Action potential phenotypes in iPSC-CMs. (A) In a total of 22 cells, 2 different types of action potentials were recorded: atrial-like (left; mean of two cells) and ventricular-like (right; mean of 20 cells). Action potentials were elicited with 3-ms suprathreshold stimuli at 0.2 Hz. (B) Distribution of CMs according to their action potential phenotype: out of 22 cells, 2 cells were atrial-like and 20 cells were ventricular-like.
