Background:

Cardiac electrophysiology simulations are crucial for understanding heart function.
Current Finite Element Method (FEM) solvers require high-quality meshes, which are time-consuming to generate for complex, patient-specific geometries.
This mesh generation bottleneck hinders clinical translation of in silico models.

Purpose of the Study:

To introduce an image-based, meshfree modeling approach for cardiac electrophysiology.
To automate model generation directly from imaging data.
To overcome the limitations of mesh generation in current simulation techniques.

Main Methods:

Developed an image-based model generation approach using the meshfree Mixed Collocation Method.
Built meshfree models directly from image data through an automated procedure.
Simulated electrical propagation in a porcine biventricular model.

Main Results:

The proposed meshfree method successfully simulated electrical propagation.
Results showed good agreement with solutions obtained using the Finite Element Method.
The method alleviated the need for mesh generation and reduced user input during modeling.

Conclusions:

The meshfree Mixed Collocation Method offers a viable alternative to FEM for cardiac electrophysiology.
This approach streamlines the generation of in silico models from medical images.
It has the potential to accelerate the clinical application of patient-specific cardiac simulations.
