Blood vessels that transport blood from all parts of the body back to the heart.
a rarely-used test to diagnose deep vein thrombosis and chronic vein disease; this test uses a special dye injected into the blood to produce X-ray images of the veins and blood flow through them; also called phlebography
|venous pressure measurements||
a test that measures the blood pressure in a vein using a needle inserted into the top of the foot or the thigh; used to provide information about the location and severity of vein disease
|venous thromboembolism (VTE)||
a general term for blood clots that formed in a vein and may travel through the bloodstream; VTE includes deep vein thrombosis (DVT) and pulmonary embolism (PE)
A blood clot in a vein. Clots that are deep in the body are the most dangerous, because of their tendency to migrate and block other vessels. See Deep-vein thrombosis.
One of the two main pumping chambers of the heart. Both ventricles contract forcefully; the right ventricle pushes blood into the lungs to pick up oxygen, and the left one pumps oxygen-rich blood out to the body.
a serious type of abnormal heart rhythm in which the main pumping chambers of the heart beat in a disorganized manner (or quiver); if it is not corrected it can caused sudden cardiac death; to prevent this, patients who are at risk may need to have an ICD implanted to detect and stop the abnormal rhythm
thickening of the walls of the pumping chambers of the heart that happens in some women with blood filling problems (diastolic heart failure)
|ventricular septal defect (VSD)||
a type of congenital heart defect in which there is a hole in the heart muscle wall that separates the left ventricle from the right ventricle; this allows oxygen-rich blood to flow from the left ventricle into the right ventricle instead of out to the rest of the body; a large VSD can cause the heart to work too hard to pump blood and lead to heart failure
a serious type of abnormal heart rhythm in which the main pumping chambers of the heart beat too fast: if this goes on for a long time (sustained ventricular tachycardia) it can result in sudden cardiac death; to prevent this, patients who are at risk may need to have an ICD implanted to detect and stop the abnormal rhythm
|Voice output communication aids (VOCA)||
technology used to assist stroke survivors with communication problems
