Abstract
Based on surrogate data hypothesis testing method, this paper presents an improved nonlinear algorithm for analyzing deterministic chaotic signals, which can be applied to the analysis of abnormal rhythm electrocardiosignals. Ventricular tachycardia (VT) and ventricular fibrillation (VF) can be treated as nonlinear chaotic signals that are different from stochastic signals. On the basis of qualitative analysis theory in nonlinear dynamics, the authors forwarded a new definition of complexity rate and developed several relative detection methods for quantitative analysis of VT and VF. The results indicated that these qualitative analysis and quantitative analysis of VT and VF are objective and credible.
