摘要

目的：应用实时三维超声心动图（RT-3DE）与组织速度成像（TVI）评价正常人左室心肌收缩同步性。方法：选择27例正常人，分别测量其左室心肌各节段组织速度收缩达峰时间（Tv）、最小容积达峰时间（Tmv）和心动周期，并计算其收缩达峰时间比值（Rst）。结果：应用RT-3DE和TVI均检测出正常人左室心肌12个节段之间的Rst无显著性差异（P>0.05）。应用RT-3DE和TVI技术所测的正常人左室心肌12个节段之间的Rst具有良好的相关性（r=0.814）。结论：RT-3DE及TVI均可无创、定量评价正常人左室心肌收缩同步性，但RT-3DE提供了一种更加快速、简便、准确的检测方法。

Abstract

Objective: To evaluate left ventricular myocardial systolic synchrony in normal subjects by real-time three-dimensional echocardiography(RT-3DE) and tissue velocity imaging(TVI). Methods: Twenty-seven normal subjects were selected randomly. The time to the point of peak velocity(Tv) during systolic phase, to the point of minimal volume(Tmv) and cardiac cycle were obtained by the on-line Qlab soft ware. Then the Rst was calculated. Results: There was no significant difference in Rst among the 12 segments of left ventricle in normal subjects by RT-3DE and TVI(P>0.05). Significant correlation existed between the Rst obtained by RT-3DE and the one calculated by TVI in normal subjects(r=0.814). Conclusion: Both RT-3DE and TVI can evaluate left ventricular myocardial systolic synchrony in normal subjects noninvasively and quantitatively, but RT-3DE can provide a novel, quick and convenient technique.
