Unipolar electrogram asymmetry correlates >0.99 with the equivalent dipole angle sine in computational atrial models.
Investigates the impact of epicardial-endocardial activation delays on electrogram morphology in remodeled atrial tissue.
Requires prospective validation before clinical use; extends computational models of electrogram morphology in remodeled atria.
Experimental evidences suggest the occurrence of epicardial-endocardial activation delays in structurally remodeled atrial tissue. Our aim was to investigate the consequences of this delay on electrogram morphology.

Irakoze et al. (2017) studied Electrogram morphology in atrial tissue. Computational monodomain model of atrial tissue was evaluated on Correlation between electrogram asymmetry and sine of the angle of the equivalent dipole. In a computational model of atrial tissue, unipolar electrogram asymmetry was strongly correlated with the sine of the angle of the equivalent dipole (correlation >0.999).
