M Measure

  • LVIDd : Left ventricular internal diameter end diastole
  • LVIDs: Left ventricular internal diameter end systole
  • EDV: End diastolic volume, amount of blood in the ventricle during diastole
  • ESV: End systolic volume, amount of blood in ventricle after systole
  • EDVIndex: End-diastolic volume index, referred to as EDV corrected for BSA
  • ESVindex: End- systolic volume index
  • SV: Stroke volume, volume of blood pumped from the heart in one cycle of diastole and systole, is affected by Preload, contractility and Afterload
  • CO: Cardiac output, quantity of blood pumped per minute through the aorta and into the peripheral circulation, is proportional to (Arterial pressure / Total peripheral resistance)
  • EF: Ejection fraction, reflects the percentage of blood ejected from the ventricle
  • FS: Fractional shortening
