Abstract
Using a recently formulated technique for in vivo cardiac transmembrane current estimation, we examined ventricular fibrillation for evidence of deterministic linear and nonlinear structure. Both unstable fixed point analysis and a newly formulated measure of nonlinear determinism indicated that ventricular fibrillation in vivo exhibits deterministic dynamics similar to those previously used in chaos control.Keywords
