在38例心脏病患者中进行了超声心动图和心导管的同步检查,应用新型的声学定量技术和自制的压力-容量环(P-VL)软件程序同步输入左室容量和压力曲线并自动描绘左室P-VL.结果表明,P-VL可直观地显示不同类型心脏病患者的左室功能状态,所得定量数据可全面反映左室的收缩和舒张功能,这一方法简便准确、重复性好,明显优于以往的手工描绘,为临床应用P-VL研究左室功能开辟了新的途径.

To develop a new method for automatically tracing left-ventricular pressure-volume loops(P-VLs),echocardiography and left heart catheterization were performed simultaneously in 38 cases with heart diseases.The left ventricular volume curves displayed by acoustic quantification technique and the left ventricular pressure curves recorded by calheterization were inputted into a computer system and P-VLs were automatically traced by a self-made software program.The result showed that P-VLs depict specific left ventricular functional patterns in different heart diseases and offer comprehensire and accurate quantification of the left ventrieular systolic and diastolic function.It is concluded that our method provides a simple,reproducible and reliable technique for automatically tracing P-VLs and hence should faciliate further investigation of the left ventricular function in clinical practice.
