Abstract

We extended our application for the assessment of moving equivalent dipoles (ED) from the surface ECG by incorporating a BEM method to calculate potentials on the surface of a tailored human torso model and explored whether it could provide reliable ED trajectories from the 12-lead ECGs compared to those from the body surface potential map (BSPM) data. We used 17 recordings of the Dalhousie BSPM data (EDGAR) with ECG signals arising from different pacing sites in the same patient and tested for the congruency of the derived ED trajectory patterns of the 12-lead and BSPM data sets. We found that the ED trajectories from these two sets are mutually shifted or rotated by less than the median offset of 1.5 cm and deviation angle of 15°. We believe that assessing the ED trajectory with this accuracy may help improve the detection of depolarization abnormalities in the clinical setting.
使用量身定制的人体躯干模型评估12导联心电图的等效偶极子轨迹
我们扩展了我们的应用程序,通过结合BEM方法来计算定制人体躯干模型表面的电位,从而评估体表心电图的移动等效偶极子(ED),并探索与体表电位图(BSPM)数据相比,它是否可以从12导联心电图中提供可靠的ED轨迹。我们使用了17个Dalhousie BSPM数据(EDGAR)记录,这些记录来自同一患者不同起搏部位的ECG信号,并测试了12导联和BSPM数据集导出的ED轨迹模式的一致性。我们发现,这两组ED轨迹相互移动或旋转的中位偏移量小于1.5 cm,偏离角小于15°。我们相信,以这种准确性评估ED轨迹可能有助于提高临床环境中去极化异常的检测。
