KCNH2, also known as the human ether-a-go-go related gene or hERG, encodes the Kv11. 1 channel proteins that conduct the rapidly activating delayed rectifier K+ current (IKr) in the heart. IKr plays a primary role in ventricular repolarization, and a decrease or loss in IKr is associated with an increased risk for the deadly cardiac arrhythmias (Sanguinetti et al., 1995). A major goal in cardiac safety assessment is to identify mechanisms that modify IKr, ventricular repolarization, and arrhythmogenic risk. To understand how IKr can be modified, one can think of IKr as being equal to the number of Kv11. 1 channels in the membrane (M), the open probability of the Kv11. 1 channels (Po), and the amplitude of the single Kv11. 1 channel current (i)(Hille, 2001).
