| ventricular systole | Contraction of the ventricles. (05 Mar 2000) |
|---|---|
| ventricular tachycardia | <cardiology> Abnormal accelerated ventricular rhythm with a usual rate of 150-200 beats per minute. Because ventricular tachycardia originates in the ventricle, it appears as a wide complex rhythm on ECG. A potentially unstable rhythm that may result in fainting, low blood pressure, shock or sudden death. Ventricular tachycardia has the potential of degrading to the more serious ventricular fibrillation. Ventricular tachycardia is a common and often, lethal complication of acute myocardial infarction (heart attack). Origin: Gr. Kardia = heart (12 Jan 1998) |
| ventricular triggered pulse generator | A pulse which delivers its output synchronously with naturally occurring ventricular activity but which, in the absence of such activity, functions as an asynchronous pulse generator. Synonym: ventricular triggered pulse generator. (05 Mar 2000) |
| ventricular trigone | A triangular prominence of the floor of the lateral ventricle at the transition between occipital and temporal horn, continuous rostrally with the collateral eminence and, like the latter, caused by the deep penetration of the collateral sulcus from the ventral surface of the temporal lobe. Synonym: trigonum collaterale, trigone of lateral ventricle, trigonum ventriculi, ventricular trigone. (05 Mar 2000) |
| ventricularis | Synonym: ventricular. Synonym: thyroepiglottic muscle. Origin: Mod. L. Fr. L. Ventriculus (05 Mar 2000) |
| ventricularization | Transformation of an atrial phenomenon to simulate a ventricular one, especially of the atrial (or venous) pulse tracing in tricuspid regurgitation. (05 Mar 2000) |
| ventriculite | <paleontology> Any one of numerous species of siliceous fossil sponges belonging to Ventriculites and allied genera, characteristic of the Cretaceous period. Many of them were shaped like vases, others like mushrooms. They belong to the hexactinellids, and are allied to the Venus's basket of modern seas. See: Ventriculus.

| ventriculitis | Inflammation of the ventricles of the brain. Origin: ventricle + G. -itis, inflammation (05 Mar 2000) |
| ventriculo- | A ventricle. Origin: L. Ventriculus (05 Mar 2000) |
| ventriculoatrial | Relating to both ventricles and atria, especially to the sequential passage of conduction in the retrograde direction from ventricle to atrium. (05 Mar 2000) |
| ventriculoatrial conduction | Conduction backward from the ventricles or from the A-V node into and through the atria. Synonym: retroconduction, ventriculoatrial conduction, V-A conduction. (05 Mar 2000) |
| ventriculocisternostomy | An artificial opening between the ventricles of the brain and the cisterna magna. See: shunt. Origin: ventriculo-+ L. Cisterna, cistern, + G. Stoma, mouth (05 Mar 2000) |
| ventriculography | 1. Radiograph demonstration of the cerebral ventricles by direct injection of air or contrast medium; developed and described by Dandy in 1918. Compare: pneumoencephalography. 2. Demonstration of the contractility of the cardiac ventricles by recording serially the distribution of intravenously injected radionuclide or that of radiographic contrast medium injected through an intracardiac catheter. 3. Visualization by roentgenography of a cardiac ventricle by injection of radiopaque contrast material. Origin: ventriculo-+ G. Graphe, a writing (05 Mar 2000) |
| ventriculography, first-pass | Radionuclide ventriculography where a bolus of radionuclide is injected and data are recorded from one pass through the heart ventricle. Left and right ventricular function can be analyzed independently during this technique. First-pass ventriculography is preferred over gated blood pool imaging for assessing right ventricular function. (12 Dec 1998) |
| ventriculomastoidostomy | Operation for the establishment of a communication between the lateral cerebral ventricle and the mastoid antrum by means of a polythene tube for the relief of hydrocephalus. See: shunt. Origin: ventriculo-+ mastoid, + G. Stoma, mouth (05 Mar 2000) |

| ventilation rate |
The rate at which indoor air enters and leaves a building. Expressed as the number of changes of outdoor air per unit of time (air changes per hour (ACH), or the rate at which a volume of outdoor air enters in cubic feet per minute (CFM).
