Thank you for all the kind responses. I also want to make a similar article, where I calculate an ECG for the simulation, and then make and explain the changes necessary to make the ECG look realistic. A main challenge will be that the depolarization has to happen very fast relative to the repolarization, which may be computationally difficult for a cell-based simulation.
Also cool would be the inverse. Going from ECG to plausible simulated RD dynamics.
Indeed, but that problem is just so much more complex.
