Why the study?
Electrocardiographic imaging allows estimating epicardial electrical activity, but the effect of the number and distribution of torso mesh nodes on its accuracy required evaluation.
For electrocardiographic imaging (ECGI) in atrial fibrillation, torso meshes should have at least 400 nodes with a homogeneous distribution and node distances under 4 cm to achieve reliable reconstructions.
Answers are grounded in this paper and cite their sources.
May warrant denser homogeneous torso meshes in ECGI research; leaves open clinical translation in human AF.
Imaging (ECGI) allows estimating the epicardial electrical activity using anatomical information and body surface electrograms. In this study, the effect of the number and distribution of nodes constituting torso meshes on the ECGI accuracy is analyzed using atrial fibrillation (AF) simulations.

Alabau et al. (2022) studied Atrial Fibrillation (n=10). Torso mesh density (100 to 2000 nodes) vs. 4000 nodes reference torso was evaluated on Pearson's correlation coefficient (CC) of electrograms.
