FPD and APD prolongation in hERG-deficient lines. a, b Signals of FPD recorded on days 30 and 60 by MEA in WT and KOs. c, d Quantification of FPD and FPDc. n = 3 independent experiments, unpaired t test. e, f Recording trace of APD on days 30 and 60 in WT and KOs. g Quantification of AP at APD50, APD70 and APD90. n = 3 independent experiments, unpaired t test. P < 0.05 was considered to be statistically significant (*P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001)
