| ventricular flutter | A form of rapid ventricular tachycardia in which the electrocardiographic complexes assume a regular undulating pattern without distinct QRS and T waves. (05 Mar 2000) |
|---|---|
| ventricular fold | One of the pair of folds of mucous membrane stretching across the laryngeal cavity from the angle of the thyroid cartilage to the arytenoid cartilage; they enclose a space called the rima vestibuli or false glottis. Synonym: plica vestibularis, false vocal cord, plica ventricularis, ventricular band of larynx, ventricular fold. (05 Mar 2000) |
| ventricular function | The haemodynamic and electrophysiological action of the ventricles. (12 Dec 1998) |
| ventricular function, left | The haemodynamic and electrophysiological action of the left ventricle. Its measurement is an important aspect of the clinical evaluation of patients with heart disease to determine the effects of the disease on cardiac performance. (12 Dec 1998) |
| ventricular function, right | The haemodynamic and electrophysiological action of the right ventricle. (12 Dec 1998) |
| ventricular gradient | The algebraic sum of (i.e., the net electrical difference between) the area enclosed within the QRS complex and that within the T wave in the electrocardiogram. (05 Mar 2000) |
| 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 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.
