A Corrigendum on
Real-Time Rotational Activity Detection in Atrial Fibrillation
by Ríos-Muñoz, G. R., Arenal, Á., and Artés-Rodríguez, A. (2018) Front. Physiol. 9:208. doi: 10.3389/fphys.2018.00208
In the original article, we neglected to include the funder Beca de la Sección de Electrofisiología y Arritmias de la SEC. Therefore, the Funding section was updated:
This work has been partly supported by MINECO/FEDER (ADVENTURE, id. TEC2015-69868-C2-1-R), Comunidad de Madrid (project CASI-CAM-CM, id. S2013/ICE-2845), and the grant Beca de la Sección de Electrofisiología y Arritmias de la SEC.
We found a caption error in Figure 8, where labels A–C should be reordered to (A) Sinus Rhythm. (B) Rotor. (C) Chaotic wavefront collision, and the sign of the second reference to +Γth should be changed to −Γth. The caption was updated to reflect this change:
Figure 8. Rotational activity detector in in silico signals. Detection performed on the three simulation scenarios. The method detects rotational activation if the value of Γ[n] exceeds the upper threshold +Γth or falls below the lower threshold −Γth. The sign of Γ[n] reflects the rotational gyre direction, being positive if the gyre matches the rotation mask spin (clockwise/counterclockwise depending on the chosen pattern), or negative if the propagation rotates in the opposite mask direction. For the simulation cases we applied the detection on the full Γ[n] and the interpolated grids to compare both outcomes. Signals from top to bottom: (A) Sinus rhythm. (B) Rotor. (C) Chaotic wavefront collision. Parameters were γ = 150 samples and Γth = γ/7.
Additionally, the caption in the Figure 12 should reference the Figure 7D, and not Figure 3C.
The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way.
The original article has been updated.
