Decoupled the multicellular tissue model into single cell (ODE) and diffusion (PDE) components for GPU parallelization.
Implemented optimization strategies tailored to virtual heart model features.

Main Results:

Successfully simulated electrical excitation wave conduction in a 3D sheep atrial model using the GPU algorithm.
Achieved a 200-fold speedup compared to traditional CPU implementations.
Demonstrated the feasibility of GPU parallelization through model component decoupling.

Conclusions:

An optimized GPU algorithm provides an efficient and cost-effective platform for 3D whole heart simulations.
GPU computing is a viable alternative for addressing the computational demands of large-scale cardiac modeling.
