Abstract
Application of techniques derived from the theory of nonlinear dynamical systems to calculate a fractal dimension which characterizes a signal and can be used to gauge to what extent the signal is due to noise or arises from a deterministic dynamical system is discussed. These techniques are applied to surface ECGs from ventricular fibrillation. The results suggest that fibrillation is not significantly different from spectrally colored random noise
