Summary of variabilities in hiPSC-CMs. Summary of variabilities in hiPSC-CMs. (A-F) Comparison of SD1, SD2, SDRR, SDSD, STV-APD50 and STV-APD90 in WT-CMs (n=63), HCMT-CMs (n=154) and HCMM-CMs (n=79). Data are mean±s.e.m. *P<0.05, **P<0.005 and ***P<0.0001; one-way ANOVA, post hoc Tukey test). (G-L) Representative AP traces (G,J), with superimposed 30 APs (H,K) and Poincaré plots of these APs from hiPSCs exhibiting low (black circles) and high (maroon circles) variabilities (I,L). Dashed line represents 0 mV. (For more detail, see Figs S6-S9.) Chandra Prajapati et al. Dis. Model. Mech. 2018;11:dmm032896 © 2018. Published by The Company of Biologists Ltd
