"WebNonlinear methods (fractal analysis) of HRV measurement. Nonlinear methods are based on the chaos theory and fractal geometry. Chaos has been defined as the study of multivariable, nonlinear and nonperiodic systems. Chaos describes natural systems in a different way because it can account for nature's randomness and nonperiodicity. " - Hrv nonlinear
