| ventricular complex | The continuous QRST waves of each beat in the electrocardiogram. (05 Mar 2000) |
|---|---|
| ventricular conduction | Conduction of the cardiac impulse through the ventricular myocardium, represented by the QRS complex in the electrocardiogram. H-R conduction time is from the onset of the first high frequency component of the His bundle electrogram to the onset of the QRS complex of the surface electrocardiogram (normally 43 ± 12 msec); H-V conduction time is from the onset of the first high frequency component of the His bundle electrogram to the onset of the ventricular electrogram (normally approximates the H-R interval but may be a little shorter). Synonym: ventricular conduction. (05 Mar 2000) |
| ventricular diastole | Period of relaxation and repolarization of the ventricular muscle. (05 Mar 2000) |
| ventricular diverticulum | A congenital outpouching of the right or left ventricle. (05 Mar 2000) |
| ventricular dysfunction | A condition in which the ventricles of the heart exhibit a decreased functionality. (12 Dec 1998) |
| ventricular dysfunction, left | A condition in which the left ventricle of the heart exhibits a decreased functionality. This decreased function could lead to congestive heart failure or myocardial infarction, among other cardiovascular diseases. Diagnostic measurements that indicate this condition include a diminished ejection fraction and a depressed level of motility of the left ventricular wall. (12 Dec 1998) |
| ventricular dysfunction, right | A condition in which the right ventricle of the heart exhibits a decreased functionality. This decreased function could lead to congestive heart failure or myocardial infarction, among other cardiovascular diseases. Diagnostic measurements that indicate this condition include a diminished ejection fraction and a depressed level of motility of the right ventricular wall. (12 Dec 1998) |
| ventricular extrasystole | A premature contraction of the ventricle. Synonym: infranodal extrasystole. (05 Mar 2000) |
| ventricular fibrillation | <cardiology> A disorganised chaotic contraction of the ventricle that fails to effectively eject blood from the ventricle. During ventricular fibrillation the patient is unconscious and will die if emergency intervention is not undertaken (defibrillation). (12 Jan 1998) |
| ventricular filling pressure | The pressure in the ventricle as it fills with blood, ordinarily equivalent to the mean atrial pressure when there is no A-V valvular gradient. Atrial pressure can be used in place of transmural pressure because pericardial pressure usually varies between -2 and +2 mm Hg and hence is negligible. During cardiac tamponade, pericardial and atrial pressures equilibrate so that transmural pressure is zero and the high atrial presures cannot be "filling" pressures. (05 Mar 2000) |
| ventricular fluid | The portion of the cerebrospinal fluid that is contained in the ventricles of the brain. (05 Mar 2000) |
| 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) |
