973	 Estimation of Heart Parameters Using Skin Potential Measurements	 A fundamental problem of vector cardiography is the estimation of the state of the heart on the basis of skin potential measurements. A mathematical model relating ventricular dipoles to surface potentials is sketched. Then it is shown that the inverse problem-that of determining electrical heart parameters on the basis of skin potential measurements-may be viewed as a nonlinear multipoint boundary value problem. A feasible solution employing quasilinearization and high-speed digital computers is given.
