Figure 5.

Effect of HSYA on contraction and field potential signals in hiPSC-CMs. The impedance and field potential signals of hiPSC-CMs were monitored in real time after treatment with HSYA (2.5, 5, and 10 μM). (a) Representative merged images of contraction and field potential signals for 5.4 s. (b) Quantification analysis of contraction amplitude, beat rate, rising time, falling time, FP amplitude, and FP duration. ^#P < 0.05 vs. control group (the color of # is the same as that of the curve).
