Comparison of systolic and diastolic kinetic energy per LV stroke volume in different categories of LV impairment. KE = kinetic energy, nEF = normal ejection fraction, pEF = preserved ejection fraction, Mild rEF = mildly reduced ejection fraction, Moderate rEF = moderately reduced EF, Severe rEF = severely reduced EF and SV = stroke volume
