| 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) |

| right ventricular failure | An weakening of the right ventricle that results in the back up of blood in the venous system, liver, gastrointestinal tract and extremities. The causes of this condition include left-sided congestive heart failure, emphysema, valvular heart disease, cardiomyopathy, anaemia, hyperthyroidism, cor pulmonale and congenital heart disease. Risk factors include diabetes, alcoholism, obesity and smoking. Symptoms include swelling of the feet and ankles, nocturia, increased distention of neck veins, fatigue, weakness and fainting, Ascites, arrhythmias and pleural effusions are complications of right ventricular failure. (27 Sep 1997) |
| right ventricular hypoplasia | A congenital or acquired condition in which there is thinning of the right ventricular myocardium. Synonym: right ventricular hypoplasia. (05 Mar 2000) |
| right ventricular volume overload | <radiology> Atrial septal defect, partial/total APVR, tricuspid insufficiency, pulmonary insufficiency, congenital/aquired absence of pericardium, Ebstein anomaly (not truly RV) (12 Dec 1998) |
| postinfarction ventricular septal defect | A defect developed in the ventricular septum resulting from rupture of an acute myocardial infarction. (05 Mar 2000) |
| premature ventricular contraction | <cardiology> A cardiac arrhythmia which originates from within the ventricles. Isolated ventricular contractions are referred to as premature ventricular contractions. Frequent premature ventricular contractions can be potentially unstable and can degrade to a more serious rhythm or cardiac arrest. Acronym: PVC (31 Dec 1997) |
| premature ventricular contractions | Contractions of the lower chambers of the heart, the ventricles, which occur earlier than usual, because of abnormal electrical activity of the ventricles. The premature contraction is followed by a pause, as the heart electrical system resets itself and the contraction following the pause is usually more forceful than normal. These more forceful contractions are frequently perceived as palpitations. (12 Dec 1998) |
| heart septal defects, ventricular | Congenital defects in the septum between the cardiac ventricles, most often due to failure of the bulbar septum to completely close the interventricular foramen. (12 Dec 1998) |
| septal defect, ventricular | A hole in the interventricular septum, the wall between the ventricles, the lower chambers of the heart. Commonly called a vsd. Vsds are a common class of heart deformity that is present at birth (congenital cardiac malformation). (12 Dec 1998) |
| septum, ventricular | The wall between the two lower chambers (the right and left ventricles) of the heart. (12 Dec 1998) |
| defect, ventricular septal | Hole in the interventricular septum, the wall between the ventricles (lower chambers of the heart). Commonly called a VSD. VSDs are a common class of heart deformity present at birth (congenital cardiac malformation). (17 Dec 1998) |
| inferior ventricular vein | Vein draining the deep white matter of the superior and lateral portions of the temporal lobe; it begins in the body of the lateral ventricle and exits from the choroid fissure of the inferior horn where it joins the basal vein. Synonym: inferior ventricular vein. (05 Mar 2000) |
| tachycardia, ventricular | An abnormal heart rhythm that is rapid, regular and originates from an area of the ventricle, the lower chamber of the heart. Ventricular tachycardias are life threatening arrhythmias most commonly associated with heart attacks or scarring of the heart muscle from previous heart attack. (12 Dec 1998) |
| escape ventricular contraction | An escape beat arising in the ventricle. (05 Mar 2000) |
| fibrillation, ventricular | An abnormal irregular heart rhythm whereby there are very rapid uncoordinated fluttering contractions of the lower chambers (ventricles) of the heart. Venticular fibrillation disrupts the synchrony between the heartbeat and the pulse beat. Ventricular fibrillation is commonly associated with heart attacks or scarring of the heart muscle from previous heart attack. Ventricular fibrillation is life threatening. (12 Dec 1998) |
