心室測量

• IVSd: Interventricular septum in diastole 舒張期室間隔厚度
• LVIDd : Left ventricular internal diameter end diastole 左心室舒張末期內徑
• LVPWd: Left ventricular Posterior wall in diastole 左心室舒張期後壁厚度
• IVSs: Interventricular septum in systole 收縮期室間隔厚度
• LVIDs: Left ventricular internal diameter end systole 左心室收縮末期內徑
• LVPWs: Left ventricular posterior wall in systole 左心室收縮期後壁厚度
• BSA: Body Surface Area 體表面積= (身高 * 體重 / 3600)^½
• EDV(ml): End diastolic volume, amount of blood in the ventricle during diastole 心舒末期容積 = (7 * LVIDd(cm)³) / (2.4 + LVIDd(cm))
• ESV(ml): End systolic volume, amount of blood in ventricle after systole 心縮末期容積
  = (7 * LVIDs(cm)³) / (2.4 + LVIDs(cm))
• EDV Index: End-diastolic volume index, referred to as EDV corrected for BSA 心舒末期容積指數
  • = EDV / BSA
• ESV Index: End- systolic volume index 心縮末期容積指數
  • = ESV / 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 心搏量
  • = 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) 心輸出量
  • = SV * HR
• EF: Ejection fraction, reflects the percentage of blood ejected from the ventricle射出率
  • = SV / EDV * 100%
• FS: Fractional shortening 收縮分率
  • = (LVIDd – LVIDs) / LVIDd * 100%
