【摘要】 心脏再同步化治疗已成为慢性心力衰竭患者非药物治疗的首选方式。传统上将QRS波群宽度作为心脏再同步化手术评估指标存在一定局限性,导致心脏再同步化术后无反应。术前评估心肌的机械运动不同步尤为重要,利用超声、MRI和CT等多种影像学检查检测心肌应变参数绘制牛眼图,可准确挑选合适患者,判断术中电极植入位置,预测心脏再同步化术后反应性。现将针对不同检查的应用及各自特点做一综述。更多还原

【Abstract】 Cardiac resynchronization therapy has become the preferred non-drug treatment for patients with chronic heart failure.Traditionally,QRS wave group width has limitation as an evaluation index of cardiac resynchronization therapy,which leads to no response after cardiac resynchronization therapy. Therefore,preoperative assessment of mechanical un-synchronization of myocardium is particularly important. Using ultrasound,MRI,CT and other imaging examinations to detect myocardial strain parameters to draw bull’s eye plot can accurately select suitable patients,determine the location of intraoperative electrode implantation,and predict the post-cardiac resynchronization therapy reactivity.This article will review the application and characteristics of different examinations.更多还原
