心力衰竭患者普遍存在不同程度的心室内或心室间的不同步运动,现代影像学尤其是超声心动图新技术在评估心脏机械不同步运动的部位、范围及程度等方面日益发挥着重要作用。本文着重介绍了超声心动图新技术包括组织多普勒、斑点追踪、速度向量成像和实时三维超声在评价心肌运动的同步性方面的研究和应用进展。 Heart failure patients generally have different degrees of ventricular or ventricular asynchronous exercise, modern imaging, especially echocardiography new technology in assessing the location of the heart mechanical asynchronous movement, the extent and extent of play an increasingly important role. This paper focuses on the research and application progress of new echocardiography techniques, including tissue Doppler, speckle tracking, velocity vector imaging and real-time three-dimensional echocardiography in assessing the synchrony of myocardial motion.
