摘　　要：本文67例左室电影造影和冠脉造影病例按冠脉造影的结果分组,采用长轴中点法和重心法将左室分别分成6、12、24、36、48个节段,利用节段功能指标(即面积和半径缩短率为反映冠脉病变的参数),通过Bayes判别分析回测分类与冠造分类的符合率,比较了每种分段方法测定结果的差异。结果表明左室节段功能测定分段数不应少于36,而在36～48个节段间较为合适。Sixty seven cases of cineangiocardiography weregrouped, according to the result of coronary arteriography. Left ventricular silhouettes were divided into6, 12, 24, 36 and 48 segments with the midpoint oflong axis method and the center of mass method. Regional left ventricular function indices (area shortening rate and radius shortening rate) were used as parameters to reflect coronary artery lesion. The assessment results with different segments were compared by the coincidence rate of the selftest classification of Bayes dtscriminant analysis and the classification of coronary arteriography. We conclude that the appropriate number of segment in assessing regional left ventricular function should be between 36 and 48.
