Tissue Doppler imaging (TDI), is a new imaging tool that allows measurement of dyssynchrony. In several small studies, TDI predicted clinical response and reverse remodeling after cardiac resynchronization therapy (CRT). Moreover, it allowed detection of mechanical dyssynchrony in heart failure patients with narrow QRS. Using TDI, the selection criteria for CRT might be changed to include heart failure patients with narrow QRS. Furthermore, it will help predict responders to this therapy, hence decreasing the percentage of nonresponders and allowing a more cost-effective use of this new technology.
组织多普勒成像（TDI）是一种可用于测量不同步性的新型成像工具。在多项小型研究中，TDI可预测心脏再同步治疗（CRT）后的临床反应和逆向重构。此外，它还能检测QRS波狭窄的心力衰竭患者的机械不同步性。使用TDI，CRT的选择标准可能会改变，将QRS波狭窄的心力衰竭患者纳入其中。此外，它将有助于预测该治疗的反应者，从而减少无反应者的比例，并更经济高效地使用这项新技术。
