SV stands for stroke volume, which refers to the amount of blood ejected by the heart with each contraction. In the context of cardiovascular health, SV is an important measure as it helps determine the efficiency of the heart in pumping blood throughout the body. A higher SV is typically associated with better cardiovascular fitness, while a lower SV may indicate issues with heart function or circulation. Regular exercise and a healthy lifestyle can help improve SV and overall cardiovascular health.
