Figure 7 Mathematical Modeling
(Left) (A) Electrograms from normal tissue; (B) fibrotic tissue showing low-amplitude fractionation; (C) tissue exposed to acetylcholine, showing high-amplitude fractionation. (Right) Tissue pattern followed by snapshots of the advancing wavefront. In normal tissue (A), the pattern is homogeneous. In fibrosis (B), gray areas represent inexcitable scar tissue. In tissue exposed to acetylcholine (C), darker shaded areas indicate patches of IKACh and lowered diffusion.
