Figure 5

A: Isochronal maps during ryanodine infusion of 3 µmol/L. (a) without isoproterenol (ISO). (b) ISO infusion. B: The changes of cycle length in SAN by the treatments of ISO (0.03 µmol/L), ryanodine (Ryd, 3 µmol/L), and ZD7288 (ZD, 3 µmol/L). *P<0.001 vs. baseline. †P<0.01 vs. ISO treatment.
