The cardiac electrical activity can be described through a semilinear parabolic equation coupled with nonlinear ODE, together with a passive conductor model of the torso. We aim at indentifying ischemias, i.e. regions where the coefficients of the equations describing the cardiac electrical activity are altered, taking advantage of data acquired on the boundary of the torso. For this purpose, we formulate a constraint optimization problem with Total-Variation regularization and adopt a phase-field approach.
