摘　　要：对254名临床上无器质性心脏病的招飞体检申请者进行超声心动图研究，以建立小心脏综合征的超声心动图诊断标准。按标准方法，用ALOKASSD－260超声诊断仪检查。测量计算左室舒张末期内径（EDD）、舒张末期容积（EDV）、心肌质量（LVM）、心搏量（SV）、短轴缩短率（FS）和射血分数（EF），以x－2s的方法确定左室功能各参数的下限，分别为4.1cm（EDD）、60．91ml（EDV）、110．9g（LVM）、32．2ml（SV）、0．26（FS）和0．52（EF）。EDD、EDV、LVM有一项以上达不到上述下限者，属于小心脏。小心脏合并左室功能下降者诊断为小心脏综合征，建议后者招飞体检不合格。The purpose of this study was to establish echocardiographic criteria of small heart syndrome for selection of student pilot. Standard M-mode and two-dimensional echocardiograms weretaken in 254 student pilot applicants without organic heart disease, using ALOKA SSD-260. The following anatomical and functional parameters of left ventricle(LV) were measured and calculated accordingtostandard procedures of echocardiography: end-diastolic internal dimension (EDD), end-diastolicvolume (EDV), left ventricular mass (LVM), stroke volume (SV), fractional shortening (FS), and ejectionfraction (EF). The demarcation was set at x- 2s of these parameters, 4. 1 cm (EDD), 60. 9 ml (EDV),110. 9 g (LVM), 32. 2 ml (SV), 0. 26 (FS), and 0. 52 (EF), respectively. Those with one or moreanatomical parameters (EDD、EDV、LVM) lower than the demarcation set above were referred to smallheart. Subjects with small heart accompanied by one or more lower functional parameters (SV、FS、EF)were diagnosed as small heart syndrome. Using this criteria, the prevalence rate of small heart syndrome was 1. 2% in this study. It is suggested that small heart syndrome is disqualifying for studentpilots.
