| 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) |
| ventriculonector | Synonym: atrioventricular bundle. Origin: ventriculo-+ L. Necto, to join (05 Mar 2000) |
| ventriculoperitoneal shunt | <procedure> A surgical procedure to insert a communicating catheter to relieve intracranial pressure caused by hydrocephalus. In this procedure the cerebrospinal fluid is shunted from the ventricles of the brain into the peritoneal cavity via a surgically implanted tube. (27 Sep 1997) |
| ventriculophasic | Influenced by ventricular contraction; applied to the atrial rhythm when this is modified by ventricular contraction; in ventriculophasic sinus arrhythmia in complete A-V block the sinus impulse immediately following a ventricular contraction usually appears sooner than expected. (05 Mar 2000) |
| ventriculoplasty | Any surgical procedure to repair a defect of one of the ventricles of the heart. Origin: ventriculo-+ G. Plastos, formed (05 Mar 2000) |
| ventriculopuncture | Insertion of a needle into a ventricle. (05 Mar 2000) |
| ventriculoradial dysplasia | A congenital syndrome consisting of a ventricular septal defect with associated absence of thumb or radius. (05 Mar 2000) |
| ventricle |
a partition, sac or cavity (eg, the fluid-filled spaces in the center of the brain, the chambers of the heart).

| ventricular fibrillation |
Ventricular fibrillation is an especially dangerous form of arrhythmia in which the contractions of the ventricles are rapid, unsynchronized, and uncoordinated, so that the heart pumps very little or no blood.

A normal cavity, as of the brain or heart.

|
| ventricular fibrillation |
An erratic, disorganized firing of impulses from the ventricles. The ventricles quiver and are unable to contract or pump blood to the body. This is a medical emergency that must be treated with cardiopulmonary resuscitation (CPR) and defibrillation as soon as possible.

|
| ventricular tachycardia |
A rapid life-threatening rhythm originating from the lower chambers of the heart. The rapid rate prevents the heart from filling adequately with blood, and less blood is able to pump through the body.
