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.

Control of Human Atrial Fibrillation
TLDR
Results are presented on the application and evaluation of chaos control for slowing and regularizing local electrical activation of the right atrium of humans during induced atrial fibrillation. Expand
Quasiperiodicity and chaos in cardiac fibrillation.
TLDR
Evidence indicated that fibrillation arose through a quasiperiodic stage of period and amplitude modulation, thus exemplifying the "quasiperio-temporal chaos" first suggested by Ruelle and Takens. Expand
Measuring temporal complexity of ventricular fibrillation
Abstract Temporal complexity of early ventricular fibrillation (VF) is re-assessed through measuring the correlation dimension D 2 , entropy K 2 and high-dimensional component σ from… Expand
Spatiotemporal complexity of ventricular fibrillation revealed by tissue mass reduction in isolated swine right ventricle. Further evidence for the quasiperiodic route to chaos hypothesis.
TLDR
A decrease in the number of wave fronts in ventricular fibrillation by tissue mass reduction causes a transition from chaotic to periodic dynamics via the quasiperiodic route. Expand
Chaos and the transition to ventricular fibrillation: a new approach to antiarrhythmic drug evaluation.
TLDR
Evidence is summarized that the transition from tachycardia to fibrillation is a transition to spatiotemporal chaos, with similarities to the quasiperiodic transition to chaos seen in fluid turbulence, which will support a new paradigm for antiarrhythmic drug classification. Expand
Extraction of physiological and clinical information from intra-atrial electrograms during atrial fibrillation: review of methods.
This paper presents a review of the evolution of methods and algorithms for the analysis of intra-atrial recordings, with special emphasis to the extraction of physiological and clinical information… Expand
Ionic Channels and Fibrillation
TLDR
Understanding the mechanisms underlying fibrillation of the heart is very critical as it is the most important cause of stroke in industrialized society. Expand
Deterministic patterns and coupling of bipolar recordings from the right atrium.
TLDR
The detection of spatio-temporal recurrent patterns and of non linear coupling together with the surrogate data results indicate that during atrial fibrillation a certain degree of local organization exists, likely caused by deterministic mechanisms of activation. Expand
