Vectorcardiographic QRS area is a promising tool for patient selection and implantation guidance in cardiac resynchronization therapy (CRT). Research has mainly focused on the role of QRS area in patient selection for CRT. Recently, QRS area has been proposed as a tool to guide left ventricular lead placement in CRT. Theoretically, vector-based electrical information of ventricular fusion pacing, calculated from the basic 12-lead ECG, can give real-time insight into the extent of resynchronization at any LV lead position, as well as any selected electrode on the LV lead. The objective of this review is to provide an overview of the background of vectorcardiographic QRS area and its potential in optimizing LV lead location in order to optimize the benefits of CRT.
向量心电图QRS面积是心脏再同步治疗（CRT）中用于患者选择和植入指导的一种很有前景的工具。研究主要集中在QRS面积在CRT患者选择中的作用。最近，QRS面积已被提议作为指导CRT中左心室导线放置的一种工具。从理论上讲，根据基本的12导联心电图计算得出的基于向量的心室融合起搏电信息，可以实时洞察左心室导线在任何位置以及左心室导线上任何选定电极处的再同步程度。这篇综述的目的是概述向量心电图QRS面积的背景及其在优化左心室导线位置以优化CRT益处方面的潜力。
