Key result
Three methods (cross-correlation, nonlinear association, and corrected cross-conditional entropy) were presented to assess changes in atrial signal dynamics induced by isoproterenol infusion.

Does isoproterenol infusion alter the determinism and dynamics of atrial signals during sinus rhythm and atrial fibrillation in patients?
This study presents linear and nonlinear signal processing methods to evaluate the effects of adrenergic stimulation on atrial conduction dynamics during sinus rhythm and atrial fibrillation.
Mainardi et al. (2006) conducted an observational in Sinus rhythm and atrial fibrillation. Isoproterenol infusion vs. Baseline (without isoproterenol) was evaluated on Changes in determinism and dynamics of atrial signals assessed via linear and nonlinear coupling parameters. Three methods (cross-correlation, nonlinear association, and corrected cross-conditional entropy) were presented to assess changes in atrial signal dynamics induced by isoproterenol infusion.
