| ventricular inhibited pulse generator | A generator which suppresses its output in response to natural ventricular activity but which, in the absence of such activity, functions as an asynchronous pulse generator. Synonym: demand pulse generator, standby pulse generator. (05 Mar 2000) |
|---|---|
| ventricular layer | An inner epithelial layer of cells bordering the lumen of the embryonic neural tube and brain, formed during the latter's stratification, and persisting in modified form throughout life. Synonym: ependymal zone, ventricular layer. (05 Mar 2000) |
| ventricular ligament | <anatomy> The thin fibrous layer that lies in the ventricular fold of the larynx. Synonym: ligamentum vestibulare, ligamentum ventriculare, ventricular ligament. (05 Mar 2000) |
| ventricular loop | The portion of the early-somite embryonic cardiac tube that evolves into the ventricle and bulbus cordis. Synonym: ventricular loop. (05 Mar 2000) |
| ventricular outflow obstruction | Occlusion of the ventricular outflow or inflow tract on either side of the heart. It may result from a congenital defect or predisposing heart disease, or as a complication of surgery or tumours of the heart or its vessels. (12 Dec 1998) |
| ventricular plateau | A level diastolic portion of the intraventricular blood pressure curve, representing graphically an equilibrium or final state of filling. (05 Mar 2000) |
| ventricular ponderance | A semiobsolete electrocardiographic term suggesting that one ventricle is either larger or thicker than the other. (05 Mar 2000) |
| ventricular preexcitation | See: Wolff-Parkinson-White syndrome. (05 Mar 2000) |
| ventricular premature complexes | Premature contractions of the ventricle, the most common of all arrhythmias. In the absence of heart disease, they are not of great clinical significance, but in patients with coronary disease, they represent a constant danger of ventricular tachycardia or fibrillation and sudden death. The longer-term prognosis for asymptomatic, healthy subjects with frequent and complex ectopy is similar to that for the healthy united states population. (12 Dec 1998) |
| ventricular pressure | The pressure within a cardiac ventricle. Ventricular pressure waveforms can be measured in the beating heart by catheterization or estimated using imaging techniques (e.g., doppler echocardiography). The information is useful in evaluating the function of the myocardium, cardiac valves, and pericardium, particularly with simultaneous measurement of other (e.g., aortic or atrial) pressures. (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) |
| ventricular septal defect | <cardiology, embryology> A congenital heart defect where an abnormal opening exists in the ventricular septum. Blood flows from the higher pressure left ventricle (through the defect) into the right ventricle. (12 Jan 1998) |
| ventricular septal rupture | Rupture of the intraventricular septum of the heart, usually secondary to myocardial infarction. (12 Dec 1998) |
| ventricular septum | <anatomy> A muscular wall which separates the left ventricle from the right ventricle. The heart's conduction system travels through the ventricular septum. Damage to the ventricular septum (for example heart attack) can result in cardiac conduction abnormalities. (12 Jan 1998) |
| ventricular synchronous 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 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.

| 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.

| ventriculogram |
x-ray motion pictures of the ventricles showing contraction of the heart muscle.
