Effect of IKur loss-of-function mutations on APs of atrial- and ventricular-like hiPSC-CMs. (A) Superimposed APs of an atrial-like hiPSC-CM upon injection of 12.5–100% virtual IKur through dynamic clamp and associated injected current (bottom panel), consisting of IK1, 12.5–100% IKur, and a short stimulus current. (B) Superimposed APs (top panel) and associated injected current (bottom panel) of a ventricular-like hiPSC-CM. APs elicited at 1 Hz by a 3-ms stimulus of 100 pA. Note difference in time scale between panels (A,B).
