DVI Medical Abbreviations

"DVI" is a common medical acronym predominantly used to define terms related to vascular conditions, and the techniques used to identify these conditions. If you or a loved one are receiving treatment for an illness, or if you are performing independent research, ask your doctor what DVI stands for as it relates to your case. Definitions provided here for DVI should not be used as the starting point for attempting to diagnose an illness.

DVI, AV Sequential (Pacemaker)

• "DVI, AV sequential" is the most common way this is written. The pacemaker provides stimulus to the heart at specific predetermined intervals to help control the speed at which the heart beats.

Deep Venous Insufficiency

• Deep venous insufficiency is the development of varicose veins (often in the ankles and lower legs) or stasis ulcers of the veins (ulcers are holes that occur due to a loss of circulation in the deep veins). Deep venous insufficiency can be caused by problems with the valves that direct blood from the deep veins back to the heart, or by deep vein thrombosis (in which blockages are present in the deep veins).

Diastolic Velocity Integral

• An increase in diastolic velocity integral (as measured through medical testing) may indicate various disorders related to the heart, including mitral regurgitation (which occurs when the mitral valve does not close properly when the heart is pumping out blood). Mitral regurgitation can lead to severe abnormalities of the left atrium and the left ventricle.

Digital Vascular Imaging

• In digital vascular imaging, digital techniques are used to edit or improve images of the vascular system (veins, arteries and so forth) that are obtained by physicians. These images are used to diagnose conditions such as arteriosclerosis, in which deposits adhere and collect along the walls of arteries, potentially leading to artery blockage and potential heart attack when left untreated.

Doppler Velocity Imaging

• Known by a wide variety of other names as well (such as "pulsed Doppler tissue imaging"), Doppler velocity imaging is generally used to evaluate the functioning of the myocardium (the middle layer of the heart wall; it is composed of muscle and contracts with the heartbeat).
