摘　　要：目的　寻找准确、形象、直观的无创性评价心脏功能的的方法 ,并探讨其临床应用的可行性。方法　鉴于多普勒超声心动图二尖瓣返流 (MR)频谱可代替左室压力曲线 ,对 30例心脏病伴 MR患者于超声心动图检查中采用声学定量 (AQ)技术记录其左室容积曲线 ;将两个图谱经扫描形成位图文件后输入自行编辑的心脏彩色压力容积环计算机软件系统中 ,经位图编辑和曲线处理自动生成左室压力容积环 (L VP- VL)。结果　所生成的L VP- VL形态稳定 ,定位准确 ,清晰度高 ,测值精确 ,重复性好 ,与以往心导管和心脏造影所描记的 L VP- VL环形及环体一致 ,各测值间无显著差异 (P>0 .0 5 )。结论　 MR频谱和 AQ无创技术描记的 L VP-Objective To explore a new non-invasive method of describing automaticly left ventricular(LV) pressure-volume loop(LVP-VL) for evaluating the cardial function.Methods The spectrum of mitral regurgitation(MR) in the stead of LV pressure curve and the volume curve obtained by acoustic quantification(AQ) technique in 30 patients combined a variety of heart diseases with MR were applied to form a picture file and entered the software system of cardiac colour pressure-volume loop(CCP-VL),and the system would describe automaticly LVP-VL.Results The LVP-VL described by above technique was stable in type,accurate in measurement,reliable in position and same with the LVP-VL described by catheterization.Conclusion The LVP-VL described by spectrum of MR and non-invasive technique is an effective method for evaluating the cardiac function.
