NS5806 Induces Electromechanically Discordant Alternans and Arrhythmogenic Voltage-Calcium Dynamics in the Isolated Intact Rabbit Heart

Background: NS5806 activates the transient outward potassium current I(to), and has been claimed to reproduce Brugada Syndrome (BrS) in ventricular wedge preparations. I(to) modulates excitation-contraction coupling, which is critical in alternans dynamics. We explored NS5806-arrhythmogenic effects...
