Hello,
I am using a monodomain model for cardiac electrophysiology simulation, and trying to recover ECG signals. However, I encountered some problem.
In the tutorial experiments 7, I noticed that the monodomain model can utilize the $\phi_{\rm e}$ recovery technique to obtain extracellular potentials. Does this mean that I only need to place the heart within a torso, adjust its position and angle, obtain the coordinates of the ECG electrode positions on the torso surface, and use this coordinates as parameters for '-phie_rec_ptf'? In other word, I need not to insert the heart model into the torso model and simulate them together?
If I need to insert the heart model with the torso model for simulation, how should I set the electrophysiological properties of the torso? My current understanding is to assign 'phys_region 'and 'gregion 'properties to both the torso and heart, and only assign 'imp_region 'property to the heart, treating the torso as a volume conductor. Also, setting the positions of the ECG electrode and using them as parameters for '-phie_rec_ptf'. After simulation, post-processing the data to generate the ECG. Is this approach correct?
Thank you!
