Key result
A novel technique for reconstructing 3D activation fronts from intramural recordings achieved an average root-mean-square error of 1.58 ms compared to simulated ground truth values.
Why the study?
Changes in conduction velocity indicate diverse cardiac abnormalities, but measuring conduction velocity remains challenging, particularly within the myocardial volume.
A novel technique accurately reconstructs 3D activation fronts and estimates conduction velocities from sparse intramural recordings, providing a validated tool for experimental electrophysiology.

Enables study of activation changes in experimental models; leaves open clinical translation of sparse intramural mapping.
Good et al. (2019) studied Cardiac arrhythmias. Intramural wavefront reconstruction and 3D conduction velocity estimation vs. Simulated ground truth was evaluated on Root-mean-square error (RMSE) of reconstructed activation times compared to simulated values. A novel technique for reconstructing 3D activation fronts from intramural recordings achieved an average root-mean-square error of 1.58 ms compared to simulated ground truth values.
