| 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.

| 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 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) |
| 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.

| ventricle |
L. ventriculus, from venter, belly, chamber, cavity. Ventricles of the brain were so-named because it was at one time fashionable to name parts of the brain for other parts of the body that they resembled.
