摘　　要：目的应用单心动周期全容积成像(IFI)技术初步建立健康成年男性左室容积及收缩与舒张同步性各参数的正常值范围。方法应用IFI技术测量并分析120例健康成年男性左室容积参数(射血分数、舒张末容积、收缩末容积、每搏量、收缩末期球形指数、舒张末期球形指数)和左室收缩及舒张期节段容积变化同步性参数(包括收缩失同步性指数、舒张失同步性指数、收缩末离散度、舒张末离散度、平均收缩末时间、平均舒张末时间、收缩前时间容积、收缩后时间容积、舒张前时间容积及舒张后时间容积)。结果成功获得健康成年男性左室容积参数和左室收缩与舒张期各节段容积变化同步性参数95%正常参考值范围,舒张末容积、收缩末容积、每搏量及平均收缩末时间与体表面积之间呈正相关(r=0.488、0.371、0.432、0.259,均P<0.05)。结论应用IFI技术成功获取健康成人男性左室收缩容积及收缩与舒张期同步性各参数的正常值范围,可为IFI技术在超声临床研究中的应用提供相应标准。Objective To preliminarily build normal range of left ventricular volume and systolic and diastolic synchronism by instantaneous full-volume imaging.Methods A totale of 120 normal male adults 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,Pre Contr,Post Contr,Pre Relax,Post Relax）were measured and analyzed by instantaneous full-volume imaging Results Left ventricular volume parameter,left ventricular systolic and diastolic segmental volume change synchronization parameters of normal male adults were successfully obtained within 95% normal reference range,it showed significant positive correlation between EDV,ESV,SV,MES and surface area（r=0.488,0.371,0.432,0.259,all P0.05）.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.
