Particle-based cardiac rhythm simulation

The cardiac dynamics simulation possesses the important research significance and the strong application value in bionic human organs manufacturing field. In this paper, we propose a particle-based model based on SPH (Smoothed Particle Hydrodynamics) which applies to cardiac rhythm simulation by combining with biomechanics, elasticity mechanics and topological knowledge. This model constrains the neighborhood of particles to keep the cardiac topological structure features, and introduces cardiac viscoelastic property to make the model better accord with the cardiac dynamics characteristics. And ultimately, we exert the simplified cyclical pace-making forces on the particles of the particle-based heart model to make the movement of the heart in accordance with a certain rhythm, to verify our cardiac dynamics simulation model. Experimental results show that our cardiac dynamics simulation model possesses high fidelity and strong robustness in cardiac rhythm simulation.
