Figure 2.
Effect of βARS on whole-cell AP and CaT. Baseline shown in solid lines, maximal βARS in dashed lines. A. Steady-state AP at CL = 1000. B. Simulated calcium transient at CL = 1000 ms in the presence of βARS shows increased amplitude and rate of relaxation compared to baseline. C. Steady-state APD as a function of pacing CL. D. Steady-state CaT amplitude rate-dependence.
