ECG成像（ECGI）是一种非侵入性的工具，用于从体表电位估计心脏电活动。最近，有显着的方法学改进，以及ECGI的验证反映了越来越多的已发表的研究的巨大进展。尽管取得了这一进展，ECGI既没有被整合到临床工作流程概念中，也没有就其实际好处（包括减少成本和手术时间）实现明确定位。主要障碍之一在于缺乏高质量的验证数据。在这方面，本研究的目标是评估三个完善的逆方法的性能为10个心脏起搏治疗（CRT）患者：基于模型的最快路线算法（FRA），数据驱动的Tikhonov正则化，和基于FRA的最大后验方法进行了分析。植入的起搏电极导线的位置可以从CT图像中准确获知，使其非常适合局灶性激动序列的ECGI准确性评估。
ECG imaging (ECGI) is a noninvasive tool for estimating cardiac electrical activity from body surface potentials. Recently, there have been significant methodological improvements as well as a tremendous progress in the validation of ECGI reflected by an increasing number of published studies. Notwithstanding this progress, ECGI has neither been integrated into the clinical workflow concept nor achieved a clear positioning regarding its practical benefits involving cost and procedural time reduction. One of the main hurdles lies in the scarcity of high quality validation data. With this respect, the goal of the present study is to evaluate performance of three well-established inverse methods for ten cardiac resynchronization therapy (CRT) patients: the model-based fastest route algorithm (FRA), data-driven Tikhonov regularization, and a FRA-based maximum a posteriori methods were analyzed. Locations of the implanted pacing leads were exactly known from CT images, making them perfectly suited for ECGI accuracy assessment of focal activation sequences.
