Many cardiac drugs fail because they exhibit reverse rate dependence, prolonging ventricular action potentials at slow heart rates, where this is pro-arrhythmic, while failing to prolong action potentials at fast heart rates. The colored squares in the image show predictions that were obtained by testing the effects of multiple ion channel perturbations in multiple mathematical models. Through this analysis we identified perturbations that act with forward rate dependence, prolonging the cardiac action potential at fast heart rates (top traces) but not at slow rates (bottom traces). See Cummins et al.
