There are multiple definitions:
ventricular pacing plus sensing, inhibited above a preset HR(English)
velocity vector imaging(English)
- a technique to estimate strain and strain rate, i.e. software for analyzing gray scale images

ventricular-vascular coupling index(English)
- also called ventriculo-arterial coupling (Ea/Ees), measures how well the heart's left ventricle works with the blood vessels. It is calculated as the ratio of effective arterial elastance (Ea), representing arterial load) to end-systolic elastance (Ees), representing ventricular contractility. A balanced ratio near 1.0 shows optimal cardiovascular efficiency
