Abstract
Using a recently formulated technique for in vivo cardiac transmembran e current estimation, we examined ventricular fibrillation for evidenc e of deterministic linear and nonlinear structure. Both unstable fixed point analysis and a newly formulated measure of nonlinear determinis m indicated that ventricular fibrillation in vivo exhibits determinist ic dynamics similar to those previously used in chaos control.
