摘　　要：目的 :探讨应用多普勒技术测定左心室射血力 (LVF)及校正的Q V峰值间期 (QVc)两种新方法评价左心室收缩功能。　　方法 :运用上述两种方法对 78例冠心病患者 (冠心病组 )及 5 0例正常人 (对照组 )进行测定 ,并与他们的二维超声法获取的左心室射血分数 (LVEF)相比较。　　结果 :LVF、Q V峰值间期、LVEF值在对照组与冠心病组间均存在着显著差异 (P均 <0 0 5 )。在对照组及冠心病组 ,LVF与LVEF均相关良好 (r分别为 0 8415 ,0 82 5 1,P均 <0 0 5 ) ,Q V峰值间期与LVEF也均相关良好 (r分别为-0 7844 ,-0 80 13 ,P均 <0 0 5 )。　　结论 :LVF、Q V峰值间期是评价左心室收缩功能较好的指标。Objective: To discuss the value of left ventriclar ejection force (LVF) and corrected Q-V peak interval (QVc) by Doppler method,and that of the left ventricular systolic function (LVSF) by Doppler index. Methods: LVF and QVc were measured in 78 cases of coronary artery disease (CAD) and 50 cases of normal subjects(NS),and the results were compared with those of LVEF evaluated by two-dimensional echocardiography (2DE). Results: Between NS and CAD groups, the values of LVF and QVc were significantly different (p<0.05).There was a good corretation of LVF to LVEF, and of QVc to LVEF in CAD group, as well as in NS group. Conclusion: LVF and QVc are useful parameters for the assessment of LVSF.
