Figure 3.

Simulated time series of AP (Panels A–E) and [Ca2+]i transients (Panels F–J) in characteristic points of bifurcation diagrams for WT mouse ventricular myocytes in Fig. 2 during periodic stimulation: Tstim = 30 ms (Panels A,F); Tstim = 40 ms (Panels B,G); Tstim = 45 ms (Panels C,H); Tstim = 50 ms (Panels D,I); Tstim = 100 ms (Panels E,J). Bursting [Ca2+]i transients are observed at Tstim = 45 ms (Panel H). INa with slow inactivation.
