Determination of instaneous cardiac rhythm parameters in multifractal dynamics model by regularized Newton’s method. (Russian. English summary) Zbl 1413.92004

A system of nonlinear equations of a multi-fractal dynamical model describing instantaneous cardiac rhythm in a regular domain and in the domain of step functions is found. The system of equations is solved numerically using a regularized scheme of Newton’s method. Numerical values of the multi-fractal model parameters with use results of the Holter monitoring are found for the patient of the Tver (a small town near Moscow) cardiac hospital.
