Self-organization of conducting pathways explains electrical wave propagation in cardiac tissues with high fraction of non-conducting cells
Fig 1
Wave propagation in neonatal rat cardiac monolayers with a large portion of non-conducting cells.
(a) Activation map for a sample with 66% of non-conducting cells. Activation times are colour coded. Red lines show the regions where the wave was blocked. White and black arrows show the main propagation pathways. Yellow square pulse sign indicates the location of the stimulating electrode. Yellow dashed lines outline the areas of slow conduction. The original video (S1 Video) of the wave propagation is available at https://youtu.be/3aDmsT1pl3Y. (b) Velocity decay with the increase of the portion of non-conducting cells in samples. The percolation threshold is shown with the dashed line and was equal to 75 ± 2%.
