【】：Objective: Preliminary build left ventricular volume and contraction and the parameters of diastolic synchronism normal range Methods： Analysis 120 cases of normal adult male parameters of left ventricular volume(EF、EDV、ESV、SV、ESSI、EDSI) and Left ventricular systolic and diastolic pushed period of volume change synchronization parameters(SDI、DDI、DISPES、DISPED、MES、MED、PreContr、PostContr、PreRlax、PostRlax) with instantaneous full-volume imaging Result: Acquire normal adult men left ventricular volume parameter and left ventricular contraction and diastolic segmental volume change synchronization parameters 95% normal reference range,it shows significant positive correlation between EDV ESV SV MES and surface area(Scorrelation coefficient of 0.488 0.371 0.432 0.259 p<0.05) . Conclusion Instantaneous full-volume imaging technology plays an important role in the normal range of the parameters of measurement in left ventricular volume and systolic and diastolic synchronism ,and normal reference range of various parameters will make IFI technology fly highly in the application of ultrasonic clinical research .
