A biatrial digital twin integrating electrophysiology, mechanics and circulation: from physiology to atrial fibrillation

This dataset accompanies the manuscript “A biatrial digital twin integrating electrophysiology, mechanics and circulation: from physiology to atrial fibrillation.” It contains the fine electrophysiology and coarse mechanics meshes used in the coupled simulations, including regional labels and fibre directions; baseline and calibrated model parameters; and processed numerical data underlying the physiological calibration, regional-diffusion comparison, sensitivity analysis, and atrial-fibrillation results. The original clinical images and the Alya simulation software are not included.
