LV End-Systolic Volume Unit Converter

Left ventricular end-systolic volume (LVESV) is the amount of blood remaining in the left ventricle at the end of each heartbeat, after the heart has finished contracting and pumping blood out to the body.

A healthy heart empties most of its blood with each contraction, leaving only a small residual volume. When the heart muscle weakens or the chamber enlarges, more blood is left behind, resulting in a higher LVESV.

LVESV is used alongside left ventricular end-diastolic volume (LVEDV) to calculate ejection fraction, one of the most important measures of heart function. It is often indexed to body surface area (LVESVI) to allow comparison across different body sizes.

LVESV is not a substance produced by the body. It is a measurement of the residual blood volume in the left ventricle of the heart at the end of systole (contraction), determined by the strength of cardiac muscle contraction and the resistance the heart pumps against (afterload).
