     [摘要] 目的利用实时三维超声心动图评价冠心病的左室整体与局部运动及功能。方法用实时三维超声分别对正常组及冠心病组的整体左室收缩末容积、舒张末容积(ESV、EDV)及射血分数(EF)进行测量，并与二维超声心动图测值比较。用实时三维超声心动图对冠心病组的ESV、EDV和EF进行测量，并与正常组的测值进行比较。用实时三维超声心动图对冠心病组中心肌运动不良各节段的心室局部收缩末容积、局部舒张末容积(RESV、REDV)和局部射血分数(REF)进行测量，并与正常节段的测值进行比较。结果冠心病组实时三维超声测量的ESV、EDV及EF，与二维超声心动图测值间差异有显著性，与正常组测值间差异有显著性。正常组实时三维超声测量的ESV、EDV及EF，与二维超声心动图测值间差异无显著性。实时三维超声心动图测量冠心病组中心肌运动不良各节段的RESV、REDV和REF，与正常节段的测值间差异有显著性。结论实时三维超声心动图能全面显示冠心病患者整体和局部心室容积、室壁运动及功能动态变化情况，为冠心病的临床诊断与治疗提供更完整的定量信息。
