摘　　要：用长轴中点法将左室分为３６节段，以面积缩小率为节段功能参数，对６７例Ｘ线左室电影造影图像进行定量左室节段功能测定。冠心病组节段功能障碍总检出率为８７．５％（４２／４８），心绞痛亚组为７９．３％（２３／２９），心肌梗塞亚组为１００％（１９／１９），两亚组之间有显著差异（Ｐ＜０．０５）。冠脉病变的部位不同，出现功能障碍的节段也不同。１９例心肌梗塞病人节段功能减弱部位，心电图上相应导联均有病理性Ｑ波。结果表明：节段功能障碍的检出与冠心病临床轻重有关，Ｘ线电影造影左室节段功能测定对心肌梗塞有定位诊断价值，是诊断冠心病的可靠方法之一。Regional left ventricular function was quantitatively.assessed by using″he mid-point of long axis″ method. The left ventricle was divided into 36 segments and the area reduction rate in cineangiocardiography was the functional parameter which was available in 67 cases. The re- sults showed that detectability of regional left ventricular dysfunction was 87.5%(42/48 ) in coro-nary artery disease group, 79.3%(23/29) in angina pectoris subgroup and 100%(19/19) in myocar-dial infarction subgroup,significant difference existed between the two subgroups(P< 0. 05); each coronary artery stenosis had its specific dysfunction segment. There was pathologic Q wave in the leads of electrocardiologram corresponding to the segment with dysfunction in all of 19 cases of my-ocardial infarction. It was concluded that the detectability rate is related to the clinical manifestations of coronary artery disease, It is a reliable method for diagnosis of coronary artery disease,and locali-zation of mvocardial infarction.
