Effect of α-Allocryptopine on Delayed Afterdepolarizations and Triggered Activities in Mice Cardiomyocytes Treated with Isoproterenol

Figure 4

Effect of ALL on in mouse ventricular myocytes. (a) The left inset shows current traces obtained by applying train pulses from −100 mV to +30 mV for 2 s after conditioned stimulus ranging from −80 to +50 mV at intervals of 150 ms. (b) The larger current densities induced by ISO were significantly reduced with 10 μM ALL treatment. (c) Current-voltage relationship showed that densities of inward ranging from −80 mV to 0 mV were decreased by treatment with ALL with the largest reduction of peak current at −60 mV. , versus control myocytes; , versus myocytes with ISO treatment.
