Why the study?
Does the inclusion of inhomogeneous electric properties in forward models improve the accuracy of simulated body surface potentials compared to homogeneous models in a porcine model?

Homogeneous volume conductor models introduce substantial spatial inaccuracies in predicting body surface potentials, which are only partially mitigated by inhomogeneous models, potentially affecting inverse reconstructions.
No takes yet. Share an insight, caveat, or question.
Homogeneous models overestimate extrema despite good correlation; leaves open whether inhomogeneous properties meaningfully advance inverse ECG accuracy in humans.
Bear et al. (2015) studied this question.
