Abstract	After analysing ƒ(α), the multifractal singularity spectrum of the synchronous 12-lead ECG signals (MSSSE), the authors find that the Δα(the range of singularity strength α) of MSSSE is dispersed. In order to quantitatively analyze curves of multifractal spectrum derived from 12-lead ECG signals, we compute both the Δᾱ(the mean of Δαs for 12-lead ECG) and the dispersing degree δΔα(defined as standard deviation of Δαs for 12-lead ECG signals) as characteristic parameters. With comparison of these characteristic parameters between the people with good health and heart disease, we find that the Δᾱs are close to each other, but the δΔαs are different. We also compare these characteristic parameters between the people with good health and brain disease, and find a dissimilar result, i.e. the Δᾱs are different from each other while the δΔαs are close. It implies that the characteristic parameters of multifractal spectrum are controlled by both the body's neurosystem and self-syntonic property of cardiac structures. Furthermore, the Δᾱ is related with neuroautonomic control on the ECG, and the δΔα is related with the spatial anisotropic propagation of the ECG signal in the myocardium.
