If current and typical action potential (AP) of four groups. a–d If Current was detected in four groups using the patch clamp technique (n = 28). e Current density–voltage relationships in four groups (n = 28). f AP was detected in four groups. g APA, MDP level, 0-phase depolarization rate (dV/dt) and APD of four groups.*p < 0.05 compared to CHIR = 0 groups. APA, action potential amplitude; action potential duration; MDP, maximum diastolic potential
