the presence of an inverted P wave in lead aVF and usually II sandwiched between two ventricular complexes aberrantly, both of which may be normal or one of which may be conducted.

| circadian rhythm sleep disorder |
[DSM-IV] a sleep disorder of the dyssomnia group, consisting of a lack of synchrony between the schedule of sleeping and waking required by the external environment and that of a person's own circadian rhythm. It usually has an environmental cause such as rotating shift work or long-distance air travel, although some individuals simply have natural circadian rhythms sharply different from the predominant one of their society.
