KCNQ1 and cardiac arrhythmia: In addition to simulating the effects of PUFA analogues on the ventricular action potential duration, we also simulated the ability of 7 μM DHA-glycine (the most selective Kv7.1/KCNE1 activator) to prevent arrhythmia by simulating early afterdepolarizations using 0.1 μM dofetilide.
