This paper demonstrates the usefulness of the index named the effective bandwidth for evaluating the estimation accuracy of HRV power spectrum. Computer simulation revealed that a combined method of the derivative of cubic spline interpolation (DCSI) method and the spline interpolated instantaneous heart rate series (SIHR) showed the best performance. The index will be effectively utilized for the objective evaluation of the HRV spectral estimation methods.
