M mode measurement

• Ventricle 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
• EDV Index: End-diastolic volume index, referred to as EDV corrected for BSA
  = EDV / BSA
• ESV Index: End- systolic volume index
  = EDV / BSA
• SV: Stroke volume, volume of blood pumped from the heart in one cycle of diastole and systole, is affected by
• Preload, contractility and Afterload
  = EDV – ESV
• 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)
  = SV * HR
• EF: Ejection fraction, reflects the percentage of blood ejected from the ventricle
  = SV / EDV * 100%
• FS: Fractional shortening
  = (LVIDd – LVIDs) / LVIDd * 100%%

Cardiac measurement in B mode

• BSA: Body Surface Area
  = (Height * Weight / 3600)^½
• SV (ml): Stroke volume
  = EDV – ESV
• SI (ml/m²): Stroke volume index
  = SV / BSA
• CO (l/min): Cardiac output
  = SV * HR / 1000
• CI (l/m/m²): Cardiac Index
  = CO / BSA
• EF (%): Ejection fraction
  = SV / EDV * 100%
