New Paper Introduces the Newest Version of DREAM for Cardiac Electrophysiology

We are pleased to announce the publication of a new paper, "A Cyclical Fast Iterative Method for Simulating Reentries in Cardiac Electrophysiology Using an Eikonal-Based Model", in the journal Engineering with Computers.

In this work, we present the latest version of the Diffusion Reaction Eikonal Alternant Model (DREAM), a computational model designed to simulate cardiac arrhythmias. This model integrates the eikonal model with conduction velocity restitution and alternates with an approximated reaction–diffusion model, offering a more efficient approach to studying complex cardiac electrophysiology. The key contributions of this paper include:

• Enhanced Computational Efficiency: DREAM enables reentry simulations at coarse resolutions, significantly improving computational speed compared to traditional reaction–diffusion models.
• Cyclical Fast Iterative Method: We introduce a novel cyclical fast iterative method to solve the eikonal equation, modeling reactivations and reentries in anisotropic media.
• Public Availability: The DREAM model is now implemented in the openCARP simulator, providing broader accessibility to the research community.

This achievement would not have been possible without the invaluable contributions of the authors: Cristian Barrios Espinosa, Jorge Sánchez Arciniegas, Stephanie Appel, Silvia Becker, Jonathan Krauß, Patricia Martínez, Laura Anna Unger, Marie Houillon, and Axel Loewe.

We also extend our gratitude to all members of the CaMo KIT for their support and contributions.
