| 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) |
| hypertrophy, right ventricular | Enlargement of the right ventricle of the heart. This increase in ventricular mass is often attributed to pulmonary hypertension and is a contributor to cardiovascular morbidity and mortality. (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) |
| abdominal aortic aneurysm | <surgery> A distended and weakened area in the wall of the abdominal aorta, more common in those who suffer from atherosclerosis. Symptoms include sudden, severe abdominal pain with radiation to the back. (27 Sep 1997) |
| abdominal aortic coarctation | <radiology> 2% of all coarctations, (most common site is thoracic: just distal to origin of L SCA), may be isolated congenital anomaly, associated with: thoracic aortic coarctation, idiopathic hypercalcaemia syndrome, rubella syndrome (ToRCHS), Takayasu arteritis, neurofibromatosis, radiation therapy, fibromuscular disease (12 Dec 1998) |
| abdominal aortic plexus | <anatomy, neurology> An autonomic plexus surrounding the abdominal aorta, directly continuous with the thoracic aortic plexus above and continued inferior to the bifurcation of the aorta as the superior hypogastric plexus. Synonym: plexus aorticus abdominalis. (05 Mar 2000) |
