#EikonalModel

Our use case partner Axel Loewe has published "A cyclical fast iterative method for simulating reentries in cardiac electrophysiology using an eikonal-based model": The DREAM model, which incorporates conduction velocity restitution and an approximated reaction-diffusion component, significantly accelerates the simulation of complex cardiac arrhythmias compared to traditional models.

Fig. 9 Left atrium posterolateral view of transmembrane voltage
maps of induced reentries at different time points after S2,
stimulated at a point near the mitral valve. a Monodomain
model with 200 m average edge length, b DREAM with
1600 m average edge length. Figure 9 shows an example where the DREAM shows a figure-of-eight reentry while the mono-
domain model shows a spiral reentry. This difference arose
from the lack of source-sink mismatch representation in
the DREAM. In both cases, the reentries were sustained
for the full 1000 ms simulated.
